These were the first locks I learned how to pick. I wasn’t doing it to break in; I worked at a facility that had many offices and classrooms, and only janitors and senior administrators had master keys. Everyone else had keys that would only open specific types of doors ("O" for offices, "C" for classrooms, "S" for storage, etc.). I worked in the main office in a lowly clerical position and only had an "O" key. People would come to the main office if they had left their keys at home or didn’t have them for whatever reason, needing someone to unlock a door for them. Often there wasn’t anyone in the main office who had the appropriate key. After wasting far too much time tracking down an administrator or custodian, I decided to try my hand at lockpicking. Turned out I could open any door in the building with a bent paper clip.

At the last university where my dad worked, there was a key needed to access the elevator. The idea was that only faculty and staff could use it and the occasional student who needed special access. On the first day there, we were getting a tour from of my dad's new colleagues. He showed us the elevator and mentioned that you could use it without a key by pretending to use a key but just about anything would work. It turns out that you could use a penny to give a slight turn and call for the elevator. Years later, when I was a student there, that trick still worked. It allowed me to bypass the locked doors which kept you from getting off of the main floor and I could get to any floor. That also allowed me access to the sub-floor that had a tunnel to the building next door.
That makes sense though about why they wouldn’t bother changing it years later. If nobody but a handful of people know that you can open them without the key, no point in spending money to change the locks and get all new keys for faculty LOL
Just funny how much things like that are an illusion. And then they last for a very long time. It's not hard to keep people locked out of things because most are just not determined.

I love that I know this fact. That is a very intimidating LOOKING lock. A very impressive copout; if you want to trick people into thinking you are a less than reputable person.
Oh wow, that's worse than I was expecting. I was thinking that if you unlocked one cylinder, perhaps it allowed you to easily decode the other cylinder, essentially allowing anyone to make a master key.
You can still do this too. Once you have access to the back, you can pull the whole lock out and take it apart. Decoding it is then super easy with it out. Plop it back in once you have your key and boom. Worried about someone noticing the gaping hole? Replace it with an identical lock of any key. This will buy you either some time, or infinite time if they just replace it with a working one. They'll either notice the trickery, or most likely just throw away the evidence and replace it with a working one.
@@joblessalex Deviant Ollam talks about replacing the cylinder with one filled with mastering wafers (so literally any key would work, and no one would realize it since the key meant for the door still works). Decode the cylinder on your own time, then come back and swap the cylinders back. Boom, you have your master back, and you now have the key you need for other tasks (especially if it was part of a mastered set).
@@JaxMerrick yeppers! But really the question you need to ask is how often is this lock used? If it is a lot, will anyone have a repair man out in time? Will the repair man even check to see why it failed, or just throw it away and replace it? If he does check it, will he know you messed with it or just say "huh, that's weird"? High likelihood that it's overkill to master wafer it, but it is the safest way.
@@joblessalex Well, he's a pen-tester, so he usually looks for the least used, often unlocked cylinder (like a bathroom door). I don't know what your situation would be, but most people wouldn't even notice to call in a repair company.
Yeah. I was thinking that. Something tells me that similar mechanics were used by the Egyptians too. So a couple thousand years old design, not just one hundred as LPL said.
I mean, as far as only keeping our the honest people, this would do a great job. This warded lock weeds out keys that are both too high and too low, unlike regular warded locks which only restrict overheight keys.
Egregious is a most apt description. Looks like one could use a paperclip end hammered flat to open it. Coming soon. Lock sees LPLs covert companion, wets itself and just opens. Another top notch production of destruction! Greasing the doorknob would be more secure than that Yale core.
I was half expecting the wave rake to come out. Took me a moment to realize what the actual problem was, but as soon as you pointed out the caveat with the tailpiece, my brain immediately went to work trying to figure out how the hell the thing actuates. Did not take me long, and was pleased to find out I was right on the money! This really seems like one of those *really obvious things* that I'm almost impressed somehow got missed.
From watching this channel for a while now.... It would appear that those tend to go hand in hand more frequently than one would ever imagine. Sort of bizarre when you think about it. I wonder if lock companies get sued a lot?
This reminds me of a motel where I stayed in rural New Mexico. The clerk showed me the bungalow room and started off. I said, “wait, you forgot the key.” She said, “we usually don’t need keys here.” I said, “I would feel better with a key.” She told me to come along to the desk where she handed me a box with 16 or so keys in it. I took it back to the room and decided try a key, and the very first one worked. I thought, “the odds are at least 16:1.” I grabbed another different key and it worked. In fact all the keys in the box worked. Fortunately it was rural enough that the clerk was correct with her first statement! It is nice that places like that still exist in the US.
Watched this channel for so long, at first I was thinking "probably nothing shielding the mechanism, he will just reach behind the lock and rotate it opened", then you started picking the lock I was like "hmmmm, maybe no security pins?" then it was mentioned that core can be free rotated, I was like "hmm unsure where this is going" then you mentioned that the tip of the key is rotating the core, and then I knew, the problem is you can reach mechanism behind the lock and rotate it and open it"
I didn't get suspicious until I saw the brass gears at the top and bottom. Thought: Oh, Oh, freewheeling...and then he just shoved a glorified straightened bobby pin in, and, yup, opened. Did Master Lock steal all of Yale's failed 1920's designs?
