For the way you wanted to open it, I think the plastic was soft enough within just the first 30 seconds to rotate it, had you clamped it or used a welding glove to hold it properly so you could crank some leverage into it.
My experience with locks comes from 11 years as a Maintenance Chief for a State penitentiary. In that capacity, I employed hundreds of convicts over the years working under Employee supervisors as maintenance crew- I naturally, developed working relationships with a great many professional thieves, burglars and con men (not to mention several murderers). As to your question, 'Is your defeat method of this lock practical- Yes! Absolutely. Many of the professionals I knew would have probably gone through that lock with a cutting torch if they were going to bring fire to the task. But, they probably would not have been worried about the 4 minutes even with the little soldering torch. You and I would be worried about the time. But, most pros know they have plenty of time. I knew a convict who stole a rare motorcycle from a home in broad daylight from a well secured garage- he used a chain saw and simply cut the wooden garage door open making a whole new door, rolled the bike out and rode away on it, leaving the stolen chain saw behind in exchange. Neighbors did not even call the police. They thought he was a repair man. Who would steal like that? One thing convicts know well is people. They also know boldness very often pays big dividends. For any lock manufacturers out there, I would highly recommend you hire a few ex-cons as advisers. In fact, you should hire two teams- one to help design locks, the other to defeat them. I love watching your videos because your solutions are so unique. You very much think like an experienced convict- no offence intended.

I think if you need a plumbers torch it isn't an exploit any more than an angle grinder cutting it would be. Try it with a creme brule torch and see if that works.
@@JasperJanssen Angle Grinders can cut through anything. You can buy a bike lock made of 10 mm diamond rings and an angle grinder will probably cut through it with a bit of effort. . Fortify what you can, don't sweat what you can't. Put an alarm on, a gps device, or maybe a skunklock type of thingy could help.
Induction hears work only for steel and ferrous metals. Plastic is not affected, and heating the lock body red hot just for the tiny amount of heat going from the body to the plastic thing.. is quite inefficient.
Tiny amount of heat? Would you stick your dingus in a metal tube being heated red hot by an indution heater? I don't think so buddy. If you did you'd need a portable power supply each time you went to bed with a lady friend.
A common portable cutting torch needs no external power and would cut anything that size laughing all the way. I use a medical oxygen cylinder for light weight on my portable setup and use disposable propane cylinders with an adapter which is easy to assemble from standard fittings. It's easy to carry in the field (I'm a mechanic.) Torches aren't completely silent but a small tip isn't loud at all. Example quality kit: www.amazon.com/Harris-4403211-Acetylene-Cutting-Cylinders/dp/B01ES9CXVM You can find similar for less money. Harbor Freight kits work but are prone to mixer tube fires in the cutting torch head and their o-rings I've seen (where the cutting head joins the handle) tended to crumble. You could replace those with Viton rings from a non-shit manufacturer.
Armature comment. Open area bike lock, no. Garage, alley or construction site yes. A-1) Cut off the plastic with a carpet knife. 2) Using several eight by eight inch fiber glass mats over the lock for heat retention, pour diesel into shackle holes. Diesel is far more destructive when it burns. Might use "sugar rocket" paste as well to get it going. 3) While burning the inside, use a chain or tool to pull the lock body away from the shackle. B) Second approach, use a pipe and strap to hold a home made or Estes rocket motor over the key way and then insert a screwdriver. Again the fiberglass or even wet rags are put over the lock body to reduce noise, flames and people looking. Thank you LPL for helping us make "a more informed lock purchase"
The hottest part of the flame is towards the tip. If the core is of a material that can be melted, play the tip of the flame towards the back and top instead. That amount of plastic should have succumbed within 90-120 seconds. Think of it as a brazing job.
The plastic was supporting the metal locking parts. You melted the support. I think your screw driver had nothing to do with it opening. If you had mounted this in a big table vise you would have been able to pry the shackle open much easier. I think Fire Marshall Bill would recommend you wear welding gloves for this experiment.
If the thief "had" a hammer he could have tapped it out sooner. Also i think that the screwdriver would have worked better had he smashed it into the lock first with the hammer and then heated it. Now the whole lockbody just slipped away everytime he inserted the screwdriver.
who needs a hammer or vice when a simple pair of channellocks would have done the job? the shackle is already held in place by the disc brake, so all you have to do is pull on the body when heating. could've had it open in a minute or two.
*Him* :"I found an exploit that doesn't require any special tools" *Also him* : "all you need is a plumbers blowtorch *Me* : ah yes of course, the most common of all tools, blowtorches.
Well to be fair, a plumber's blowtorch is something you'll be able to buy in just about any decent hardware store. Specialised lock-picking tools, not so much. So in that sense, a blowtorch isn't 'special'.
I think you could of opened that faster than you did, i have a sneeking suspicion that you did not get enough leverage on the bottom of the lock fast enough you were using the screwdriver and tapping it rather than pulling with force, once you changed position and pushed with the torch it popped off easy, suggesting the plastic was well molten by then, im sure you would only need the plastic malleable to spin the lock ...
Unlikely to be exploited in the field, but easy enough for Kryptonite to engineer (cheaply) around in the same manner as the New York Lock. Makes you wonder why they did this. The answer I guess is they figure most people will never realise the weakness. Keep up the good work.
