hey that's the second Bulgarian lock for the week:) We've had this one on our apartment door like 10year ago. It is quite cheap. I remember a lot of torn pockets because of the long keys:) Greetings from Sofia, Bulgaria.
I was just thinking the same. It wouldn't take much to thread a couple of chambers in the core, add some more exotic pinning upstairs & downstairs, a few variations in spring tension, and it could really perplex a picker who doesn't have sight of the key or know about the unusual mechanism. Even without those modifications, unless an attacker already knew to expect this lock, they'd probably not arrive at the premises with a suitable length pick. It's a really interesting lock in any case.
Of course, but that's why you use an actual decent euro to start with, for example a six-pin which would give you the 12 you want, something with a decent manufacture quality, and as was said above "security pins and all the fixings" - in short, the good shit.
Precisely this. There's no way to have 12 pins in this junky Sonico lock anyway. Just mod an existing good euro cylinder with a similar style cam (can pass the key through it). Hard part would be to create a key that would be long enough. Still would be quite the sight
They should make a ridiculously long lock with a ridiculously long key. At least 20 pins. All of them different types of security pins. And double-sided, so there are actually 40 pins.
I remember that in my flat when I was a child we had lock with key that was more than twice the lenght of typical one. Almost sure that was Gerda made lock (Polish company) but have no idea on model. I do guess/recall though that it looked to have a shitload of pins.
I could argue that 99.9% of the people that would attempt picking this lock, would have no idea that this lock was inter connected making it very difficult to pick. I'd think the only way to get the driver pins into place would be to shim the bible and remove on the core installation. Anyway, good pick!
I feel like you'd start to get annoyed after awhile only to stick your pick in the back wondering why it's not opening only to realize there's more pins (if you pick is that long)
you'd also need really long tools to reach the second core so even if you figured out the secret you wouldn't be able to actually do anything with that information
LPL... WOW, love the lock design and how you lengthened your regular-sized pick to a custom extra-long pick to defeat this Bulgarian euro profile double-core. This “ordinary looking” lock appears to provide great picking camouflage. Would gladly carry an extra long key for this double-core security. LPL, thank you for sharing your security expertise.
Would have been harder to tension if the cores were split. I wonder if that is a realistic modification to increase the Lock’s pick resistance or if the actuator would allow for it... hmmm.
The Mauer GM redline has pins in both chambers and has split cores and makes it harder to tension, but being a dimple it is easier than this one as you have more room to tension it.
I think with a few minor improvements, like security pins etc, this could be a pretty good lock, not just because of the fact you need a customised pick.
I think what wasn't discussed is that it isn't obvious for a usual street-lock-picker is that he has to reach through to the other side, and would maybe give up, when he couldn't pick it from one side after the first 4 pins
I wouldn't say it's bad, just a couple mistakes, which are both still legible. "long core its pretty good idea" should be "long core is a pretty good idea" "thief is just dont ready" should be "thief is just not ready"
If installed externally, I suspect that keyway would be filled with dust and dirt from air blowing through it. Any tight tolerances would fail much earlier in that environment.
There was a euro cylinder lock of similar design in the 90's in Czech Republic made by Guard, a company later, or at that time aquired by EVVA, had six pins each side, security pins as well and you actualy needed two keys, one from the outside, the other from the inside as the profile was of course asymetric and trying for pick resistivity. And they were making it different lenghts on demand.
Hi there Lockpickinglawyer - I am a big fan of yours and really enjoy watching your videos, however, one thing I have never seen you do is putting the lock back together again after having gutted it. I'd be really interested to see that! Thanks and keep up the good work.
At last, a euro lock that puts up serious resistance to a snapping attack. Prior to this, the best that has been done for snap-resistance is a sacrificial section, but that leaves a core with only 2 or 3 pins so is much easier to pick. Better than nothing, but a combined snap/pick attack on 3 pins might not be beyond some thieves. This thing required decent picking skills even after a snapping attack. It's let down by the design of the core, but the concept is a good one. Tighter tolerances and some security pins would make this a winner. Next problem, that key is going to be a real pain to put in a trouser pocket unless you're wearing cargo pants. With sealable pockets, otherwise the key will jump out when you run. There is *always* a downside to a euro lock. It's inherent in the design.