This applies to 'nightlatch' cylinders only. Most Bicentric cylinders would be of the screw in mortise type. Mortise cylinders have a cam fastened to the end of the plug to drive the locking mechanism. A Bicentric mortise cylinder has two cams. One is fastened directly to the lower plug. The other slips over the lower plug and can move independently of the lower plug. It is driven via gears from the upper plug. With the mergers of lock companies (Yale is now part of ASSA-Abloy) Yale apparently ceased production of bicentric cylinders some years ago. This meant that institutions like MIT had to find an alternative cylinder to use. Possibly the advent of swipe card systems contributed to the demise of the bicentric cylinder. Interestingly an Australian company produces a cylinder (Galaxy) which could be regarded as a 'tricentric' cylinder. Although there is only one keyhole, there are three different key types where the bittings are completely independent of each other. As long as the correct key of one of the three types (which can be called 'grand master', 'sub master' and ordinary) is inserted, it will operate the lock. If the 'grand master' is lost, only that key needs to be changed, all the other existing keys do not need to be changed.
I guess this product was dropped because ASSA-Abloy already had other twin cylinder designs. At least in Finland (where Abloy is from) there are plenty of twin cylinder locks. Then again, modern Abloy locks are designed so that the key no longer operates the latch, it only engages the handle which then withdraws the latch and at the same time resets the cylinder. How I open my front door these days: take key out of pocket - insert key - turn key - turn key back - put key back in pocket - push handle down to open door. The thumb turn works the same way.
Tip of the key is probably the earliest and most used option for master key systems. It was and perhaps still is, the way that every "Master Lock" with symmetrical teeth on both sides is easily bypassed. All that's necessary is to grind away all of the teeth except the last ones at the tip. Where I used to work it was either a hammer and chisel or the universal key when I needed to get padlocks off of lockers that belonged to previous workers who left their locks behind.
This actually seems to be a brilliant way to deter most people trying to gain unauthorized entry because you're going to exhaust yourself with picking attempts and overthinking your failure that you won't just try to stick anything inside and turn it. Deterrence by misdirection and frustration
This flaw is also very common on cheaper euro cylinders with thumb turn. It can be fixed but it requires a more complex clutch mechanism especially when dealing with a thumb turn that isn't always at an exact position to the core like on a euro cylinder.
Y'know, I've picked a few locks and it's really not as easy as LPL makes it look. I'm convinced that his reputation is such that the lock community has his number, and they just pop open when they see him coming.
Your cliche is wrong. Honest people are not honest because of any lock. We are honest even where there are no locks. For example, we do not shoplift from any store, even where there is no security, or steal toys from neighbors' lawns, even where there is no doorbell camera. I suppose you were speaking only of yourself.
I thought lockpicking might be a nice hobby to try out, but just my luck, even only owning lockpicking tools seems to be illegal in Japan (where I live). *sigh* So I'll keep only watching I guess. Great video as always!
Having lockpicks on your person can be problematic in many places if you're under suspicion of a crime. For something you keep at home, it's not likely to get you in trouble, regardless of legality. This is an important aspect of law, there's the letter of the law, and there's how it is enforced in reality.
0:00 I do love it. When people show the KEYS (in detail) of a so-called high security lock. Hell - I don't need lockpicking skills, just a quick look at the key/s is/are sufficient for me to "cut-a-copy", along with making a blank with the grooves along it, from a piece of flat metal.
Hey there, LL. Another cool video, (big fan) but this one triggered a long lost memory: Back in the 80s I recall seeing dorm door locks with "I beam" or "H-section" siamesed keys, and parallel keyways, and I don't think I've seen the like before or since. Have you ever seen those and could you demonstrate one? Thanks. And keep up the awesome work.
Recently added one of these “new in box” to my collection, I noticed the same bypass being possible almost immediately. I still haven’t picked it open, but I do enjoy looking at it a lot.
@Starlight Cipher, what else would you expect to see advertised when the manufacturers/promoters of these products "....their pants" when they see how easily LPL defeats their "security locks".🤣
First locks I had to pick had a similar flaw; a bent paperclip could reach past the cylinder, rotate the lock (so it opened) but also then released the core to slide out the front! Got into the desks, but meant I also had to learn how to rebuild the lock to put it all back together again.
Even back in the 90s I only ever saw cylinder locks in student accommodation with a night latch mechanism on the other side, plus if labs/rooms did have stealable stuff they'd have an alarm.
Perhaps because most people breaking in to a room wouldn't even bother trying to pick the lock. A good run up and shoulder-ram and the frame will give way. The door is only as strong as the weakest point, and unless you've spent quite a lot of money on the frame and installation, that won't be the lock.
@@vylbird8014 while this may be true in many situations, I don’t think a security product should take a defeatist approach to design. If they do, they inevitably become the weakest link for scenarios where the rest of the setup is secure.
