@@EastImp That would mean you are planning on having a violent breakup or getting your key stolen. There is a video of a store owner who did something similar, to a burglar. He had a hallway with 2 doors. One door was unlocked but it shuts and locks after opening, no way out after that. Unless you're LPL.
I wish I knew this trick when my friend got divorced. It would have been priceless to see her struggling to get the key back out after dropping by to loot the place for a second time.
There was a design for fire alarms to keep the pranksters away. It locked the hand when you triggered the alarm and must be reset and opened by a policeman or fireman when they arrive. Cool design but i'm not sure why it didn't caught on.
Picking it would cause the driver pins to drop into the trap slots when the cylinder turns. So picking ensures a seized lock and using the old key ensures a trapped key. The picking would not give you proof positive evidence of who attempted entry tho
@@ChristopherGrey1327 if picked properly to avoid the false sets that happen due to the trap pins its still possible to get in and out unnoticed however its very pick resistant
You could also have this for a key where the new cut is lower than the old cut. This by having a T master wafer instead. So when the new key is inserted, both the key pin and T pin will be in the core, and the driver pin will be in bible (no trapping). When the old key is inserted, both T-pin and driver will be in bible, and thus trap the core. Same also works for mixed keys. For those locations where the new cut is shallower than the old cut, you put the T pin as driver, and normal masterwafer. And for those locations where the new cut is deeper than the old cut, you put the T pin as mw, and then a normal driver.

If one were to grind the construction holes into slots or ramps, would it be practical to make the lock so that one of the keys could only turn it in one direction while the other could turn it both ways? Such a thing might also be good for a challenge lock, since picking to the wrong shear line would give a very deep false set but not an open (since the lock would turn to the position of the construction holes but then get stuck there).

Jesus is more reliable. A burglar was slipping through the window of a house he was going to rob. Suddenly out of the pitch black darkness a voice said, "Jesus is watching you." The burglar froze, but when nothing happened he climbed on in and started creeping through the dark. The voice again said, "Jesus is watching you, and he is very angry." Grabbing his light, he cast the beam where the voice sounded like it was coming from. There on a stand was a large parrot. "Were you the one saying that Jesus was watching me?" he asked. "Yes" said the parrot, "and now Jesus is going to eat your ass." Hearing a noise behind him, he swung the light around and the beam caught the biggest, meanest looking Rottweiler ever born standing in front of the window. "Say hello to Jesus." said the parrot.
Interesting solution. I've never played with T(security) pins. I thought you were talking about Top-pins up until you displayed them. Neat trick. Not only does it trap the old key, but also does not unlock the door. :)
two years late, but from the inside you can pull the whole mechanism apart with screws that can be accessed from the secure/inside; that drops out the whole housing he's reassembling starting 7:17 which you can then disassemble with needlenose and that c-clip remover like he shows here
worth considering: key traps won't trap keys if the cuts are progressively deeper. we don't usually allow such bitting because without a 'wiper' (a high cut near the tip) pins can become stuck at the shear line. but if you did key it, say, 12345 or 11235 etc. your key trap might not hold the key.
Also the way you get it out, if you noticed the silver plate in the top of the driver pins shaft, I believe you remove that and remove the pins from the top to get them out, pretty damn sure anyways

Ahh, the master wafers stay above the shear line with the new key, but fall below the shear line with the old key. When they are below the shear line the t-pins can fall into the construction holes.
Okay, so I noticed my ex tried to unlock my door, and now the old key is trapped inside. This design indeed serves its purpose. However, it brings up a practical concern: not only how to retrieve the trapped key, but more urgently, how does the homeowner now gain access to their own house? Quite the dilemma!
just an idea: cannt you swap the Master Wafer for for a T Pin to catch locks where the old Cut is higher than the new one? for the new Key the T pin stays inside the Core, and cannot catch the holes, for the old key its pushed into the Bible and will catch the holes. Of course this method requires T Pins of specific length of what would be the master wafer (and likely a min difference in cut depth of 3 or 4), but it should work too right?