@@CptJistuce remember the scene in the first Jurassic park when they are excavating the fossilized dinosaur skeleton, well to help with the excavation they fire a large caliber round, most likely the 12g, into the ground to help loosen up the fossil of the dinosaur.
@@dereklyons6885 I do remember! (They were actually creating a shockwave that would travel through the rocks and reflect back, so that they could image the area using sonar. )
LOLDONGS I suspect they thought "No one is daft enough to lug a propane torch and set fire to it for 5 minutes as a real world attack when a disc cutter takes 20 seconds."
+Nigel Tolley Perhaps, but I'm sure I could do this is FAR less time knowing what I know now. As far as lugging tools around, thieves regularly carry tools far larger and heavier.
That's what I hate about plastic cores, the melting point of plastic, and it's just plain cheap, not durable. As far as this being practical, it would depend on the location and situation. The smells of burning plastic carry pretty far, and most people will look around to see what's burning. Also fire around a motorcycle could end up in one crispy critter. 😂 But obviously it works. Excellent video LPL.
A hydraulic bolt cutter is a silent beast. No sound, no wrestling with the chain to find a proper anchor for the bolt cutter, because the hydraulic one requires a lot lower force to operate and the force between jaws does not drop as soon as you let go, but maintains and only increases with each pump.. so it can swiftly cut anywhere, mid-air, without counter force. A separate low volume rotary pump is compact and the cutter head is quite small and easy to reach tight spaces. (also does not matter much where it bites.. you can chop the whole lock in two) And there are even hydraulic bolt cutter operated by electric drill. 2 seconds and 15mm shackle is toast. The best thing is that these kind of tools are very expensive and highly specialized and not common.. so at least that's going for us defending against thieves. But just as you do the overkill ramset gun tests, maybe you source such a hydraulic bolt cutter and do some videos with it. I've played with such a tool from a buddy who's into big construction sites where such cutters are used to cut thick rebar ends (30+mm), and cut a bunch of things to my amazement.
for safety, never apply a blowtorch directly on cement. cement still contains water, which expands greatly when heated and could cause it to pop significantly.
Make sure when your using the torch to keep the torch about an inch away. The torch is at its hottest point when you can see normal yellow or at the end of the blue flame.
I don't think it would be practical to do this in a real use case simply because that much heat almost directly on the bike/motorcycle/whatever would likely be too damaging to make the lock worth melting. Not sure, but I try to keep the lock as tight against my bike to just that reason.
Flame on concrete will make the concrete spall. The pieces that pop out are very hot and seem to want to stick to bare skin. At least wear eye protection, if you are not doing so. Could you try to melt the actuator with hi amp electricity, similar to the way you melted the lock shackle in an earlier video? Remove the covering from the shackle, ground it, then insert a screwdriver into the core, using it as the second electrical connection. Core melts, and gets hot enough to melt the plastic also.
It may have been faster to heat the core and then give it a few whacks with a hammer to move the locking paws. Or for a quieter approch, wrap a heavy chain on the lock body and use downward force to pull the body away from the shackle while it's being heated, the gooey plastic should give way.
I think it opened much earlier, you can see the shackle move out when you bump it around with the screw driver and chain, I think you just didn't use enough force
@@Herberthishful Yup, and i'm sure u can beat it with 5kg hammer too if u strike it from above while it hanging on chain bcoz what really hold the structure are just plastic..
I know you're not likely to see this comment anymore, but you should avoid heating anything with a torch directly on concrete. The heat can cause the concrete to explode due to rapidly expanding moisture (steam). Concrete always contains some moisture.
Perfect demonstration, (I liked seeing all of the working internals before the experiment began.) I think that having some spring-loaded lever between the shackle and the lock body could have halved the opening time.
The bottom of the core is rounded on one axis and snug with the body, so given that if the top and bottom of the core/actuator also fit snugly that would stop the core from rotating while just the plastic was melted. The bottom of the core would have to be melted before allowing rotation if my understanding is correct.
0:50 : Opened relatively quickly and quietly 4:43 : [VERY LOUD] POCHHHHHHHHHHHHHHHHHHHH. Or did you Think of some sort of battery-powered quiet pipe-heater or something but use this torch as a demonstration only?
Good plastic may be better than cheap metal (say zinc alloy) and it shouldn't be dismissed instantly, but yeah in this case it's not a good place for it.
Just a little tip. If you are going to heat items up with a torch it's not advisable to place them on a concrete surface. Concrete always contains some water and there is a good possibility that the concrete will explode when the water in it boils. Set your item up on a stand of some kind or better yet get a couple of firebricks to put the item on. Getting a piece of high speed concrete in your eye is never a good thing. As far as this being a practical method to defeat a lock on the street, I don't think so. It's noisy and time consuming and I think you would invariably be challenged by someone. If you did it at night, it would be even worse as the flame would appear out of place and draw attention.
An angle grinder would be easier to use and faster. I don't think anyone will bother melting a lock like this, especially because not every lock is prone to this method of attack, while almost every lock will give up to an angle grinder
@@bwood6337 It's a hell of a sight quicker though and it's been shown the and time again that thieves get away using angle grinders on a busy street by being just plain blatant. No-one tackles them and if they do the guy just says I lost my key. Who's gonna call him a liar with angle grinder in his hands! The only solution to more security is MORE locks so they go elsewhere!