Or they model it after what's the intended use case. As an internal door lock and maybe only used to lock classrooms as to show you can't enter it seems fine. I worked at a school where we had a classroom with an emergency opening on the outside as it has the external emergency opening. Here everybody could then open it, but it was fine as it was just a way to tell students that the classroom was locked and they shouldn't enter. Not to keep out burglers and the like.
@@leonthebleh Got a nice contradiction at my school. The building was made for fire safety: The doors can't be locked from the inside, so a misbehaving student can't possibly lock themselves in. There are big class windows between classroom and corridor to permit a rapid sweep through the building searching all corners for anyone who hasn't evacuated. All of the security doors instantly unlock if the fire alarm goes off to permit rapid evacuation. All very well... until times shift, and suddenly people (ie, parents) are concerned about school shootings and demand that we put in place some sort of lockdown process. Which... we can't. There is no place to take shelter, because the building was designed without hidden corners where a trapped person might be missed. Teachers can't lock people out of the classroom, because the doors don't lock from within. And you can't prevent someone moving around the site, because all they need to do is press a fire alarm point. The latter two points couldn't be solved, but we did re-fit all the classroom locks so that they can be locked from within. And adjusted the PA system so we can put out different coded alerts: The regular fire alarm, the more worrying 'take shelter within the building' alarm, and the emergency 'run like fucking hell' alarm which is for use in the case of a gas leak or bomb threat.
@@leonthebleh if they advertise their usage and security assumptions it’s reasonable. The problem is they don’t and you can’t expect every customers to red team the lock for due diligence.
Looking through a few random videos, would it possibly be a situation that the vocal levels are automatically being normalised based on the loudest sound? As the loudest sound in this video at around 2.30 is a lock click that comes in at around -9db so everything else may be averaged lower based on that level. When you look at other videos, mostly it's the beginning intro words of 'this is the' which is the loudest speech, but always some sort of lock clicking is usually double the volume. I'm just thinking if that may be effecting the global voice volume :)
@@runed0s86 Unlikely, it only happens with LPL (and a small handful of other content creators), 99% of youtube videos are easily audible at my usual setting of 27, it's only the occasional person with quieter recordings (ie. LPL) which cause me to turn them up.
Reminds me of a door in a house I lived in... we didn't have a key to the lock - but you shoved any piece of sturdy material in there and turned and it'd open straight up. Choice of tool was the tip of a pair of scissors, may or may not have been stashed in a cabinet nearby for convenience Said door belonged to my bedroom at the time T-T;; nevermind that it was shared and all so there was possibility of being locked out
Well, now I know why the janitor at one university I was at carried what looked almost exactly like your bypass tool rather than a key. It's obviously less trouble with these locks.
@@penfold7800 It was similar to the light switch one (though that one was forked), but I saw him use it on doors on a many occasions. I had just assumed that was the "master key" or something. I suppose in a way it was :D
That's crazy... The idea is interesting but how did they miss something like that? Side note: Why is the volume so low on this channel now? There's a noticeable difference compared to videos a year ago.

Now that you have brought this up . . . [ Your Favorite Brand of Lock ] Kwikset SmartKey has a particular type or style of deadbolt lock that utilizes 2 separate cores for use in limited 2-level master-key systems such as those used in apartment buildings or apartment complexes that allow for managerial or supervisory access keys to be used with those particular locks due to the simple facts that Kwikset SmartKey technology does not allow for the techniques used in modern-day master-keying schemes (since Kwikset SmartKey does not use conventional pin-tumbler mechanisms .) What I like about the concept of bi-centric cylinders or cylinder housings is for the allowance of 2 separate and distinctively different keyway profile sections to be used in the same lock (one for the cylinder core that the individual change-key operates and a totally different or distinct one for the one that the master-key operates so as to prevent key interchange or an otherwise compromise in the master-key system, that is if a restricted keyway or profile section is used for the cylinder core that the master-key is to operate .) What I would want to see in such an arrangement is an SFIC (Small-Format-Interchangeable-Core) cylinder housing that accommodates two different SFIC cores for this exact purpose in the same cylinder housing that would allow for two independent key systems to operate the same locking hardware as found in a padlock or as that on a door or a series of doors as what would be found on an institutional campus of buildings, like that of what would be found on a military installation or a college campus or hospital/medical center campus . Maybe there could also be a cylinder housing configuration that would allow for situations or arrangements where "dual-custody" applications would be used such as that of where high-value inventories are stored or other storage scenarios where confidential or sensitive information is kept or stored, or proprietary research & development, and that or what could then be deployed with standardized door hardware, so as to change or restore the use of a single-keyed access application later or after a dual-custody arrangement is no longer needed, all without the further modification of the door or the lock that is used on that door . I think that you have featured a similar lock [padlock] used in Australia that uses two separate cores for very much the same purpose such as to allow two organizations with independent keying systems to operate a single padlock that would be utilized to secure a perimeter fence or gate that would be used to secure some form of infrastructure with out the need to link separate individually keyed padlocks together . I could very well see the use of a similar cylinder scheme used to this day for the purpose of particular situations where different group activities or departments within a large organization or institution, with their own distinct keys being used to operate a common set of doors or locks within a facility without the need to issue (or track) multiple keys or to modify cores or cylinders within those locks to accommodate distinctively different keying systems (that would also degrade security, since lock cores with multi-sectional keyway cylinders or maison-keyed cylinders that have a multitude of possible shearlines or entire pin-stacks removed altogether in order to facilitate the operation of multiple key bittings from multiple key systems .) Additionally, a bi-centric cylinder housing format that accepts 3rd-party manufactured cores or SFIC's would also allow for keys from different makes or manufactures to operate the same lock(s) within a facility or campus .
