French person here, these locks are extremely common in France, for most you don't need to push the handle to turn it. Anyways thanks to you I got to see the mechanism inside them, and I've been wondering about it since I was a kid
im locksmith myself & i can tell u i dont see this type of "overlay lock" often ( i google translated it so correct me if its not called like that in english ) i guess they are rare outside of paris, fyi overlay locks are used in supplement of the regular european barel & there is sometimes 2 of em + the barel in my region overlay locks are made mandatory if u want the assurance to reimburse u after a burglary. Im not parisian so i wont assume its the same everywhere in france =)
@LockPickingLawyer: I have one of these on my front door, fitted about 25 years ago. One drawback is that solitary wasps seek out holes just about the size of the keyway to lay their eggs in. They then seal up the keyway with "paper". Ours was out of commission for a year before I could get it working again, but fortunately we have two locks and the other one is a standard Yale-style.
Honestly though, a bunch of wasps flying out of a lock when you try to pick it has got to be the best deterrent I've ever heard of. That's the stuff of nightmares.
@@namelessminionveinreaver3763 sadly, they'd just be baby wasps, if they've hatched at all. But did give me a fun idea. A person could go collect a large amount of bees and contain them inside of a treasure chest, then leave the treasure chest outside with just a Master lock securing it, then set up a bunch of cameras and wait for someone to get interested in seeing what's inside....

These keys remind me of the "Changeling" key from "Star Trek: Deep Space Nine". In the episode "Vortex" (S01-E11), an alien shows Odo a special key made out of Changeling material. When the owner wishes to use the key, it morphs into the shape needed to open the lock. The key was cylindrical, with several vanes radiating out - very much like the keys in this episode! Presumably, the Changeling key offered added security by morphing into shape only for its actual owner, but this was not fully explained. This key secured something most precious - the alien's daughter who was locked in a stasis chamber.
54 of the now decommissioned Nuclear silos used 2 cheap Chicago double sided locks. They both were 10 ft. apart or so and took 2 people to turn them to activate the missile. You can see this at the Titan Missile Museum near Tucson Arizona south on interstate 19. They sell duplicates from the original keys there. You can probably get them from their web site. They are just Chicago double sided keys.
Sadly it's slightly easier than a 25 pin Master Lock because it a 25 pin Master Lock that would actually take forever to pick cuz you have to figure out which pin is binding out of the 25 options you have Master Lock if you read this comment please make this happen it would be sleepy the most pick resistant lock you've ever made
I love these videos. I have no idea what you're actually doing to pick these locks but it's fascinating watching. 🙂 The brute force and gallium methods are hilarious tho'!
Basically, you lift the two pins until the point where they are separated hits the shear line of the lock. The shear line is where the lock's core is able to turn in the lock body. Lockpickers take advantage of slight manufacturing defects where some pins bind up before others to defeat the lock. One pin might be bigger than the others or the holes for the pins might be drilled very slightly out of line. If you want more info search for "MIT Guide to Lock Picking" for basic info. And don't pick *any* lock you don't own or have the express permission of the owner to open. A Burglary charge isn't something you want to deal with.
This was pretty common in France as a secondary lock. Especially when the main lock was not a 3-point lock. It was cheaper to fit 1 or 2 of those to add extra locking points than replacing the entire door. With 3-point locks becoming more common over the years, these secondary locks have progressively disappeared. But you can still find them on old houses and apartments, or on secondary wooden buildings (barn, tool shed, etc).
It occurs to me that anyone with a cordless drill and a common screwdriver bit could bypass the lock entirely in seconds. Why are the fasteners that hold the lock assembly in place on the unsecure side of the lock again?
@@TestECull Notice how long the cylinder is? It's designed to be screwed to the door from the inside. Notice when LPL showed the "press-then-turn" button there are four holes for mounting. The extra long cylinder goes through a little hole in the door, where the keyhole will barely jut out of the door's outside surface. So to unscrew the mechanism from the outside, an attacker needs to know precisely where the fasteners are, and drill through a thick door panel to reach them. That will take time and increase the probability a thief will get caught.
hey bud, this was absolutely amazing, and honestly a nice way to demonstrate a tubular lock since they’re usually not (non-destructively) guttable. thanks for sharing it! request! perhaps a video on the most interesting (or just your favorite) keys in your collection? I’d watch the heck out of that!
I find your presentations of great interest from a mathematical point of view. How the locks are designed and picked. Also, what amazes me is that you have specific tools for every small task. Very interesting. You must spend a lot of time studying these locks. You can write a book as well. Thanks
These types of locks or other ones that stay in position we mostly have on the backdoor. The frontdoor always has a lock that falls back in place, but might have one of these located at the top of the door as extra.
Considering that this is a form of tubular lock and all the springs and driver pins are the same, could an impressioning tool be made for this lock? I also like how you had to undo four screws, then three, then two and then one.