Love your channel, keep up the great content, I picked my first lock when my key broke to my first apartment quite a few years ago, thanks to you. 1 critique tho... you'll get much better times getting thru the locks if you back the torch off a bit... the point of the flame has the highest temp concentrated into a tiny spot.
Given the mode of failure this would have applied equally to the New York Lock, as the lock body melted which would have allowed the rotation of the body regardless of the steel casing.
Any longer and you could damage the garage floor. Question Since the plastic has some obvious cutouts in it, can epoxy or other high temp filler be put in to help reduce the movement of the lock or the bolts? Was plastic used to lighten the lock or reduce corrosion?
I decide? NO, it isn't. You basically had to burn all the thing down to open it and it took a long time as well. And this was done in a specific, suitable, and comfortable position to do it. Locks in bikes won't give that chance. So nope, good try though Lawyer.
I was more surprised that your concrete floor didn't POP! (violently) due to its (natural) moisture content.. Direct flame on cement is normally a no-no. Ask me how I know ;o) Thank you for the video BTW. Gobble Gobble Gobble
Oh crap! I was afraid someone might ask :) It was dangerous :Oo I'll just say that it had to do with a women's prison, a inquisitive new guard, a tenacious cement shower divider and a Harbor Freight propane torch. Jumping to the chase.. I got a eye full of shattered cement. They now call me patchy and I"ll be out in 3 to 5. For God's sake, please keep this to yourself. Thanks!
Recently I needed a 12-volt heating element that would heat a copper tube to about 300 degrees Fahrenheit, so I strung a length of nichrome wire inside a teflon tube. Wrapped around the pipe, it worked beautifully. The teflon stands up to about 500F with no problem. The length and gauge of the wire and a fixed voltage source (12V lead-acid battery) serve to set a limit on the temperature of the alloy wire. I would bet that a heater of this type would work perfectly to melt the interior of that lock. It could readily be made to operate at a temperature that softens the plastic without causing it to smoke or combust. A brief test of the polymer's characteristics would serve to establish that temperature. To defeat the lock, just wrap the heating element around the lock, connect to a car or motorcycle battery and wait a few minutes. It would probably help to maintain tension on the shackle so as to force the lugs to move as soon as they're free to do so. Or, if using a tool to turn the actuator, one could maintain a twisting force on that object to encourage it to rotate the moment the plastic is soft enough. You'd just need a pair of pliers to hold onto the hot lock.
Great video. I think you are right in that if you had a tool that reached the back of the core the lock would have failed sooner. Surely the failure mechanism highlighted by melting the lugs out of place is also a failure mechanism for the new york version? aren't the locking lugs for that held in place by plastic?.
Particularly embarrassing for the more expensive version. The extra steel tube ads no security benefit since the core didn't move even with a screwdriver prying at it.
Could one also use torches to reasonably quickly heat up the shackle to remove the heat temper in a localized spot, then simply saw or bolt cutter the now untempered spot? Or is there too much metal there for regular handheld torches where the metal dissipates the heat too quickly not allowing the heat tempering to be removed.?
Yes, it is a problem and an easy entry for a low life with no skills but fire and brimstone I think is not a practical method to open up any lock in most situations. There is offcourse exceptions but regardless, they still should not be putting plastic in any lock, especially high end ones. Sad to see the sacrificial Kryptonite burn up though.😔🍺✌
I think we can consider this one as a security flaw, since you explained that the lugs fell down when the plastic melted underneath. So technically if you would direct the flame from the top of the lock you can open it faster than the method you tried ( Heating through the key lock). Plus there are "mobile" gas torches that i believe can achieve the same result. So plastic = No go! At least if its not protected like the New York lock.
Every meth user has several torches at their disposal and they are the ones most likely to steal your shit. Also most stoners have one to take dabs with.
10:49 - Technically, it _is_ a security flaw, since parts vital to the functionality of the lock are held in place by a thermoplastic. However, given how long it took to get the shackle off I would say that it's only a risk if one leaves their bike overnight.
I'd imagine the extra layer of steel would delay the melting somewhat. And if someone has the freedom/privacy to spend 10 minutes at your bike-lock with a gas tank and blowtorch, they'll be getting that lock open one way or another regardless. If you learn anything from reading up on (cyber)security and pen-testing; if someone wants to get into something badly enough, they will. All you can do is delay, or make the attempt as obvious as possible. (Like forcing someone to spend minutes with a blowtorch or angle grinder shooting flames/spark around and making lots of noise)
Considering the type of torch you used, I don't think it's too big concern though definitely a flaw. The other practical problem is the amount heat you have to use. This thing is a discbrake lock. You take a torch like that and have the discbrake in the line of fire, you may not be able to move the bike due to warping the rotor. At that point you'd better getting a crane and hoisting it into a truck and then taking your time to pick it where you end up taking it. They could probably use a better high heat plastic if plastic if that's route they choose to take. Also, this exploit would the same on the New Yorker. If the lock body melts, you could attempt the twisting exploit once it melts out of the steel housing, or you wait for the insides to turn to mush in about the same amount of time. If you can turn the lock body from the back faster than melting to the lugs, then it's an issue. Otherwise if it takes the same amount of time as the New York Lock and you trust the New York Lock, the Evolution should be okay.