Although, unless you were told about this weakness or had an example of this lock to play around with, I can understand why it was considered pick-resistant: just picking a core doesn't get the tail-piece to turn and can't open the door, you must know that a tool can be inserted to bypass and turn a gear, which rotates the tail-piece itself.
I'm a fan, but live in Puerto Rico and shipping although provided the Government makes things harder for us, im visiting Iowa for a while and took the opportunity to finally buy a Sarter set with some waffle Gigglers, thank you for all your work is much appreciated.
Yale is part of Assa Abloy famous in Sweden for their very secure Assa 2000 home door lock that could be picked extremely easy as it turned out. They updated the lock a number of times sending new parts to existing customers until they gave up and said that it was good enough despite the lock still being way to easy to pick. Personally I have never bought an Assa lock since that time. Everyone makes mistakes but it is how you handle them that counts. Assa leaves the customer with the problem.
LPL I was waiting for you to disassemble the lock and show how it works, I know there are gears on the back and I know Yale made rim and mortise cylinders, They also made knob locks and pad locks with this system,
I just leave my doors unlocked after watching this channel. Like, F it. Just open my door, take whatever, just don't break my $100 lock that can be beat by an orange juice bottle.
Well that explains a lot... I picked up a tss euro thumbturn cylinder out of a junk box to play around with and found that just jamming a piece of old wiper blade to the back of the keyway and giving it a wiggle allowed me to turn the cylinder and move the action of the lock, presumably due to the same issue of not being directly linked. Slightly related note, I was actually thinking of switching an elderly relatives cylinders to thumb turns because they are struggling with keys due to dementia (remembering to lock their doors or taking the key out and forgetting where they put it after locking etc) so I might have to look into other options if this is s common design flaw. Having said that a lock which can be easily bypassed is probably better than them just not locking their doors or getting locked in. Having doors that automatically lock behind them and any kind of electronic mechanism would not be appropriate either because they wouldn't be able to learn this new method to unlock their door. Old age is just another one of life's cruelties I guess
The idea of decoupled actuator can also defeat some locks, whose security relies on the actuator being fixed when cylinder is locked. This can mean being able to push or work the bolt open with a knife, credit card or similiar.
Picking a lock by sticking a skinny screwdriver down the barrel and turning the mechanism at the back, completely bypassing the locking mechanism ... reminds me of a really cheap padlock I purchased in a $1 Store years ago. Expected a little better from a company Yale ...
I love the new thumbnail style!! You'd think it'd be such a small part of the content, but it's literally the first thing we see, and this one caught my eye right away! Fantastic work!
You should set up an obstacle course- a building or office with several types of doors and locks, one after another, and have a competition who can pick through the locks and doors fastest. The fact that the locks are installed or mounted to doors makes it harder. You can call it American Lockpicking Warrior. 😅
I get why they did it this way mechanically. A ratchet mechanism or something similar, that would allow the whole core to to turn and not just the tip, would have been a lot more complicated and expensive to make. But by doing it this way they completely undermined security.
Learned this rear level is a thing for cheap padlocks as an teen. You only need to move the level at the rear, for the padlocks it was not even an need to rotate. Now it this knowledge became viral on an University it would be bad :)

@@joblessalex Deviant Ollam talks about replacing the cylinder with one filled with mastering wafers (so literally any key would work, and no one would realize it since the key meant for the door still works). Decode the cylinder on your own time, then come back and swap the cylinders back. Boom, you have your master back, and you now have the key you need for other tasks (especially if it was part of a mastered set).
@@JaxMerrick yeppers! But really the question you need to ask is how often is this lock used? If it is a lot, will anyone have a repair man out in time? Will the repair man even check to see why it failed, or just throw it away and replace it? If he does check it, will he know you messed with it or just say "huh, that's weird"? High likelihood that it's overkill to master wafer it, but it is the safest way.
@@joblessalex Well, he's a pen-tester, so he usually looks for the least used, often unlocked cylinder (like a bathroom door). I don't know what your situation would be, but most people wouldn't even notice to call in a repair company.
So if I'm understanding this correctly, they effectively made a warded lock using pin tumbler only for the form factor
Yeah. I was thinking that. Something tells me that similar mechanics were used by the Egyptians too. So a couple thousand years old design, not just one hundred as LPL said.
I mean, as far as only keeping our the honest people, this would do a great job. This warded lock weeds out keys that are both too high and too low, unlike regular warded locks which only restrict overheight keys.
@@phillyphakename1255 Kind on neat, raking will also not work. All sorts of security ideas but protected only by obscurity while it lasts.
Don't discount the intimidation factor!
Egregious is a most apt description. Looks like one could use a paperclip end hammered flat to open it. Coming soon. Lock sees LPLs covert companion, wets itself and just opens. Another top notch production of destruction! Greasing the doorknob would be more secure than that Yale core.
