[1299] Unpickable Locks From Stuff Made Here

this is the lockpicking lawyer and the video you're about to watch is the culmination of a series of events that started about six months ago that's when shane at the excellent youtube channel stuff made here posted a video build of an unpickable lock that video which i will link below also challenged me to open it i obviously accepted because the lock is here but shane wanted to improve his design first and by improve he seems to have meant completely redesigned from the ground up because what i received was the original lock and a second lock which bore no internal resemblance to the first and i have to say i had a great time with these because both mechanisms are to the best of my knowledge completely original and in my opinion quite good fortunately for me though shane doesn't have a lot of experience with locked defeat methods so there were a few minor oversights that i was able to exploit however each of the issues i found can be fixed with very little effort which would result in formidable lock designs before we pick these i want to explain what i'm going to do so my actions don't look too cryptic that will require some reference to the internals but if you want a detailed look at what's inside you need to check out the stuff made here youtube channel and all the appropriate links are below the first lock this one looks something like this on the inside when you insert the key the pins in contact with the key will lift these upper pins that are shown in gold those pins then lock into place and rotate until they're in contact with this fin there are gates in the fin and only if these upper pins are in the correct position will they pass through notably however when that test phase occurs when those upper pins encounter the fins they are no longer in contact with the key pins that's what makes this unpickable in theory what i'm going to do is lift all of the upper pins as far as they will go lock them in place rotate them until they're in contact with the fin and then drop them down until they fall into their gates it usually takes a few attempts for it to work but the method seems to be reliable second lock is even more complex than the first it actually has two cores attached with an internal connecting rod if we look at the back we can see the bottom core the top core and a connecting rod the sheer line that matters is the one on the upper core which we can't access to tension it's behind this area of the lock by the time that upper core actually turns the bottom core is offset by about 45 degrees which means you can't move the pins that's why this lock is at least in theory unpickable put differently when you can access the pins you can't tension the lock and when you can tension it you can't access the pins i'm going to try to get around that by inserting a thin piece of metal between the door and the lock housing then slide it up until we're over the top of that upper core and then pull down which should tension the upper core once that happens i should be able to pick this as i would a normal lock there are two other potential vulnerabilities the first arises from a combination of this core rotating 45 degrees in either direction until it seizes up and the tail piece being misclocked by about 45 degrees when we pick you'll see why that makes a difference but i think you'll get a chuckle when you see how they interact the second vulnerability is decoding and we can do that because all of these upper driver pins are the same length a tool can be fashioned to lift all the pin stacks to the stopping point fully compressing the springs that's an indirect way of measuring the key pins which would allow us to cut a key i did not create that tool because i had another way to open this but that's something that used to be common before manufacturers started varying these lengths okay i have been talking for too long the jig that shane sent me to pick these in is way too big to fit on my desk so we are going to mount these up head down to the garage and try to open them okay we are down in the garage both locks are mounted in this mock door and the frame is secured to my workbench we're going to start with the newer of the two locks and discuss a vulnerability enabled by the fact that this core will turn about 45 degrees before it seizes that creates an issue as the lock interacts with the deadbolt now under normal circumstances a deadbolt that is fully extended can't be pushed back into the door however if we turn this core as far as it will go it's just enough to disengage the anti-retraction mechanism that's something we can certainly take advantage of while the door is locked all we need to do that is something that will turn the core and something pointy like the tip of my pocket knife so i'm going to turn this as far as it will go then use the point of the knife to walk the bolt back might as well let them know we're here next we are going to attempt a picking attack though certainly not a traditional one we discussed it upstairs but what i'm going to do is attempt to slip this between the door and the housing so we can tension the upper core pushing this in will do damage to the door however i don't think it'll be a lot of damage and i don't think it'll be very noticeable because it'll be on the bottom however i will show you the damage after we're done the hard part will be getting this into position so let's do that now i am pushing the tool against the door so it doesn't deform okay i might have it but the only way to be sure is to pull on these pliers and see if the pins are binding there we go click out of one little click on two nothing on three little click on four little click on five one two another click on three click on four nothing on five i don't feel anything else let's see if we have this open okay now let's work on the older lock once again i discussed the theory of what we're going to be doing while we were upstairs however it's a little bit harder in practice first we need to lock it okay i'm going to use this pick to lift all the pins to their highest position and when i release these i'm going to be tapping on the housing with this mallet it allows for a little bit more control as the pins come down and it increases the chances of success from about one in every 10 times to one in every two or three i think we've got it okay folks let's bring all this stuff back upstairs i will show you the damage underneath and we will sum everything up okay folks we are back upstairs and i'm going to briefly address how to fix each of the exploits i demonstrated but first let's take a look at the damage to the door it's certainly noticeable once the lock is removed though much of the damage is covered by the lock and the part that isn't is probably obscured because it's underneath the bulky housing frankly even if i saw that i'd probably attribute it to sloppy installation and not to an attack while we're looking at the door note that shane welded both of the hinge pins probably to stop me from popping the pins and declaring victory and i've got to say he did the right thing because i definitely would have done that moving on to the locks the issue with the first lock can be fixed easily by decreasing the angle of the fins so there's no slope for them to rest on frankly a reverse rake would probably be advisable with the second lock the first exploit can be fixed with a slight modification to this moving tail piece re-clocking that cutout by about 45 degrees there are about a dozen ways to fix the picking exploit and deny access to the back of the lock but when i told shane about it he precision machined a back cover which is probably the most expensive solution but certainly one that works so i hope you all enjoyed this shane excellent work on these locks and thank you so much for sending them my way to everyone else that's all i have for you today if you do have any

Comment from Stuff Made Here:

Super interesting exploits. Lock picking lawyer is one sharp guy 🙇‍♂️. Thanks for putting all that time into them to educate me on how to make them stronger! I think I smell something in the wind though. Wait yes I know that smell. It smells distinctly like lock V3.......

Here is the video of them being made on StuffMadeHere's channel

The ringing of doorbell is like the ultimate snub. I crack up every time he does it.

[u/goodguygreenpepper]

Looks like high praise for the mechanisms but some small oversights in the execution that made picking them doable, though in both cases it was with non-standard methods.

He did recommend how to fix these issues though. Sounds like he'd consider them extremely solid locks if those issues fixed.

StuffMadeHere is probably one of the best new YouTube channels in the last few years. Really excellent.

In case Stuff Made Here's video doesn't make it into the top of r/videos too.

I have been waiting for this video for months.

A ten minute LPL video, you know it is going to be a treat.

He cracked these pretty easily but those are still some really good locks. Imagine if he didn’t send him the blueprints he would have a hard time with the second.