Impressioning tools for locks like this DO actually exist... Even though you definitely need to be an "authorized locksmith" or law enforcement or know someone to have access to one. Impossible to get otherwise and BTW I'm French and live in well... France ! Fun fact: These impressioning tools are literally called "umbrellas" in French (Parapluie) !
rack and pinion mechanism, the full lock is two complete 360 revolutions, usually with an additional 180 from the internal knob, if it has a through keyway, you can leave the key in on the inside effectively blocking the outer keyway, and then picking from the outside is stymied because you can't get to the pins. the advantage is that unlike wedge latches that can be forced., the bolt is a solid lump. there are more solid side racked bolts too, this being the current standard in France. it's a shame fitting euro sections is not possible as the design hasn't cganged since about 1900
What a coincidence! Yesterday I noticed a key like that at work and was wondering what it was. Now I know! It was locking an old safe packed with useless tapes from the 70/80's
yeah, pretty much all entrance door locks over here are built into these relatively solid blocks, just as solid as the doors we use, so you can't just force the door open from the outside without a tool, that's the main thought behind it. It's rarely such a big, hefty bolt like this, but the lock frame is always solid
I'm sure it's easy to spot wear or witness marks on the pins with a flashlight so each pin can be "sight picked" and and an easy impression or jig can be made to use for a key because it looks easy to see how far the pins need to be pushed in
I had that kind of key for my apartment in Paris. One day I broke it inside the lock and the locksmith just drilled a hole in the key, and used a screw to remove it from the lock. Then I was able to use a spare key to open. Because the key is round it was easy to drill a hole in it.
So, the lock is basically surface mounted on the inside of the door with just a relatively small hole drilled through the door for the keyway / cylinder to go through the door. I could see a certain advantage to that in that it does not weaken the door as much by putting a large hole in it like with the deadbolts in most US homes. Another advantage would be that it wouldn't be that difficult to modify it so that it could be located in the center of the door with bars that went to each side of the door, thus acting as a deadbolt on each side OR even multiple deadbolts on a single side. Maybe the lock itself needs a bit of improvement to make it LPL-proof, but since your typical burglar is going to try to kick in the door, it does hold some promise in that aspect since it looks like it could be modified fairly easily to have multiple bars activated at the same time.
Security companies should start playing around with the idea of a lock that needs to be picked a lot, rather than be hard to pick, yea? If someone can get through it anyway, make it have a higher minimum picking time?
Pick-resistant locks do actually exist: Take the Abloy Protec for disk detainer type And the Fichet Sans Souci for lever type There are so many more very pick resistant lever locks... In fact safe/vault locks in Europe are actually lever-type.
Pick resistance is a lock that is difficult to pick. Which again, would be the current model of security in locks. I literally meant a lock that is made in a way you have to pick it multiple times, regardless of how resistant it is to picking. Like the lock in the video. Which has very little pick resistance, yet still took near a minute due to needing to be picked SIX TIMES.
@@finchwaddledog5026 LPL is wrong, most people lock these by turning the key twice, so he would need to pick this 14 times, not just 6. I don't see a thief standing in the open trying to pick this for 8-9 minutes while it's really obvious what they are doing...
I've recently acquired 2 different models of WB padlocks. One of them looks like it might be from the 1800's. Old as dirt anyway. The older looking one says property of DOUGLAS GUARDIAN WAREHOUSE CORP. Both are 5 standard pin locks. The old one has NO warding in the key way and I still can't pick it. I was able to shim it open and rake it open but I've yet to SPP.
Someone watching this video after the lock was disassembled might think those are parts from a 5 chamber revolver. Interesting design, even though it is not a secure lock.
Particularly nice and great picking. I'm curious if this lock would be susceptible to the plug spinner "attack"? Just sitting here watching all of your tubular lock pick vids. Very exciting!!! But yeah, if you could put this question to the test, that'd be great. Thank you. I appreciate your videos.
I have a Fichet coming that looks similar but it's key is tapered a bit. It probably functions in the same way. That is a very cool lock & key. Would be tricky with security pin's in it.🍺😎
Saw this design and couldn't help but think of the old peanut butter cup ads... "You got your kinda-sorta Bramah key in my kinda-sorta Chicago lock" "You got your kinda-sorta Chicago lock in my kinda-sorta Bramah key"... lol
Kinda makes me think how good a normal lock would be if you just put multiple pins around it so it had to be picked multiple times before it could open. you could even do different security pins so someone couldn't expect what was coming up.
Hi Harry, Interesting lock and pick, could possibly be made by the same company that makes locks for the French safe Co. Fichet. or Fichet Bauche I think. The locks are called Monopole, and there are variations, but certain similarities to your lock. Would love to see the key machine that produces these keys! Regards, Brian.
9:33 The pin stacks are obviously different height - it appears that the driver pin is always the same and the key pins have pretty big length differences thanks to key design. You could probably decode the lock simply by measuring how deep each pin can be pushed and then cut a suitable key if you don't want to pick it. With threaded pin holes, sharp spool pins and high tolerances, this would have been much harder to pick. Interesting lock, nonetheless.