" Lock sees LPLs covert companion, wets itself and just opens."
So, a standart MasterLock ?
The core seems fine, the problem is the atrocious design of the lock.
I mean that is pretty much what the bypass driver is xD
Greasy knobs are a pretty good deterrent
I was thinking flat head screwdriver myself.
I was half expecting the wave rake to come out. Took me a moment to realize what the actual problem was, but as soon as you pointed out the caveat with the tailpiece, my brain immediately went to work trying to figure out how the hell the thing actuates. Did not take me long, and was pleased to find out I was right on the money!
This really seems like one of those *really obvious things* that I'm almost impressed somehow got missed.
They really should have used a sidebar, or pin to lock the tail piece, but one that either key way could move to unlock it.
First I was thinking "wow this looks hard to pick"
I feel so silly now 🙃
He had me in the first half
It might be hard to pick per say but a 5yr old can bypass it
From watching this channel for a while now.... It would appear that those tend to go hand in hand more frequently than one would ever imagine. Sort of bizarre when you think about it. I wonder if lock companies get sued a lot?
This reminds me of a motel where I stayed in rural New Mexico. The clerk showed me the bungalow room and started off. I said, “wait, you forgot the key.” She said, “we usually don’t need keys here.” I said, “I would feel better with a key.” She told me to come along to the desk where she handed me a box with 16 or so keys in it. I took it back to the room and decided try a key, and the very first one worked. I thought, “the odds are at least 16:1.” I grabbed another different key and it worked. In fact all the keys in the box worked. Fortunately it was rural enough that the clerk was correct with her first statement! It is nice that places like that still exist in the US.
Was waiting for the other shoe to drop, and when it did it was not so much a shoe dropping as the contents of a boot shop!
Watched this channel for so long, at first I was thinking "probably nothing shielding the mechanism, he will just reach behind the lock and rotate it opened",
then you started picking the lock I was like "hmmmm, maybe no security pins?"
then it was mentioned that core can be free rotated, I was like "hmm unsure where this is going"
then you mentioned that the tip of the key is rotating the core, and then I knew, the problem is you can reach mechanism behind the lock and rotate it and open it"
I didn't get suspicious until I saw the brass gears at the top and bottom. Thought: Oh, Oh, freewheeling...and then he just shoved a glorified straightened bobby pin in, and, yup, opened.
Did Master Lock steal all of Yale's failed 1920's designs?
Double the lock, double the fun !

This applies to 'nightlatch' cylinders only. Most Bicentric cylinders would be of the screw in mortise type. Mortise cylinders have a cam fastened to the end of the plug to drive the locking mechanism. A Bicentric mortise cylinder has two cams. One is fastened directly to the lower plug. The other slips over the lower plug and can move independently of the lower plug. It is driven via gears from the upper plug.
With the mergers of lock companies (Yale is now part of ASSA-Abloy) Yale apparently ceased production of bicentric cylinders some years ago. This meant that institutions like MIT had to find an alternative cylinder to use. Possibly the advent of swipe card systems contributed to the demise of the bicentric cylinder.
Interestingly an Australian company produces a cylinder (Galaxy) which could be regarded as a 'tricentric' cylinder. Although there is only one keyhole, there are three different key types where the bittings are completely independent of each other. As long as the correct key of one of the three types (which can be called 'grand master', 'sub master' and ordinary) is inserted, it will operate the lock. If the 'grand master' is lost, only that key needs to be changed, all the other existing keys do not need to be changed.
I guess this product was dropped because ASSA-Abloy already had other twin cylinder designs. At least in Finland (where Abloy is from) there are plenty of twin cylinder locks.
Then again, modern Abloy locks are designed so that the key no longer operates the latch, it only engages the handle which then withdraws the latch and at the same time resets the cylinder. How I open my front door these days: take key out of pocket - insert key - turn key - turn key back - put key back in pocket - push handle down to open door. The thumb turn works the same way.
and the swipe cards are just as easy to bypass lol
Tip of the key is probably the earliest and most used option for master key systems.
It was and perhaps still is, the way that every "Master Lock" with symmetrical teeth on both sides is easily bypassed. All that's necessary is to grind away all of the teeth except the last ones at the tip.
Where I used to work it was either a hammer and chisel or the universal key when I needed to get padlocks off of lockers that belonged to previous workers who left their locks behind.
You can pick this lock without actually picking anything. That's incredible.
This actually seems to be a brilliant way to deter most people trying to gain unauthorized entry because you're going to exhaust yourself with picking attempts and overthinking your failure that you won't just try to stick anything inside and turn it.
Deterrence by misdirection and frustration
This flaw is also very common on cheaper euro cylinders with thumb turn. It can be fixed but it requires a more complex clutch mechanism especially when dealing with a thumb turn that isn't always at an exact position to the core like on a euro cylinder.
Y'know, I've picked a few locks and it's really not as easy as LPL makes it look. I'm convinced that his reputation is such that the lock community has his number, and they just pop open when they see him coming.
master key: "admin"
Locks only keep honest people out. Great videos as always
Yes that's true but you want to slow down the dishonest people ...if you can't make it this easy
A good lock only buys time. If they want it they will get it.