I think it could be opened relatively quickly - just like any other lock - by simply using a smoke wrench. That one tool can open virtually any lock, and I think I could do it under a minute. Since all locks can be opened with a smoke wrench, then they all have a serious security flaw. (For those unfamiliar with a smoke wrench, they are also known as ox-acetylene torch with a cutting head.) I have one smoke wrench which can be carried with one hand. In the time it took to melt that plastic part, I could have cut the shackle and, most likely, could have split the lock body as well.
You mentioned this was a quiet method. I've been around plumbing torches although they're not as loud as a grinder they don't exactly whisper. Also if we're considering that much heat being used as a way to break off locks then enough thermite will destroy any pad lock being produced today.
Yeah I don’t think that’s an exploit given how loud, time consuming, bright, and nondescript it is. It’d be like saying “look at this locks exploit, if I put thermite on it, it’ll melt right off!”
Who knows what people will do? what is impracticable or (read) insane to one person is "normal" or "ok" with another. If you have a spare try soaking it in acetone, acetone melts ABS plastic (*lego) effectively. Jus be aware of the fumes. 3D printers often use a vapor bath to finely finnish printed items. Just a thought thanks for the video!
Actually, it's not a security flaw, but design flow - developers of this lock wanna make it lighter to user (velo- or motodriver) so he can easylly carry it in backpack or watevah. Heating this lock is impractical, couse you can destroy some stuff, that this lock safing (bike wheel, etc). On the other side, sledgehummering it upside-down can, probably, work - lugs just gonna grab in inside plastic. Again - if the placing of lock allow it. Also you can heat up the core, put the screw in and tore up all the core nuts, then rotate it. So much possibilities, if thief has a time to use them, but anglegrinder work's faster.
Considering the locks purpose this has no meaningful value as a test, the motorcycle it was in would be damaged enough, and the risk and very apparent attack high enough as to deter this, I would imagine a dedicated motorcycle thief would be better off just learning to pick it open.
For the streets I think it’s not practical but if someone is placing their bike into a basement of a flat or in the staircase maybe it can be done at night. Liquid nitrogen is working like charm on cheaper locks and you can carry it in a thermostat. Much quieter and quicker.
Would you kindly submit this video to Kryptonite? Because this flaw can be easily fixed (and ever retrofitted!): just make that plastic part from metal. E.g. machined aluminum: light and sturdy. The only issue that I see is seizing, i.e. steel and aluminum tend to seize up when in close contact, but perhaps that is solvable.
I think if you focused more heat on the steel body of the lock to create a oven inside the lock, it would be more efficient and also not melt the core. I also thought some pliers would be more easier. Instead of attacking the lock, attack the locking lugs, get them to move inside the plastic, which doesn't have to be as hot as you got it just to move things with more force. MAPP gas instead of propane would be great.
I think the lock put up a good fight, more than enough to defeat a lowlife with a blowtorch and screwdriver. I suspect you are not on Kryptonites christmas card list. Nice video thanks.
I think the problem is softening the plastic enough/deep enough to rotate the core while still allowing the bolts to travel normally. Not impossible, but it seems like it might take some practice. Seems like it would be faster to melt the bolt area like you eventually did. I don't think it's a weakness for a public area, but it could be an issue for a secluded one.
I have 2. And anybody can go to a home depot and buy a torch. Locksmithing tools are special order, and if you are caught with them without a license they are considered burglary tools. A torch isn't.
*I know the easy way to open this luck silently* *Grabs a torch that are loud as hell and a normal screwdriver* _there you go, no-one would notice that_
Would portable MAP gas torch work as well (like a single cylinder Bernzomatic)? I suspect this would work on locks that have an extra steel pipe inside ("New York" models), since they also have plastic guides inside, in which case it is a very serious flaw.

What about chemically attacking the plastic, injecting in a solvent?

However solvents are quite slow with plastics not to mind that some are toxic....
Fuming nitric acid will catch plastic on fire, could work but it's a little very very dangerous to do without safety equipment

Depends on the plastic. If it's ABS, methylene chloride will probably be fastest. But if it's PE chemicals aren't going to touch it.
Time is ok if you can put that thing into a bucket come back to it in an hour or two. Like if someone was parked at home or at work you could have time like that. As for the toxic nature of those solvents, it isnt like you plan on taking them home with you leave it in a garbage can nearby

I think if you need a plumbers torch it isn't an exploit any more than an angle grinder cutting it would be.
Try it with a creme brule torch and see if that works.
An angle grind cutting it is also an exploit.

Can it be done with an induction heater? Those are completely silent, only problem is a portable power supply.
Induction hears work only for steel and ferrous metals. Plastic is not affected, and heating the lock body red hot just for the tiny amount of heat going from the body to the plastic thing.. is quite inefficient.
Tiny amount of heat? Would you stick your dingus in a metal tube being heated red hot by an indution heater? I don't think so buddy. If you did you'd need a portable power supply each time you went to bed with a lady friend.
an butane torch will work better
and every bike stealing crack head has one of those.
A common portable cutting torch needs no external power and would cut anything that size laughing all the way. I use a medical oxygen cylinder for light weight on my portable setup and use disposable propane cylinders with an adapter which is easy to assemble from standard fittings. It's easy to carry in the field (I'm a mechanic.)