French here: Theses types of locks are common on the entry door of apartment (the whole building door) Mine has a spring inside of it that push the key outside. Pretty hard to oppen with the key, so I think that without the key, it would be a torture
I went to Paris in 2005ish and the apartment we stayed at had a lock like this. I never knew what they were and I have been trying to figure it out on and off ever since then. Thank you so much for finally bringing an end to my quest. I'm having a hard time with Google searching "central lock", though... Any idea where I could pick one of these up?
idea from a recent video (im on an LPL binge): since you mentioned its like a tubular lock, maybe a design like this, but with a giraffe key style entryway? would require a special pick and otherwise be infuriating to pick probably
Can I just confirm something? If you partially picked this lock (ie, only one of the six pickings completed, so it has only turned one sixth of a complete revolution), would it prevent the lock being opened by the key? It seems like the 12 o'clock tooth of the key is slightly taller than the others, and so you wouldn't be able to insert again once that channel is misaligned?
Looks like it, but then if you use the key, you can't get it out except when the full rotation is completed. If you're on the inside, then depressing the button and turning it a little will stop anyone from the outside using a key as the lock body will be disengaged. That may leave it vulnerable to under-the-door methods.
Sees the run time of the video. Thinks "this must be a complex pick". Turns out the picking is very easy. It's the amount of screws in the dismantle process that takes up a lot of time.
Is there any way to bypass the need to pick multiple times? If not, wouldn't replacing those pins with pick resistant spools or serrated ones have effectively 6x the normal efficacy, as any increase in pick time is effectively multiplied 6x over? It seems to me that the design in question, in addition to having a key which looks incredibly cool on your key ring, could be modified to make something truly frustrating to pick, without TOO much of an increase in cost.
Thanks very much for the reply! I love the videos, they are very helpful, very detailed (especially around concepts and the "whys" of things), and thoroughly entertaining. Thanks for sharing them, and keep up the great work!

I went to Paris in 2005ish and the apartment we stayed at had a lock like this. I never knew what they were and I have been trying to figure it out on and off ever since then. Thank you so much for finally bringing an end to my quest. I'm having a hard time with Google searching "central lock", though... Any idea where I could pick one of these up?
Beautiful lock well explained. If I ever run in to one its nice to know how to get it open nice spp'd.great lol thanks for sharing buddy. 🌟⭐🌟⭐🌟😎
Technically the mechanism is a rack and lantern wheel. Since the last screw is exposed, couldn't you undo it and rotate the entire cylinder?
Omg if i have secret hidden areas in my home I would love to have these locks to put on those hidden doors.
There is one on Ebay : www.ebay.fr/itm/Verrou-Marque-Central-Paris-Idem-Pollux-5-ailettes-A-Pompe/202804096784?hash=item2f3810ef10:g:XCIAAOSwO0VdrKfD
I think you should put a reassembly on the video! this will be awesome!!
idea from a recent video (im on an LPL binge): since you mentioned its like a tubular lock, maybe a design like this, but with a giraffe key style entryway? would require a special pick and otherwise be infuriating to pick probably
we had one of these on the garage door
Have you had much to do with Lockwood locks they are pretty popular here in oz
I think I have seen these keys in french movies, were they use these keys for jailhouse doors.
Matrjoshka of screws 😁
Is it longer the barings, the easier it is to pick the case here? 😅
Can I just confirm something?
If you partially picked this lock (ie, only one of the six pickings completed, so it has only turned one sixth of a complete revolution), would it prevent the lock being opened by the key? It seems like the 12 o'clock tooth of the key is slightly taller than the others, and so you wouldn't be able to insert again once that channel is misaligned?
Looks like it, but then if you use the key, you can't get it out except when the full rotation is completed.
If you're on the inside, then depressing the button and turning it a little will stop anyone from the outside using a key as the lock body will be disengaged. That may leave it vulnerable to under-the-door methods.
The gear mechanism is a rack and pinion
I think that mechanism may be called a cam
What a very cool key
I love Russian Dolls and screws.
Where did you get that cool little light form, can't find it anywhere
Thats a cool lock
Ive gotta know where you got that little. Light
The lock surrendered and unlocked
For a guy with so fine picking senses he's quite clumsy with screwdrivers.
Sees the run time of the video. Thinks "this must be a complex pick". Turns out the picking is very easy. It's the amount of screws in the dismantle process that takes up a lot of time.
Is there any way to bypass the need to pick multiple times? If not, wouldn't replacing those pins with pick resistant spools or serrated ones have effectively 6x the normal efficacy, as any increase in pick time is effectively multiplied 6x over?
It seems to me that the design in question, in addition to having a key which looks incredibly cool on your key ring, could be modified to make something truly frustrating to pick, without TOO much of an increase in cost.
You would need to improvise a specialty tool. Not difficult, but picking is so easy, why bother.
Thanks very much for the reply! I love the videos, they are very helpful, very detailed (especially around concepts and the "whys" of things), and thoroughly entertaining. Thanks for sharing them, and keep up the great work!
impressive lock are there any german style locks built like that by the way good job I enjoy watching you work