Not entirely true. They keep dumb people out too
@@shadowbanned3716 True dat.
Your cliche is wrong. Honest people are not honest because of any lock. We are honest even where there are no locks. For example, we do not shoplift from any store, even where there is no security, or steal toys from neighbors' lawns, even where there is no doorbell camera.
I suppose you were speaking only of yourself.
Masterlock: Write this down, write this down!
I thought lockpicking might be a nice hobby to try out, but just my luck, even only owning lockpicking tools seems to be illegal in Japan (where I live). *sigh* So I'll keep only watching I guess. Great video as always!
Come to America. You can buy most anything here lol
There are a few videos where LPL uses more common things.
In many coutries lockpicks are in the gray zone.
Burglary tools are illegal, but hobbyist toys are legal.
Just like a hammer or a crowbar.
Having lockpicks on your person can be problematic in many places if you're under suspicion of a crime. For something you keep at home, it's not likely to get you in trouble, regardless of legality.
This is an important aspect of law, there's the letter of the law, and there's how it is enforced in reality.
This can even go the other way, where you get punished that's technically not the law, deserved or not
It's a Yale lock. In the UK, we used to think of them as Americans think of Master locks...
Yeah, even though this one is discontinued, Yale seems to be the brand ASSA uses for dubious products.
0:00 I do love it.
When people show the KEYS (in detail) of a so-called high security lock.
Hell - I don't need lockpicking skills, just a quick look at the key/s is/are sufficient for me to "cut-a-copy", along with making a blank with the grooves along it, from a piece of flat metal.
Hey there, LL. Another cool video, (big fan) but this one triggered a long lost memory: Back in the 80s I recall seeing dorm door locks with "I beam" or "H-section" siamesed keys, and parallel keyways, and I don't think I've seen the like before or since. Have you ever seen those and could you demonstrate one? Thanks. And keep up the awesome work.
BRB, gonna go get me some free learning at Yale.
One thing I've learned watching this type of video is that security by obscurity is alive and well in the lock industry. :)
Recently added one of these “new in box” to my collection, I noticed the same bypass being possible almost immediately. I still haven’t picked it open, but I do enjoy looking at it a lot.
Long time watcher here, just so you know your channel is the only one I get ads for adult diapers on!!😂😂 Love your content.
More secure than a Master Lock.
you know they are based on your search history ?
@Starlight Cipher, what else would you expect to see advertised when the manufacturers/promoters of these products "....their pants" when they see how easily LPL defeats their "security locks".🤣
@@Hybris51129 But equally full of crap. =D
@@variouselite
Hopefully not on arrival...
First locks I had to pick had a similar flaw; a bent paperclip could reach past the cylinder, rotate the lock (so it opened) but also then released the core to slide out the front! Got into the desks, but meant I also had to learn how to rebuild the lock to put it all back together again.
Could you make a video on how you go about finding flaws in a lock? I think it would be pretty interesting to see the things you try.
I enjoyed this. I'd like to see more commercial brands.
Even back in the 90s I only ever saw cylinder locks in student accommodation with a night latch mechanism on the other side, plus if labs/rooms did have stealable stuff they'd have an alarm.

Great video thanks for sharing.
It seems LPL have upped his game with the thumbnail.
that's just... wow. Those locks TRULY had a grand master key, one key works on ANY of them, anywhere in the world!
It seems like most lock manufactures don’t threat model their products. Quite insane.
Perhaps because most people breaking in to a room wouldn't even bother trying to pick the lock. A good run up and shoulder-ram and the frame will give way. The door is only as strong as the weakest point, and unless you've spent quite a lot of money on the frame and installation, that won't be the lock.
@@vylbird8014 while this may be true in many situations, I don’t think a security product should take a defeatist approach to design. If they do, they inevitably become the weakest link for scenarios where the rest of the setup is secure.
Or they model it after what's the intended use case. As an internal door lock and maybe only used to lock classrooms as to show you can't enter it seems fine. I worked at a school where we had a classroom with an emergency opening on the outside as it has the external emergency opening. Here everybody could then open it, but it was fine as it was just a way to tell students that the classroom was locked and they shouldn't enter. Not to keep out burglers and the like.
@@leonthebleh Got a nice contradiction at my school. The building was made for fire safety: The doors can't be locked from the inside, so a misbehaving student can't possibly lock themselves in. There are big class windows between classroom and corridor to permit a rapid sweep through the building searching all corners for anyone who hasn't evacuated. All of the security doors instantly unlock if the fire alarm goes off to permit rapid evacuation. All very well... until times shift, and suddenly people (ie, parents) are concerned about school shootings and demand that we put in place some sort of lockdown process. Which... we can't. There is no place to take shelter, because the building was designed without hidden corners where a trapped person might be missed. Teachers can't lock people out of the classroom, because the doors don't lock from within. And you can't prevent someone moving around the site, because all they need to do is press a fire alarm point.