Torches aren't completely silent but a small tip isn't loud at all. Example quality kit: www.amazon.com/Harris-4403211-Acetylene-Cutting-Cylinders/dp/B01ES9CXVM You can find similar for less money.
Harbor Freight kits work but are prone to mixer tube fires in the cutting torch head and their o-rings I've seen (where the cutting head joins the handle) tended to crumble. You could replace those with Viton rings from a non-shit manufacturer.
Armature comment. Open area bike lock, no. Garage, alley or construction site yes.
A-1) Cut off the plastic with a carpet knife.
2) Using several eight by eight inch fiber glass mats over the lock for heat retention, pour diesel into shackle holes.
Diesel is far more destructive when it burns. Might use "sugar rocket" paste as well to get it going.
3) While burning the inside, use a chain or tool to pull the lock body away from the shackle.
B) Second approach, use a pipe and strap to hold a home made or Estes rocket motor over the key way and then insert a screwdriver. Again the fiberglass or even wet rags are put over the lock body to reduce noise, flames and people looking.
Thank you LPL for helping us make "a more informed lock purchase"
The hottest part of the flame is towards the tip. If the core is of a material that can be melted, play the tip of the flame towards the back and top instead. That amount of plastic should have succumbed within 90-120 seconds. Think of it as a brazing job.
Well he isn’t “Blow Torching Lawyer” for a reason
Brings a new meaning to a stolen bike being ‘too hot to handle’.
The plastic was supporting the metal locking parts. You melted the support. I think your screw driver had nothing to do with it opening. If you had mounted this in a big table vise you would have been able to pry the shackle open much easier. I think Fire Marshall Bill would recommend you wear welding gloves for this experiment.
If the thief "had" a hammer he could have tapped it out sooner. Also i think that the screwdriver would have worked better had he smashed it into the lock first with the hammer and then heated it. Now the whole lockbody just slipped away everytime he inserted the screwdriver.
But a big vise is not a practical Street tool
who needs a hammer or vice when a simple pair of channellocks would have done the job? the shackle is already held in place by the disc brake, so all you have to do is pull on the body when heating. could've had it open in a minute or two.
I'm not sure there would be anything left to nick.

Well to be fair, a plumber's blowtorch is something you'll be able to buy in just about any decent hardware store. Specialised lock-picking tools, not so much. So in that sense, a blowtorch isn't 'special'.
Blow torches are everywhere nowadays, especially with dabs becoming popular
It's not a blowtorch. It's a torch.
Yes it is common. You can literally get one in the camping section at Walmart. Also at any hardware store.
0:52 "Quickly and quietly" I think you should go check a dictionary for the definition of those two words.
Jokes aside, great video as always :)
I think you could of opened that faster than you did, i have a sneeking suspicion that you did not get enough leverage on the bottom of the lock fast enough you were using the screwdriver and tapping it rather than pulling with force, once you changed position and pushed with the torch it popped off easy, suggesting the plastic was well molten by then, im sure you would only need the plastic malleable to spin the lock ...
+Mikey N I agree.
Unlikely to be exploited in the field, but easy enough for Kryptonite to engineer (cheaply) around in the same manner as the New York Lock. Makes you wonder why they did this. The answer I guess is they figure most people will never realise the weakness. Keep up the good work.

Directing the heat directly onto the core would melt the core plastic housing enough to breech the lock. Very poor oversight on Kryptonite's part.
yeah. very poor oversight on their part... Kryptonite what were you guys thinking?
And using less heat so it could spread via the core.
I bet they were thinking "We could save money making this out of plastic"

+Nigel Tolley Perhaps, but I'm sure I could do this is FAR less time knowing what I know now. As far as lugging tools around, thieves regularly carry tools far larger and heavier.
Lmao. These bike lock companies must fucking hate the lock picking lawyer.
That's what I hate about plastic cores, the melting point of plastic, and it's just plain cheap, not durable. As far as this being practical, it would depend on the location and situation. The smells of burning plastic carry pretty far, and most people will look around to see what's burning. Also fire around a motorcycle could end up in one crispy critter. 😂 But obviously it works. Excellent video LPL.
A hydraulic bolt cutter is a silent beast. No sound, no wrestling with the chain to find a proper anchor for the bolt cutter, because the hydraulic one requires a lot lower force to operate and the force between jaws does not drop as soon as you let go, but maintains and only increases with each pump.. so it can swiftly cut anywhere, mid-air, without counter force.
A separate low volume rotary pump is compact and the cutter head is quite small and easy to reach tight spaces. (also does not matter much where it bites.. you can chop the whole lock in two)
And there are even hydraulic bolt cutter operated by electric drill. 2 seconds and 15mm shackle is toast.
The best thing is that these kind of tools are very expensive and highly specialized and not common.. so at least that's going for us defending against thieves.
But just as you do the overkill ramset gun tests, maybe you source such a hydraulic bolt cutter and do some videos with it.
I've played with such a tool from a buddy who's into big construction sites where such cutters are used to cut thick rebar ends (30+mm), and cut a bunch of things to my amazement.
yes. dont build locks that rely on plastic to hold any of the locking elements together.
for safety, never apply a blowtorch directly on cement. cement still contains water, which expands greatly when heated and could cause it to pop significantly.
Make sure when your using the torch to keep the torch about an inch away. The torch is at its hottest point when you can see normal yellow or at the end of the blue flame.