I floated a similar Idea however in my scenario we just create a reverse builder key situation. The difference being the lock allows the other person to enter. They will not know that we know they entered. Good for someone that is not a threat but we may want to catch them in a lie.
@5:08 , why are you using the new key to open the lock and change the pins? The only time you use the old key, is to show the pins not sticking out and getting stuck. Asking for a friend.
Yeah, he "skipped" a step -- the lock and key were both probably new, so the lock already had the pins for the "new" key. But, you still have to change the pins in order that the pin or pin+wafer meets the shear line for both keys (if you want to the old key to also turn the lock). IOW, you have to create/match shear lines regardless which key you use (old or new).
Have you ever tried to pick a Bramah lock? Bramah are the oldest lock company here in London (probably one of the oldest lock companies in the world). Their original 'challenge lock' was actually first defeated by an American over 200 years ago! The modern Bramah locks are still based on the original concept and they are fantastically well engineered locks. I'd love to see you attempt one.
Thanks for a wonderful video...I know little or nothing about locks...im trying to figure out how to re-key my door locks so one key will do them all without paying the $200.00 fee each time for someone else to do it. I watched this "KEY TRAP" video and am totally lost...but wondering...if the lock is permanently locked...how would you go about getting the od key out. Would you consider making a video on that...please and thank you.
You turned the old key anti clockwise!! That's quite rare. What if you turned it clockwise?? It would've worked like normal, and not trapped the key, right?!?
The Eminent Joshua E. Hrouda I noticed that too. Also don’t accidentally use a different kwik set key you have on your key ring when you get home and its dark outside.
It would trap any key that triggers the safety. And a bump key is very likely to jam as the odds of all the master wafers to be out of cylinder is very small.
Seems likes great idea as long as the the door unlocks by turning the key counter clockwise. But what happens if the door opens by turning it clockwise? I suppose you can modify the core for that.
You have to know what key they are going to use in the attempt so that the wafers line up with the shear line for both keys. IOW, you chose the new key, pins and wafers in tandem to "match" the old key.
Does this only work with the original key? I’m new to this whole thing, I would assume any key that fits wouldn’t just “engage the trap” it as it would still have to fall in to the parameters of the pin configuration. So if I legitimately used the wrong key on my door; for example my grandmas house key instead of mine it would act as a normal lock and do nothing.
This exact design would let any key that had every pin height the same as either the old or new turn, and trap any key that turned and had one of the lower pin heights of the old key.
I love your videos and don't even mind the adds, as I have a channel too and totally get it. But... when you have non- skipable adds, they shouldn't be 90 second long (a minute and a half), without the ability to skip. I absolutely refuse to sit through adds that long.
This is a Bad idea and a waste of time. I have seen other videos about this same thing. A new home owner should always have their locks rekeyed. But some do not! I know this by experience, a locksmith for 13 yrs.
Thanks for the acknowledgement and I'm glad I inspired you to work it out yourself. Your method is easier than mine where I modified the cylinder. Although I'm not sure they had T-pins when I did this in the early 90's. Now, with that said, it had me thinking of an easier way to remove the trapped key (especially if it's your only door). This is what I came up with, but it does require modifying the cylinder. And also require a little trial & error. 1. Find a small ball bearing that will fit into the construction keyholes. Measure the depth of the hole with the ball bearing in it. 2. Drill a very small hole (diameter of the above measurement) to the right side of the keyway that lines up with the bottom of the construction keyholes. 3. Place the ball bearings into each construction keyhole. 4. Now a thin rod inserted into the new hole (may need to be tapered) should push the T-pins up to the shear line, allowing the key to rotate. Now, this would also allow someone with the wrong key to still enter, but they would have to know what that little hole was for and have the right tool. You can also get a small sticker to cover the hole to make it less obvious. This is untested, but I think it would work. If anyone sees a flaw in it, let me know. Thanks.
I totally would have gone for that; but I talk to my booze sometimes. Nonetheless, this is an ingenious idea. Props for the great explanation LPL and Tom Collins thanks for the trapped key removal idea! It will be something interesting to experiment with once I grab some new locks!