It's cool to see you pick this lock, I just posted my first RUclips video featuring this same lock a few days ago. You picked yours quicker though. I was actually considering making mine into a challenge lock to send to you or Bill.
brett campbell If Bill spent as much time off camera as LPL to research the lock then he would probably pick it as fast. But sending him this lock with a mummified key, I doubt Bill would know to pick both sides of the lock.
I think the interesting thing about this lock is that you wouldn't guess from the outside that it was a super long lock and it's highly improbable that someone would have an extra long pick with them. I would put a spool and a super spring on each end though and then you would just bend your pick on the last pin.
Do you think there is any reason why more locks don't use security pins? It seems like a cheap and easy way to up the security level, but a lot of even mid to high security locks don't use them
We had similar lock when I was young. I think it was a different brand and to unlock it from inside you had to use normal size key but the long one from outside.
That is freaking crazy. I think with some better machining and more security features, that lock could be pretty formidable. Some counter milling, a variety of pins, and having the two cores have different bitting. I know with each core having different bitting, you wouldn't be able to open the lock with the key from either side, but most people only lock there doors from one side anyway.
Interesting lock. This sort of design would defeat the common breakaway lookout keys that cannot be backed out of the keyway. You could just push it all the way through.
So changing the bitting to be a little more aggressive and adding security pins and aggressive springs in the far back could make this almost impossible?
tip for them is to make the "core" like on a normal lock but that can only be tentioned from the back also if the front core is not picked the back can not moove to unlock but if the front is picked then it can freely moove only 90 degrees in either side ...
More importantly, it will defeat the snappers. Even those with picking skills good enough to attack the 2- or 3-pin core that's left after they've snapped a snap-resistant lock. Since snap attacks are by far the most common on euro locks, even with shitty cores this thing will prevent most thefts.
Can you explain to me what this lock is actually used for normal locks I understand rather they be bicycle locks etc, but these particular locks on this video I can't even picture what they're used for therefore they do strike my interest thanks. PS I watch you Bosnian bill and lot noob and sort of combine y'all's different techniques when it comes to picking locks which has helped considering I started picking locks long before RUclips was ever around back in the 80s again thanks for your interesting videos
With that key, you can get arrested for carrying a concealed weapon. Do not show this to the manufacturers marketing department, otherwise next gen of these locks the keys will be just carved to the machetes. "Longer key? You got it!"
i havent finished watching yet but that key looks just like a rake. its interesting that a lot of these "hard" locks really arent hard, its just overcoming the challenge of getting your tools to fit or adapt to the lock. it does work in the wild though when its a surprise to the attacker. edit: it looks like the pins are cut lopsided and uneven, low quality... it seems like this is the type of lock to make when youve got a ton of extra key pins to use. just throw em in there any which way and call it a high security lock with an impressively long key.
Odd that it has 3 pine on one side and 4 on another. This concept seems like it coule be very challenging: tight tolerances, counter milling/threaded pin holes, security pins, varied spring strengths, 5 to 6 pins on each side, and a highly pericentric keyway.
I wonder if it would be possible to create a mechanism with which you need to apply tension to both sides of the cylinder, in order to reinforce the idea of using two keys at once or one long one as opposed to being able to pick both cylinders separately. Reaching through the middle part in order to apply that tension would make things even harder.
Ooh! I'm gonna go to my car to get my long key and see if it's symmetrical like this, but I'm pretty sure it isn't. Also on the other side of the lock that my long key opens, you only use a short key.
If its outside of the protecting stuff (door) usally there is no mechanism what determinate what is the opening direction. If its in the door usally you can see what is the direction by the lock side (door opening), because 90% they are turned to opposite direction. In case of chain lock is usally turning right, because mostly pple are right handed and with right hand its comfortable to turn the key right. But any case if you didnt sure what is the key turning direction, you will know soon, because you wont get the tiny turnings of the core. You can use a pencil or marker to see its moved or not...