I don't think it would be practical to do this in a real use case simply because that much heat almost directly on the bike/motorcycle/whatever would likely be too damaging to make the lock worth melting. Not sure, but I try to keep the lock as tight against my bike to just that reason.
Flame on concrete will make the concrete spall. The pieces that pop out are very hot and seem to want to stick to bare skin. At least wear eye protection, if you are not doing so.
Could you try to melt the actuator with hi amp electricity, similar to the way you melted the lock shackle in an earlier video? Remove the covering from the shackle, ground it, then insert a screwdriver into the core, using it as the second electrical connection. Core melts, and gets hot enough to melt the plastic also.
It may have been faster to heat the core and then give it a few whacks with a hammer to move the locking paws. Or for a quieter approch, wrap a heavy chain on the lock body and use downward force to pull the body away from the shackle while it's being heated, the gooey plastic should give way.
Therocketman321 for a quieter approach, you could probably just use dynamite.At least the noise would be over in a fraction of a second.
Plastic or zinc has no business being inside any lock. Period.

@@Herberthishful Yup, and i'm sure u can beat it with 5kg hammer too if u strike it from above while it hanging on chain bcoz what really hold the structure are just plastic..
I know you're not likely to see this comment anymore, but you should avoid heating anything with a torch directly on concrete. The heat can cause the concrete to explode due to rapidly expanding moisture (steam). Concrete always contains some moisture.
Perfect demonstration, (I liked seeing all of the working internals before the experiment began.) I think that having some spring-loaded lever between the shackle and the lock body could have halved the opening time.
The bottom of the core is rounded on one axis and snug with the body,
so given that if the top and bottom of the core/actuator also fit snugly that would stop the core from rotating while just the plastic was melted.
The bottom of the core would have to be melted before allowing rotation if my understanding is correct.
Currently it's middle of the night for me and the torch is pretty soothing honestly.
0:50 : Opened relatively quickly and quietly 4:43 : [VERY LOUD] POCHHHHHHHHHHHHHHHHHHHH. Or did you Think of some sort of battery-powered quiet pipe-heater or something but use this torch as a demonstration only?
Anything that can get over 400 degrees could work.
"Quickly and quietly" eh? *Turns on blow torch* Yep, real quiet.
Good plastic may be better than cheap metal (say zinc alloy) and it shouldn't be dismissed instantly, but yeah in this case it's not a good place for it.
Well if I see someone on the street torching a bike lock for this long, I will most likely ask him:
"How may I help you ?"
Just a little tip. If you are going to heat items up with a torch it's not advisable to place them on a concrete surface. Concrete always contains some water and there is a good possibility that the concrete will explode when the water in it boils. Set your item up on a stand of some kind or better yet get a couple of firebricks to put the item on. Getting a piece of high speed concrete in your eye is never a good thing.
As far as this being a practical method to defeat a lock on the street, I don't think so. It's noisy and time consuming and I think you would invariably be challenged by someone. If you did it at night, it would be even worse as the flame would appear out of place and draw attention.
An angle grinder would be easier to use and faster. I don't think anyone will bother melting a lock like this, especially because not every lock is prone to this method of attack, while almost every lock will give up to an angle grinder
Yes but one of the points he mentioned was “relatively quiet” and an angle grinder is definitely not that.
@@bwood6337 It's a hell of a sight quicker though and it's been shown the and time again that thieves get away using angle grinders on a busy street by being just plain blatant. No-one tackles them and if they do the guy just says I lost my key. Who's gonna call him a liar with angle grinder in his hands! The only solution to more security is MORE locks so they go elsewhere!
Angle grinder is loud as fuck
Love your channel, keep up the great content, I picked my first lock when my key broke to my first apartment quite a few years ago, thanks to you.
1 critique tho... you'll get much better times getting thru the locks if you back the torch off a bit... the point of the flame has the highest temp concentrated into a tiny spot.
This took longer and more heat than I expected. Great video.
Given the mode of failure this would have applied equally to the New York Lock, as the lock body melted which would have allowed the rotation of the body regardless of the steel casing.
Meanwhile, the heat warped the brake disc to where the thief couldn’t push the motorcycle away 😂😂😂
you've hit the point !!!! great !!!!!
Any longer and you could damage the garage floor. Question Since the plastic has some obvious cutouts in it, can epoxy or other high temp filler be put in to help reduce the movement of the lock or the bolts? Was plastic used to lighten the lock or reduce corrosion?
Probably had it opened faster if you had pliers to hold lock.
I decide? NO, it isn't. You basically had to burn all the thing down to open it and it took a long time as well. And this was done in a specific, suitable, and comfortable position to do it. Locks in bikes won't give that chance. So nope, good try though Lawyer.
LPL, you should send it back to the Kryptonite company like that and ask for a refund. I can only imagine the response you would get from them.
Excellent. Thank You. Small question : is it plastic or metal into the ABUS Granit series ?
I was more surprised that your concrete floor didn't POP! (violently) due to its (natural) moisture content.. Direct flame on cement is normally a no-no. Ask me how I know ;o) Thank you for the video BTW. Gobble Gobble Gobble

Good afternoon, Mrs. Lawyer. Is your husband at home? "He's in the basement.... again"
I absolutely have no idea why I keep watching you.
