3D Printing – High Security Key
- robbedpeter 5y agohttps://youtu.be/avwt39uHDOQ https://youtu.be/avwt39uHDOQ LPL needs to get a 3d printer. Then again, by the time you've printed a single key he'd have picked dozens of locks, lol. Thanks for this link! Having a parametric reference could be useful, I have family that collects and resells stuff that needs to be opened or picked (estate and bankruptcy and business closeout, all legal. )
- zxcvbn4038 5y agoI was going to say, he has proven time and time again that anything with a keyway can be picked quickly and discretely by anyone with a little knowledge (and the sometimes the right tools). Really amazing watching him work but it freaks out my wife when she watches his videos. I have one of the crap locks from Amazon he featured on my storage locker. One night someone tried to break in but spent so much time trying to take the door off the hinges that they had to run away empty handed. Bet they would be kicking themselves if they knew the lock could be jiggled open in under two seconds!
- b9a2cab5 5y agoYou should see his unpickable lock video [1] where he goes over all the approaches he tried to pick said unpickable lock. Super interesting stuff. [1]: https://www.youtube.com/watch?v=qV8QKZNFxLw https://www.youtube.com/watch?v=qV8QKZNFxLw

- piquadrat 5y agohe has proven time and time again that anything with a keyway can be picked quickly and discretely by anyone with a little knowledge (and the sometimes the right tools) While it is fascinating to watch LPL make short work of almost every lock, I think it is safe to say that his lock picking ability is on a whole other level compared to even a competent burglar. If LPL spends more than 30 seconds with a lock, it's probably going to be fine.
- formerly_proven 5y agoIf you only watch these videos you might walk away with the impression that it is that simple for him - just walk up to the lock, pick it in 30 seconds and bingo - but in one of his earlier videos he pointed out that before recording a video he practices opening that particular lock until he can do it reliably.
- causi 5y agoDepends on the lock. He has several videos that go from unboxing to picked in a few minutes without break.
- dagw 5y agoTrue, but only for lock designs he's already familiar with.
- SamBam 5y agoSure, but 90% of the locks people use are the same few locks. Any padlock or door lock you can get at a hardware store is one that a good lock picker has experience with. Your point is valid for certain high-security situations, though.
- 542354234235 5y agoI’d say even beyond that. Bosnianbill, another incredibly talented lock pick said that LPL is by far the most talented lock pick he has ever met. Given that less than 2% of all burglaries utilize lock picking or shimming a door or window, it is a virtually nonexistent risk as soon as you step up your lock above the basics. Unless you are directly targeted, no one is going to pick their way in to your things.
- jsjohnst 5y agoI’m far from being a skilled locksmith, but every friend that’s offered to have me try their lock so far, I’ve had opened in under 60 seconds with nothing more than a tension bar and a rake.
- shimonabi 5y agoThat's not plastic, is it? Not many people have access to a metal powder 3D printer.
- sigmaprimus 5y agoABS and PLA probably would be too soft but some locksmiths use soft material with a skill call impressioning. Most modern home FDM printers can reach temperatures high enough to print with poly carbonate which would work fine as a key. PolyC is prone to warping but on such a thin print I doubt warping would be an issue.
- Mashimo 5y agoPC with fiber should warp less and might be stronger. But I'm not sure if it has the same accuracy or any other downside.
- KZerda 5y agoDepends on your need. For a key you'll only need/want to use one or two times, plastic will be able to hold up just fine. If you need something more durable, there are a number of 3d printing services that'll print whatever you want in metal without any questions asked. Desktop sintering printers are also getting cheaper and cheaper. They're still several thousand dollars, but that price will only come down now that patents are expiring and people are starting to be able to work on the processes to get them more resonable in cost.
- doctoboggan 5y agoJust an estimate but I think this key in steel would be less than $50 on shapeways. EDIT: I just uploaded the model to shapeways to get a quote and this key is: $26 for steel $44 for aluminum $75 for brass The brass would probably have the most dimensional accuracy. I have a small company that sells custom jewelry, and some of my customers want steel rings. They usually cost me around $15. On possible downside is that due to cooling shrinkage steel only has about 5% tolerance. This can be accounted for in the 3D model. What I usually do for jewelry is order the ring in 2 or 3 different sizes and then choose the one that fits best. In terms of this key, I am not sure how much 5% error would affect its functioning.
- CobrastanJorji 5y agoIt's worth pointing out that this is specifically the Medeco "M3". The newer generation, "M4", advertises itself as resistant to 3D printing, which it accomplishes by adding a tiny moving shuttle pin inside the key itself. Thre's no reason a 3D printed key can't have a hole for adding a little spring and a pin, but it does mean that a 3D-printed key probably won't work right off the printer, which helps defend Medeco's main selling point: making it hard for the average person to easily acquire a copy of a key.
- jjeaff 5y agoIs that really the extent of their claim? "Hard for the average person to obtain a copy"? Seems like a regular key stamped with "do not copy" could meet that threshold.
- CobrastanJorji 5y agoWalk into any store with a key-copying vending machine and, hey, new key. But none of those machines are equipped to cut Medeco keys, partly because it's a little more expensive to make a machine the measures and cuts them, and partly because of IP. The idea with Medeco is that you give one of these to your AirBNB guests or a building maintenance worker or something, and if you get your keys back, you can be reasonably confident that they didn't make any copies. You can't be 100% sure, of course, but the average mall machine or even locksmith probably can't help them. An authorized Medeco agent will want documentation that you have the right to have a key made (you're the owner and not a renter), and they will of course happily charge you rather more than the mall kiosk to make a copy.
- SamBam 5y ago> you give one of these to your AirBNB guests or a building maintenance worker or something, and if you get your keys back, you can be reasonably confident that they didn't make any copies. This seems to be a fairly useless reassurance. If you trust your AirBnB guest so little that you think they might reasonably make copies and distribute your key to unsavory people, then just the single key floating around out there is enough to compromise your security.