I've always figured the requirement of a very long key would be moderately effective. What intruder has time to modify his picks? :-) Given better pinning and tolerances, that idea could work to real advantage. For a while anyway, till longer picks became commonplace!
Make the cam much mode loosely connected to the cores and you'll have difficulties tensioning the second core via the first and having enough room in the keywas for a pick.
@LockPickingLawyer Can you explain why pick from front to back, instead of back to front, just curious lock noob. my logic I would start at the back and work forward, to not over set or bump anything in the front. Thanks

hey that's the second Bulgarian lock for the week:) We've had this one on our apartment door like 10year ago. It is quite cheap. I remember a lot of torn pockets because of the long keys:) Greetings from Sofia, Bulgaria.
You should re-pin that as a challenge lock and send it to BosnianBill as a thank you for the naughty bucket locks.😁
This
Make that a combo lock. One end is a dimple core and the other is a disk detainer core.
I was just thinking the same. It wouldn't take much to thread a couple of chambers in the core, add some more exotic pinning upstairs & downstairs, a few variations in spring tension, and it could really perplex a picker who doesn't have sight of the key or know about the unusual mechanism. Even without those modifications, unless an attacker already knew to expect this lock, they'd probably not arrive at the premises with a suitable length pick. It's a really interesting lock in any case.
Someone needs to make a 12 pin version of this! With security pins and all the fixings. I'd want to see that key lol
Of course, add fake cuts in the middle, so it looks like a 16 pin lock. :)
This would make for a truly brutal challenge lock. Throw in one of those ball-chain "pins" anywhere you please and you'll get hours of fun out of it!
Don't forget that this lock has poor tolerance so it wouldn't put up all that much of a challenge once you find a long enough pick.
Of course, but that's why you use an actual decent euro to start with, for example a six-pin which would give you the 12 you want, something with a decent manufacture quality, and as was said above "security pins and all the fixings" - in short, the good shit.

I think the key is overcompensating...
Greg K i like big locks i cannot lie
It's a good stabbing tool if needed.
For lack of security pins.
This could make an insane challenge lock
They should make a ridiculously long lock with a ridiculously long key. At least 20 pins. All of them different types of security pins. And double-sided, so there are actually 40 pins.
go all out, make it a 4 way key so there's 80 pins
Clever concept but spoiled by quality control. Nicely picked.
I love it, when you bring the ... strange stuff out!
That appears to be very weak bitting. Some deep cuts and security pins would make this one hell of a lock
It’s a seven pin lock, with only 4 pins worth of key differs. It wouldn’t be one hell of a lock either way.
Thats the longest key I ever saw! Thanks for the cool videos. You have god-like picking skills!
He does make it look easy. If I try it, I'd be on it for an hour minimum
@@forevercomputing an hour? Lol. Id probably break my wrist and get blisters too! And still not even be close! Thanks :)
Not as long as the kraken challenges on bills channel
I remember that in my flat when I was a child we had lock with key that was more than twice the lenght of typical one. Almost sure that was Gerda made lock (Polish company) but have no idea on model. I do guess/recall though that it looked to have a shitload of pins.

Anyway, good pick!
I feel like you'd start to get annoyed after awhile only to stick your pick in the back wondering why it's not opening only to realize there's more pins (if you pick is that long)
Gunga Dinn the standard trick is to cut a follower tube into 5mm or so slices and feed them in and out slice by slice from the central hole.
@@Luxe388 clearly needs a 3rd core with more pins
you'd also need really long tools to reach the second core so even if you figured out the secret you wouldn't be able to actually do anything with that information
Truly an artist. You make the difficult look so simple. Would love to see how you would design a lock to be pickproof.
He already did that (kinda). There is a way to modify a lock so that it completely seizes up when you try to pick it. Technically, that's pickproof.
LPL... WOW, love the lock design and how you lengthened your regular-sized pick to a custom extra-long pick to defeat this Bulgarian euro profile double-core.
This “ordinary looking” lock appears to provide great picking camouflage.
Would gladly carry an extra long key for this double-core security.
LPL, thank you for sharing your security expertise.
I was scrolling past when I realized yes, those keys ARE that long and knew I had to watch. Holy freakin cow
Would have been harder to tension if the cores were split. I wonder if that is a realistic modification to increase the Lock’s pick resistance or if the actuator would allow for it... hmmm.
Grouchy Ed I was thinking about this also. I think it could be solved by indexing the locking Paul on the key instead of the cores
The Mauer GM redline has pins in both chambers and has split cores and makes it harder to tension, but being a dimple it is easier than this one as you have more room to tension it.
I almost want to buy a lock like this simply for the novelty.
This was funny lock but I was disappointed that I didn't get to see the key in action at all.
I think with a few minor improvements, like security pins etc, this could be a pretty good lock, not just because of the fact you need a customised pick.
I think the main security is that most people won't expect this kind of lock and will be stuck picking one side over and over without success.
I think what wasn't discussed is that it isn't obvious for a usual street-lock-picker is that he has to reach through to the other side, and would maybe give up, when he couldn't pick it from one side after the first 4 pins
I Think, the long core its pretty good idea: cheap in production, and the trivial thief is just dont ready to this.
[sorry for my bad english]
Very, very few thieves have the skill to pick a lock.
@@AiMR throwing a rock at a window is a much more easier or a crowbar to pry a window open.
I wouldn't say it's bad, just a couple mistakes, which are both still legible.
"long core its pretty good idea" should be "long core is a pretty good idea"
"thief is just dont ready" should be "thief is just not ready"
If installed externally, I suspect that keyway would be filled with dust and dirt from air blowing through it. Any tight tolerances would fail much earlier in that environment.
Love the gutting when you can. I also appreciate the no-cut takes; I never feel like I've missed something.
Make one of these with some threaded chambers, some security pins and a bit more challenging bitting and this would be one hell of a lock!
What we need now is this, but 6 pins either side and an even longer key!
There was a euro cylinder lock of similar design in the 90's in Czech Republic made by Guard, a company later, or at that time aquired by EVVA, had six pins each side, security pins as well and you actualy needed two keys, one from the outside, the other from the inside as the profile was of course asymetric and trying for pick resistivity.