Reminds me of a mail key for a package, "how they will leave a key in your mailbox to a different mail box so you can retrieve your package" it opens the door so you can get your package but the key stays trapped in the keyhole. How does that work?
It’s a different mechanism... much more simple. It’s a spring loaded device (similar to a safe relocker) that stops the core from turning back to the 12 o’clock position, thus preventing key removal.

I floated a similar Idea however in my scenario we just create a reverse builder key situation. The difference being the lock allows the other person to enter. They will not know that we know they entered. Good for someone that is not a threat but we may want to catch them in a lie.
Do you know where to get these pinss? and what is the item number for these pins? Vaughn BK Locks
@5:08 , why are you using the new key to open the lock and change the pins? The only time you use the old key, is to show the pins not sticking out and getting stuck. Asking for a friend.
Yeah, he "skipped" a step -- the lock and key were both probably new, so the lock already had the pins for the "new" key.
But, you still have to change the pins in order that the pin or pin+wafer meets the shear line for both keys (if you want to the old key to also turn the lock).
IOW, you have to create/match shear lines regardless which key you use (old or new).
So how are you supposed to get in if Marty's key is trapped in the cylinder? Boot the door?
@6:53 Thank you for pointing that out, I'm new to this hobby and that was my very first thought.
Have you ever tried to pick a Bramah lock?
Bramah are the oldest lock company here in London (probably one of the oldest lock companies in the world).
Their original 'challenge lock' was actually first defeated by an American over 200 years ago!
The modern Bramah locks are still based on the original concept and they are fantastically well engineered locks.
I'd love to see you attempt one.
Thanks for a wonderful video...I know little or nothing about locks...im trying to figure out how to re-key my door locks so one key will do them all without paying the $200.00 fee each time for someone else to do it. I watched this "KEY TRAP" video and am totally lost...but wondering...if the lock is permanently locked...how would you go about getting the od key out. Would you consider making a video on that...please and thank you.
Typically Marty always tried the backdoor.
It's about your kids Marty!
You turned the old key anti clockwise!! That's quite rare. What if you turned it clockwise?? It would've worked like normal, and not trapped the key, right?!?
The Eminent Joshua E. Hrouda I noticed that too. Also don’t accidentally use a different kwik set key you have on your key ring when you get home and its dark outside.
Nearly every Kwikset I've seen unlocks when turned anticlockwise.
unlike My door: turn anti clockwise to lock
can you trap a bump key like this?
It would trap any key that triggers the safety. And a bump key is very likely to jam as the odds of all the master wafers to be out of cylinder is very small.
What if you turn the old key to the right instead of to the left as in the video?
So then how do you make the lock usable again? Do you have to drill it out and replace or ??
I assume removing the top bible clip
@@ColdestLivewire What if that's the only entrance and lock to your home and you weren't inside at the moment of attempted entry?
Take it apart from the inside of your door
i relay would like to see you pick that lock :)
Im re-keying my apt now and this was what needed. Thanks!
so if u don't use the t pins u can have two different keys open the door right?
That's a basic feature of master pins, yes.
Hahaha, Damn you Marty, I said NO!. And No means NO! Good stuff. Thanks LPL
Why would you even keep the old key if you had swapped your locks. This is to prevent ex partners, etc from entering your house.
How do you untrap the key?
Damn that old marty keeps trying to get into my place
Seems likes great idea as long as the the door unlocks by turning the key counter clockwise. But what happens if the door opens by turning it clockwise? I suppose you can modify the core for that.
+Bobby Keyz It will not work without adding construction key holes on the other side of the core. I note this in the description. 👍
LockPickingLawyer sorry about that I know you always think if everything. I usually read the description too. Missed it this time.
So ¿this will ONLY work for the old versus new key, and not just any key someone tries?
You have to know what key they are going to use in the attempt so that the wafers line up with the shear line for both keys.
IOW, you chose the new key, pins and wafers in tandem to "match" the old key.
What if the deadbolt is on the left side? They'd still be able to turn the key clockwise and get in.
but they may decide to try and lock the door. That is when the trap springs.
perry mason would approve
Perry Mason's private detective would certainly approve.