Recently I needed a 12-volt heating element that would heat a copper tube to about 300 degrees Fahrenheit, so I strung a length of nichrome wire inside a teflon tube. Wrapped around the pipe, it worked beautifully. The teflon stands up to about 500F with no problem. The length and gauge of the wire and a fixed voltage source (12V lead-acid battery) serve to set a limit on the temperature of the alloy wire.
I would bet that a heater of this type would work perfectly to melt the interior of that lock. It could readily be made to operate at a temperature that softens the plastic without causing it to smoke or combust. A brief test of the polymer's characteristics would serve to establish that temperature. To defeat the lock, just wrap the heating element around the lock, connect to a car or motorcycle battery and wait a few minutes. It would probably help to maintain tension on the shackle so as to force the lugs to move as soon as they're free to do so. Or, if using a tool to turn the actuator, one could maintain a twisting force on that object to encourage it to rotate the moment the plastic is soft enough. You'd just need a pair of pliers to hold onto the hot lock.
+JamesG interesting idea. 👍

@@DukeChameleon 5 years of savings for a bike and a bike lock
Great video. I think you are right in that if you had a tool that reached the back of the core the lock would have failed sooner. Surely the failure mechanism highlighted by melting the lugs out of place is also a failure mechanism for the new york version? aren't the locking lugs for that held in place by plastic?.
How embarrassing. Plastic has no place in a security lock.
Particularly embarrassing for the more expensive version. The extra steel tube ads no security benefit since the core didn't move even with a screwdriver prying at it.
@@user46346bdtgry to be fair, it was a small screwdriver. Welding gloves or some clamp or something to that effect could have made it quicker
Sillimant the keyway isn’t big enough for a significantly bigger screwdriver. This is a disc detainer, not a regular keyway.
@@user46346bdtgry not everyone wants to carry 10kg of locks.
So Plastic is a way to save money and weight.
It does oviously reduce security though.
Enough time and disturbance for 50 cops to come or at least 2 or 3 Just notice from passing by , that's if the fire department didn't get there first
I'm curious if that same exploit is usable on the new York variant due to the mode of failure.
Could one also use torches to reasonably quickly heat up the shackle to remove the heat temper in a localized spot, then simply saw or bolt cutter the now untempered spot? Or is there too much metal there for regular handheld torches where the metal dissipates the heat too quickly not allowing the heat tempering to be removed.?
Try dynamite, maybe you will find an exploit.
Yes, it is a problem and an easy entry for a low life with no skills but fire and brimstone I think is not a practical method to open up any lock in most situations. There is offcourse exceptions but regardless, they still should not be putting plastic in any lock, especially high end ones. Sad to see the sacrificial Kryptonite burn up though.😔🍺✌
i think heating it from the top right at the shackle while pulling on the lock body would have worked much faster!
+Dave K. It's possible.
I think we can consider this one as a security flaw, since you explained that the lugs fell down when the plastic melted underneath. So technically if you would direct the flame from the top of the lock you can open it faster than the method you tried ( Heating through the key lock). Plus there are "mobile" gas torches that i believe can achieve the same result. So plastic = No go! At least if its not protected like the New York lock.
Yes, surely every bike thief carries a blow torch, a screwdriver and a 25 kg gas tank.
Every meth user has several torches at their disposal and they are the ones most likely to steal your shit. Also most stoners have one to take dabs with.
10:49 - Technically, it _is_ a security flaw, since parts vital to the functionality of the lock are held in place by a thermoplastic.
However, given how long it took to get the shackle off I would say that it's only a risk if one leaves their bike overnight.
Not only is your content great I love listening to your voice it's so calm and soothing. Keep it up.🇦🇺
No homo. ...right?
Why the F should these expensive locks have any plastic in them anyway?
Bad lock but not that terrible... it took tome time and blowtorch in the city would be suspicious...
Not really man because plumbers and handy men use them all the time. 30 seconds is fast not to mention this is quiet compared to a angle grinder
Thieves carry 3 foot long bolt cutters in a city.... A typical 14oz plumbers torch would be much easier to carry.
Thieves really don't care. A MAPP gas torch is not very big.
every street crack head has portable torches.
There might be other portable sources of heat except blowtorches. I can't name it right now, but I am sure there are.
The same flaw is present in the New York version too:
the plastic core will melt in the exact same way and the lugs will fall out of place.
I'd imagine the extra layer of steel would delay the melting somewhat. And if someone has the freedom/privacy to spend 10 minutes at your bike-lock with a gas tank and blowtorch, they'll be getting that lock open one way or another regardless.
If you learn anything from reading up on (cyber)security and pen-testing; if someone wants to get into something badly enough, they will. All you can do is delay, or make the attempt as obvious as possible. (Like forcing someone to spend minutes with a blowtorch or angle grinder shooting flames/spark around and making lots of noise)
Cost cutting at its absolute worst. Plastic in a lock?! Is Kryptonite affiliated with Mastercock by any chance 😝😂
Considering the type of torch you used, I don't think it's too big concern though definitely a flaw. The other practical problem is the amount heat you have to use. This thing is a discbrake lock. You take a torch like that and have the discbrake in the line of fire, you may not be able to move the bike due to warping the rotor. At that point you'd better getting a crane and hoisting it into a truck and then taking your time to pick it where you end up taking it. They could probably use a better high heat plastic if plastic if that's route they choose to take. Also, this exploit would the same on the New Yorker. If the lock body melts, you could attempt the twisting exploit once it melts out of the steel housing, or you wait for the insides to turn to mush in about the same amount of time. If you can turn the lock body from the back faster than melting to the lugs, then it's an issue. Otherwise if it takes the same amount of time as the New York Lock and you trust the New York Lock, the Evolution should be okay.