Such a strange beast of a lock that you tamed easily with your magic wand.😁👍🏻

Not dissing on bill but i dont think he would get it open, LPL would get it open probably pretty fast. would be cool to watch though.

I would put a spool and a super spring on each end though and then you would just bend your pick on the last pin.
File in kit always
seemed like the clicks were louder with this guy
david w pinkston I think it’s a combination of the microphone and the much heavier tension that LPL uses.
Very cool. Thanks for sharing
Great job picking brother as always and thanks for the review
We have locks that exceeds the possibilities of the average possible with keys that can inflict a lot of skin damage. That's Bulgaria for you!
I'm kind of disappointed in how easy it was to pick. It looked neat and promising like woah this gonna be a challenge.
Wow....
I love your vids.
Very cool picking..
Do you think there is any reason why more locks don't use security pins? It seems like a cheap and easy way to up the security level, but a lot of even mid to high security locks don't use them
Security pins add mfg cost and complexity.
(4:44) - Nice little dig there without actually calling anyone out.
Unusual lock. Good idea, has room for improvement.
should send you a lock like this without a key.
you would never get in until you took it apart.
We had similar lock when I was young. I think it was a different brand and to unlock it from inside you had to use normal size key but the long one from outside.
Please start operating the locks (key in and open lock) before you start picking and before you take them apart.
Thanks :-)
Why?
Tell me this is your first time watching LPL without telling me it’s your first time watching LPL 😂
The best thing this lock has going for it is that is is snap proof. Biggest issue with Euro locks.
woah, really good video quality on that zoom in
That is freaking crazy. I think with some better machining and more security features, that lock could be pretty formidable.
Some counter milling, a variety of pins, and having the two cores have different bitting.
I know with each core having different bitting, you wouldn't be able to open the lock with the key from either side, but most people only lock there doors from one side anyway.
It should be easy enough to cut keys with bitting that mirrors each other. Then you just have an inside key and an outside key.
Interesting lock. This sort of design would defeat the common breakaway lookout keys that cannot be backed out of the keyway. You could just push it all the way through.
Liking the Bulgarian locks! Still hoping for a codkey industries padlock pick!
Nice strong clicks coming from the lock. Very noticeable with headphones in
Why is he picking the Lock upside down?
So changing the bitting to be a little more aggressive and adding security pins and aggressive springs in the far back could make this almost impossible?
That key can be used as a survival tool also, fire wood anyone.
Really loving your videos. You've inspired me to really get in to lock picking. I look forward to the next episode of the Naughty Bucket Chronicles!
Settwi I don’t think there are any locks left 😀. My advice to LPL, another visit to bill, and this time bring a gun 🤣
Lol eBay addiction, I was going to buy one of those too!!!
Would have been nice to have seen the key in the lock opening the lock before you picked it: . 😄
Why?
It took him about a minute to pick it, which seems like a long time until you remember the length of the lock.
tip for them is to make the "core" like on a normal lock but that can only be tentioned from the back also if the front core is not picked the back can not moove to unlock but if the front is picked then it can freely moove only 90 degrees in either side ...
So... I watched this after a tonsillectomy whilst on Hydrocodone pain medication and... this shit looked so damn wild
Will u try to pick the plug upside down ? That is the top pins below ?
white finger tension! respect lpl
Wow, what a simple and elegant idea ! That will complicate things for the cocky pickers ! Oh .. nevermind ..
More importantly, it will defeat the snappers. Even those with picking skills good enough to attack the 2- or 3-pin core that's left after they've snapped a snap-resistant lock.