The latter two points couldn't be solved, but we did re-fit all the classroom locks so that they can be locked from within. And adjusted the PA system so we can put out different coded alerts: The regular fire alarm, the more worrying 'take shelter within the building' alarm, and the emergency 'run like fucking hell' alarm which is for use in the case of a gas leak or bomb threat.
@@leonthebleh if they advertise their usage and security assumptions it’s reasonable. The problem is they don’t and you can’t expect every customers to red team the lock for due diligence.
I spent 7 years with those locks and had no idea. I could have made so, so much mischief.
LPL, please set your audio to a higher volume. I always have to turn my speakers up to 100 to be able to hear your soothing voice!
I use a small Bluetooth speaker with my phone and the volume is pretty loud.
Sounds like you have some sort of speaker problem. I can hear him just fine at 30%
Looking through a few random videos, would it possibly be a situation that the vocal levels are automatically being normalised based on the loudest sound? As the loudest sound in this video at around 2.30 is a lock click that comes in at around -9db so everything else may be averaged lower based on that level. When you look at other videos, mostly it's the beginning intro words of 'this is the' which is the loudest speech, but always some sort of lock clicking is usually double the volume. I'm just thinking if that may be effecting the global voice volume :)
@@runed0s86 Unlikely, it only happens with LPL (and a small handful of other content creators), 99% of youtube videos are easily audible at my usual setting of 27, it's only the occasional person with quieter recordings (ie. LPL) which cause me to turn them up.
@@SuperNeilAdams sounds like a you problem
I was assured at first when there was no wave rake. But then that happened
you were technically correct, the best kind of correct
Got to love when a bot steals your early comment 😂
Masterlock: we didn't even THINK of that level of flaw.
“I am the Keymaster!”
“I am the Gatekeeper!”
“Hello, I am the Lock Picking Lawyer…”
Reminds me of a door in a house I lived in... we didn't have a key to the lock - but you shoved any piece of sturdy material in there and turned and it'd open straight up. Choice of tool was the tip of a pair of scissors, may or may not have been stashed in a cabinet nearby for convenience
Said door belonged to my bedroom at the time T-T;; nevermind that it was shared and all so there was possibility of being locked out
Those FOOLS!
The Auto Captions on RUclips can be so funny.. on this one.. at the start it says, "This is the walk begin lawyer". Great video.. as always.
Well, now I know why the janitor at one university I was at carried what looked almost exactly like your bypass tool rather than a key. It's obviously less trouble with these locks.
Or it was a tool to open toilet roll despensers, or turn on/off 'secure' light and heating switches.
@@penfold7800 It was similar to the light switch one (though that one was forked), but I saw him use it on doors on a many occasions. I had just assumed that was the "master key" or something.
I suppose in a way it was :D
My 1950s Courthouse uses those on the first 3 floors.
The custody areas use Folger Adams mogul cylinders.
That's crazy... The idea is interesting but how did they miss something like that?

Now that you have brought this up . . . [ Your Favorite Brand of Lock ] Kwikset SmartKey has a particular type or style of deadbolt lock that utilizes 2 separate cores for use in limited 2-level master-key systems such as those used in apartment buildings or apartment complexes that allow for managerial or supervisory access keys to be used with those particular locks due to the simple facts that Kwikset SmartKey technology does not allow for the techniques used in modern-day master-keying schemes (since Kwikset SmartKey does not use conventional pin-tumbler mechanisms .) What I like about the concept of bi-centric cylinders or cylinder housings is for the allowance of 2 separate and distinctively different keyway profile sections to be used in the same lock (one for the cylinder core that the individual change-key operates and a totally different or distinct one for the one that the master-key operates so as to prevent key interchange or an otherwise compromise in the master-key system, that is if a restricted keyway or profile section is used for the cylinder core that the master-key is to operate .) What I would want to see in such an arrangement is an SFIC (Small-Format-Interchangeable-Core) cylinder housing that accommodates two different SFIC cores for this exact purpose in the same cylinder housing that would allow for two independent key systems to operate the same locking hardware as found in a padlock or as that on a door or a series of doors as what would be found on an institutional campus of buildings, like that of what would be found on a military installation or a college campus or hospital/medical center campus .
Maybe there could also be a cylinder housing configuration that would allow for situations or arrangements where "dual-custody" applications would be used such as that of where high-value inventories are stored or other storage scenarios where confidential or sensitive information is kept or stored, or proprietary research & development, and that or what could then be deployed with standardized door hardware, so as to change or restore the use of a single-keyed access application later or after a dual-custody arrangement is no longer needed, all without the further modification of the door or the lock that is used on that door .
I think that you have featured a similar lock [padlock] used in Australia that uses two separate cores for very much the same purpose such as to allow two organizations with independent keying systems to operate a single padlock that would be utilized to secure a perimeter fence or gate that would be used to secure some form of infrastructure with out the need to link separate individually keyed padlocks together .
I could very well see the use of a similar cylinder scheme used to this day for the purpose of particular situations where different group activities or departments within a large organization or institution, with their own distinct keys being used to operate a common set of doors or locks within a facility without the need to issue (or track) multiple keys or to modify cores or cylinders within those locks to accommodate distinctively different keying systems (that would also degrade security, since lock cores with multi-sectional keyway cylinders or maison-keyed cylinders that have a multitude of possible shearlines or entire pin-stacks removed altogether in order to facilitate the operation of multiple key bittings from multiple key systems .)