Plumbers torch isn't exactly quiet.
I think it could be opened relatively quickly - just like any other lock - by simply using a smoke wrench. That one tool can open virtually any lock, and I think I could do it under a minute. Since all locks can be opened with a smoke wrench, then they all have a serious security flaw. (For those unfamiliar with a smoke wrench, they are also known as ox-acetylene torch with a cutting head.) I have one smoke wrench which can be carried with one hand. In the time it took to melt that plastic part, I could have cut the shackle and, most likely, could have split the lock body as well.
It was open long before you actually opened it.
Agreed.
You mentioned this was a quiet method. I've been around plumbing torches although they're not as loud as a grinder they don't exactly whisper. Also if we're considering that much heat being used as a way to break off locks then enough thermite will destroy any pad lock being produced today.
Yeah I don’t think that’s an exploit given how loud, time consuming, bright, and nondescript it is. It’d be like saying “look at this locks exploit, if I put thermite on it, it’ll melt right off!”
Who knows what people will do? what is impracticable or (read) insane to one person is "normal" or "ok" with another. If you have a spare try soaking it in acetone, acetone melts ABS plastic (*lego) effectively. Jus be aware of the fumes. 3D printers often use a vapor bath to finely finnish printed items. Just a thought thanks for the video!
I think you had it opened within the first two minutes, all you need to do was to tap it harder maybe with a Mallet
You can always open a lock by taping it with a mallet
Actually, it's not a security flaw, but design flow - developers of this lock wanna make it lighter to user (velo- or motodriver) so he can easylly carry it in backpack or watevah.
Heating this lock is impractical, couse you can destroy some stuff, that this lock safing (bike wheel, etc). On the other side, sledgehummering it upside-down can, probably, work - lugs just gonna grab in inside plastic. Again - if the placing of lock allow it.
Also you can heat up the core, put the screw in and tore up all the core nuts, then rotate it.
So much possibilities, if thief has a time to use them, but anglegrinder work's faster.
Considering the locks purpose this has no meaningful value as a test, the motorcycle it was in would be damaged enough, and the risk and very apparent attack high enough as to deter this, I would imagine a dedicated motorcycle thief would be better off just learning to pick it open.
For the streets I think it’s not practical but if someone is placing their bike into a basement of a flat or in the staircase maybe it can be done at night. Liquid nitrogen is working like charm on cheaper locks and you can carry it in a thermostat. Much quieter and quicker.
Next time try MAPP gas to see if it is any faster
This was my thought too. MAPP gas could be easily concealed and burns hotter.
MAPP gas isn't available anymore. All you can get now is the "Map" stuff that's propylene.
Would you kindly submit this video to Kryptonite? Because this flaw can be easily fixed (and ever retrofitted!): just make that plastic part from metal. E.g. machined aluminum: light and sturdy. The only issue that I see is seizing, i.e. steel and aluminum tend to seize up when in close contact, but perhaps that is solvable.
I'm sure they already know about it. Plastic is just less expensive.
LPL. I have 3 questions for you.
1: how
2: when
3: why did you start lock picking?
I think if you focused more heat on the steel body of the lock to create a oven inside the lock, it would be more efficient and also not melt the core. I also thought some pliers would be more easier. Instead of attacking the lock, attack the locking lugs, get them to move inside the plastic, which doesn't have to be as hot as you got it just to move things with more force.
MAPP gas instead of propane would be great.
I think the lock put up a good fight, more than enough to defeat a lowlife with a blowtorch and screwdriver.
I suspect you are not on Kryptonites christmas card list.
Nice video thanks.
I think the problem is softening the plastic enough/deep enough to rotate the core while still allowing the bolts to travel normally. Not impossible, but it seems like it might take some practice. Seems like it would be faster to melt the bolt area like you eventually did. I don't think it's a weakness for a public area, but it could be an issue for a secluded one.
No special tools, he said... As if everyone just carries a blowtorch around.
I have 2. And anybody can go to a home depot and buy a torch. Locksmithing tools are special order, and if you are caught with them without a license they are considered burglary tools. A torch isn't.
....you don't?
@@taitjones6310 they are also a hell of a lot cheaper than a battery powered angle grinder
I wonder if a cordless soldering iron shoved into the lock would soften the inner housing with no noise and more directed heat? Then turn the core.
*I know the easy way to open this luck silently*
*Grabs a torch that are loud as hell and a normal screwdriver*
_there you go, no-one would notice that_
For a cheap "fix" maybe fill those spaces with jb-weld or similar high heat adhesive to resist the motion of turning?
bad guys don't work this hard
R
False
if hard work is what you mean by 5 minutes of heating it up for a bike that can be easily worth over 50k then i dunno man
Would portable MAP gas torch work as well (like a single cylinder Bernzomatic)?
I suspect this would work on locks that have an extra steel pipe inside ("New York" models), since they also have plastic guides inside, in which case it is a very serious flaw.
Yes