I'm always surprised by how fast you pick your locks.
Wow, nice work.
With that key, you can get arrested for carrying a concealed weapon. Do not show this to the manufacturers marketing department, otherwise next gen of these locks the keys will be just carved to the machetes. "Longer key? You got it!"
i havent finished watching yet but that key looks just like a rake. its interesting that a lot of these "hard" locks really arent hard, its just overcoming the challenge of getting your tools to fit or adapt to the lock. it does work in the wild though when its a surprise to the attacker.
edit: it looks like the pins are cut lopsided and uneven, low quality... it seems like this is the type of lock to make when youve got a ton of extra key pins to use. just throw em in there any which way and call it a high security lock with an impressively long key.
Great job and video like always
Great video as always!
When you get around picking again I challange you to pick the similar Mauer. It has not a solid cam like this one but an internal and external key.
I just ordered one 😀
I was hoping you'd get a Mauer GM Redline, but this is close enough for now.
Clever idea and plenty of room for improvement eh!!!
Odd that it has 3 pine on one side and 4 on another. This concept seems like it coule be very challenging: tight tolerances, counter milling/threaded pin holes, security pins, varied spring strengths, 5 to 6 pins on each side, and a highly pericentric keyway.
Yes challenge lock, put in security pins and change the keys so that you have a right side and a left side keys
Looks like it could be easy to rake. Could you try this? greetings
Jeez those "clicks" are more like cracks
I wonder if it would be possible to create a mechanism with which you need to apply tension to both sides of the cylinder, in order to reinforce the idea of using two keys at once or one long one as opposed to being able to pick both cylinders separately.

If its outside of the protecting stuff (door) usally there is no mechanism what determinate what is the opening direction. If its in the door usally you can see what is the direction by the lock side (door opening), because 90% they are turned to opposite direction.
In case of chain lock is usally turning right, because mostly pple are right handed and with right hand its comfortable to turn the key right.
But any case if you didnt sure what is the key turning direction, you will know soon, because you wont get the tiny turnings of the core. You can use a pencil or marker to see its moved or not...

Certainly innovative, could be a real pain if there were some nasty deep spools and T pins in there.
I've always figured the requirement of a very long key would be moderately effective. What intruder has time to modify his picks? :-) Given better pinning and tolerances, that idea could work to real advantage. For a while anyway, till longer picks became commonplace!
Make the cam much mode loosely connected to the cores and you'll have difficulties tensioning the second core via the first and having enough room in the keywas for a pick.
If you had this length key on ypur ring you would soon be in the market for a a replacement.
Also this design probably is very easy to bump.
If you came across this in a door and never saw the key do you think it would take you longer to figure out?
Who would expect that coming up to a door? They'd be so confused after picking the first half.
Wow, the feedback on those rear pins must feel weird.
If those keys were just a little bit longer, they could be used as a set of crutches!
That would be a tricky lock to pick if you didn't know the key goes all the way through the lock
Judging from the wear on pin 3, I'd bet it was also facing down.
I wonder where is gets this wacky stuff!! Awesome!
I know, right? I didn't expect to see anything from my country here. And now in almost a week Bosnian Bill and LPL post Bulgarian lock videos.
I can't imagine that thing in my pocket.
Is that a key in your pocket or are you happy to see me?
Why would a lock like this not require tension on both sides? 😕
Wouldn't a rake do the job even faster?
turgsh01 Can you imagine raking that distance without snapping or bending a rake. Would take a deft touch I think...
@LockPickingLawyer Can you explain why pick from front to back, instead of back to front, just curious lock noob. my logic I would start at the back and work forward, to not over set or bump anything in the front. Thanks
Wouldn't this get gummed up with crud blowing through it from the pressure difference inside and outside the house?
Impressive lock.. if you are into length.. ;-)
Can you rake this?
nice clicks on this one
I am from Bulgaria and I have this kind of cylinder. Mine has a long key thats used from the outside and a short key thats used from the inside.