Additionally, a bi-centric cylinder housing format that accepts 3rd-party manufactured cores or SFIC's would also allow for keys from different makes or manufactures to operate the same lock(s) within a facility or campus .
Although, unless you were told about this weakness or had an example of this lock to play around with, I can understand why it was considered pick-resistant: just picking a core doesn't get the tail-piece to turn and can't open the door, you must know that a tool can be inserted to bypass and turn a gear, which rotates the tail-piece itself.
Fascinating, I'm impressed 👍.
Seems like a precision flat-head screwdriver, something easily acquired in any hardware store, could also easily pick this open.
I'm a fan, but live in Puerto Rico and shipping although provided the Government makes things harder for us, im visiting Iowa for a while and took the opportunity to finally buy a Sarter set with some waffle Gigglers, thank you for all your work is much appreciated.
@lovemercy-qs1qg Thank you!
Yale is part of Assa Abloy famous in Sweden for their very secure Assa 2000 home door lock that could be picked extremely easy as it turned out. They updated the lock a number of times sending new parts to existing customers until they gave up and said that it was good enough despite the lock still being way to easy to pick. Personally I have never bought an Assa lock since that time. Everyone makes mistakes but it is how you handle them that counts. Assa leaves the customer with the problem.
Oh man it's been a while since I shouted "oh ffs!" at my phone so thank you LPL for reminding me🙂
LPL I was waiting for you to disassemble the lock and show how it works, I know there are gears on the back and I know Yale made rim and mortise cylinders, They also made knob locks and pad locks with this system,
I just leave my doors unlocked after watching this channel. Like, F it. Just open my door, take whatever, just don't break my $100 lock that can be beat by an orange juice bottle.
Well that explains a lot... I picked up a tss euro thumbturn cylinder out of a junk box to play around with and found that just jamming a piece of old wiper blade to the back of the keyway and giving it a wiggle allowed me to turn the cylinder and move the action of the lock, presumably due to the same issue of not being directly linked.
Slightly related note, I was actually thinking of switching an elderly relatives cylinders to thumb turns because they are struggling with keys due to dementia (remembering to lock their doors or taking the key out and forgetting where they put it after locking etc) so I might have to look into other options if this is s common design flaw. Having said that a lock which can be easily bypassed is probably better than them just not locking their doors or getting locked in. Having doors that automatically lock behind them and any kind of electronic mechanism would not be appropriate either because they wouldn't be able to learn this new method to unlock their door. Old age is just another one of life's cruelties I guess
The idea of decoupled actuator can also defeat some locks, whose security relies on the actuator being fixed when cylinder is locked. This can mean being able to push or work the bolt open with a knife, credit card or similiar.
As soon as I saw the decoupled tailpiece I knew where he was going with it.
I don't have other words for this other than "WHAT????" when he said that tip of the key moves it.
Kentucky ballistics had some safes on the other day and everyone thought of you. Was surprised how many shared viewers you guys have.
Brilliant idea, the pins were only there so that the key would turn, it was the tip of the key that unlocked the lock.
On the plus side, they can truthfully describe the lock as unpickable!
Picking a lock by sticking a skinny screwdriver down the barrel and turning the mechanism at the back, completely bypassing the locking mechanism ... reminds me of a really cheap padlock I purchased in a $1 Store years ago. Expected a little better from a company Yale ...
Great video and very informative.
This is like locking a door with a red button next to it.
Amazing innovative pick-proof design!

You got to love when the lock and key are just a decoration
You should set up an obstacle course- a building or office with several types of doors and locks, one after another, and have a competition who can pick through the locks and doors fastest. The fact that the locks are installed or mounted to doors makes it harder. You can call it American Lockpicking Warrior. 😅
Very interesting. Thank You. 🔓
Oh my gosh that’s crazy 😂thanks for sharing
I get why they did it this way mechanically. A ratchet mechanism or something similar, that would allow the whole core to to turn and not just the tip, would have been a lot more complicated and expensive to make.
But by doing it this way they completely undermined security.
Wow! This lock is unpickable! :)
Lpl just doesn’t realize that Yale designed the lock for the grandmaster key to BE the bypass driver.
I know a lock with the same coupling principle of the key tip that was made pick proof but still works the same way with some clever geometry
Learned this rear level is a thing for cheap padlocks as an teen. You only need to move the level at the rear, for the padlocks it was not even an need to rotate.
Now it this knowledge became viral on an University it would be bad :)
Have a nice day. It sure seems to me like these corporations should have liability for such defective products.
I sure hope yale have improved their security since - I've just recieved my Yale digital deadlatch upgrade. Love your videos LPL!
Man when you showed how easy to bypass I unreality LOL IRL. Haha Ty. 😊
And here I was thinking it was one of those "You need 2 people with 2 different keys" kind of locks.
Excellent video!
Oh god, I realised what was wrong with this about 5 seconds before you showed the flaw. Could not believe it 😂
I've learned so much from you. I'm into it Thx.
Good job showing how easy it was to pick 🔒.