Tough luck for old Marty 😁
Liked the lock picking lawyer thunk it was funny and like your videos
but now your stuck outside with marty
You really are a lawyer! Mini-legal pad!
how would you get into the lock if the key is stuck
can you post a video on how to remove the stuck key?
the "ex-wife" lock keying
And you live in a tenth floor apartment? Cliff repelling from the roof to the balcony? No balcony, steel door frame and one pissed off landlord!
Does this only work with the original key? I’m new to this whole thing, I would assume any key that fits wouldn’t just “engage the trap” it as it would still have to fall in to the parameters of the pin configuration. So if I legitimately used the wrong key on my door; for example my grandmas house key instead of mine it would act as a normal lock and do nothing.
It would also trap keys which had some pin heights from the old key and some from the new
This exact design would let any key that had every pin height the same as either the old or new turn, and trap any key that turned and had one of the lower pin heights of the old key.
This is like when they get a master counterfeiter to help make new money that’s on counterfeitable
Dammit, Marty! This is JUST like you. Classic Marty behavior...
I love your videos and don't even mind the adds, as I have a channel too and totally get it. But... when you have non- skipable adds, they shouldn't be 90 second long (a minute and a half), without the ability to skip. I absolutely refuse to sit through adds that long.
Question: How do you know his name is "Marty"???
Marty you son of a bitch!
Dirty old Marty...
This is a Bad idea and a waste of time. I have seen other videos about this same thing. A new home owner should always have their locks rekeyed. But some do not! I know this by experience, a locksmith for 13 yrs.
Could this be made so the trap is only activated on the first use of the new key? Like a construction key?
Why would Marty McFly even need to use that key? He has that DeLorean ya know.
"You will see that ole Marty was trying to get into your front door."
Damn...how did LPL know my name???
Your name is Christopher.....
Marty got busted!
Where is a good place to buy a small quantity of t-pins and wafers?
Small is relative. Try clksupplies.com
Thanks for the acknowledgement and I'm glad I inspired you to work it out yourself. Your method is easier than mine where I modified the cylinder. Although I'm not sure they had T-pins when I did this in the early 90's.
Now, with that said, it had me thinking of an easier way to remove the trapped key (especially if it's your only door). This is what I came up with, but it does require modifying the cylinder. And also require a little trial & error.
1. Find a small ball bearing that will fit into the construction keyholes. Measure the depth of the hole with the ball bearing in it.
2. Drill a very small hole (diameter of the above measurement) to the right side of the keyway that lines up with the bottom of the construction keyholes.
3. Place the ball bearings into each construction keyhole.
4. Now a thin rod inserted into the new hole (may need to be tapered) should push the T-pins up to the shear line, allowing the key to rotate.
Now, this would also allow someone with the wrong key to still enter, but they would have to know what that little hole was for and have the right tool. You can also get a small sticker to cover the hole to make it less obvious.
This is untested, but I think it would work. If anyone sees a flaw in it, let me know. Thanks.
and here i thought the name was fake and this was an idea over a strong drink...
Bret Mohler Real name. Not denying the strong drink part.
I totally would have gone for that; but I talk to my booze sometimes. Nonetheless, this is an ingenious idea. Props for the great explanation LPL and Tom Collins thanks for the trapped key removal idea! It will be something interesting to experiment with once I grab some new locks!
not "old Marty" ... it's "Biff" :-p
Marty might become a lot more dangerous once his key is stuck and he knows he is essentially caught.
I died at old marty
"[541] How to Make a Kwikset Key Trap, or detecting tampering"
Reminds me of a mail key for a package, "how they will leave a key in your mailbox to a different mail box so you can retrieve your package" it opens the door so you can get your package but the key stays trapped in the keyhole. How does that work?
It’s a different mechanism... much more simple. It’s a spring loaded device (similar to a safe relocker) that stops the core from turning back to the 12 o’clock position, thus preventing key removal.
i have opened one, and the way i bypassed it was using something to push the spring, so that way the key can return to the 12oclock position.
