U need to get a patent

It's nice showing off the prototype gear however this isn't any better than a conventional pin and tumbler lock. It doesn't do anything to protect against comb picking, at most meaning it takes abit longer as each attempt requires a reset from the test position. Although the master key pins make it easier rather than harder to pick by creating multiple valid combinations, increasing the odds of successful picking. It also is highly vaurnable to corrosion due to the tripling of the number of moving parts which makes it inappropriate for outdoor use.

Why they still have vulnerabilities to this day? Because nobody will learn to pick a lock. Whatever for? A thief usually does not give much of a damn about you knowing that you've been robbed. Unpickable locks are stupid. There, I said it. You want your lock pickable, especially when in a situation where its destruction also destroys something else that's probably actually valuable. Like your car door. Or an antique chest or what have you. A lock is there to deter someone who just happens by and gets a tad too greedy or nosy for a moment. Someone who absolutely wants in will not waste hours to learn lock picking but will go buy a bolt cutter for 15 bucks. The people who learn lock picking are the lock smiths who have an interest to get their customers into wherever they locked themselves out of without causing more costly damage.

A vulnerability someone else pointed out is that the watchdog pin could be vulnerable to kinetic attacks so a combined method could be used, if someone connects the inner and outer cores they could knock it upwards then pick the other pins like normal furthermore I suspect the cammed surface might allow new kinetic attacks for the watchdog pin specifically, for example rotating the inner core breifly yet harshly to launch it up. A way to fix this would be to add a more limiting mechanical linkage, for example imagine a piston engine, the inner core is the "crankshaft", a connecting rod links an off center spoke attached to the rest of the inner core to the "piston", or watchdog pin, so only once it's pulled fully into the "cylinder", or outer core by the inner core turning far enough will they both be able to rotate. The machining might be a pain but it shouldn't be too bad. As a bonus since it's moving down instead of up and displacing a driver pin it wouldn't be possible to wedge the driver pin upwards somehow then turn the inner and outer core back into alignment, perhaps by an attacker adding friction between the inner and outer core so when turning it back the outer core continuously puts pressure in the reverse direction, keeping the driver from falling. I think you greatly underestimated how vulnerable it'd be overlifting attacks, based on what you showed there you wouldn't need to lift the stacks completely beyond the outer core, just high enough that the wafer stacks overlap the shear between the outer core and the body instead of between the inner and outer core. You did talk about that later in kinetic attacks but the solution you gave seems limited and limiting. You could limit the potential travel distance of the pins without needing the user to compress the springs completely by having a narrower section that can fit the springs but not the pins. For preventing decoding attacks why add additional master pins of variable length when you could just vary the length of the driver pins directly? Not a vulnerability, it just seems like an unessesary complication.

Watched all of your 3 videos. Your way to explain things with simple cardbord cutouts is incredible! Also i am impressed about the genius way to improve the lock. Instead of adding a New part i would rather use different driver pin length.

awesome video concept would suggest you make videos around 30 mins long or under 10 mins for the algorithm to show more people the video

Please keep this project going, I'm sure that there are a lot of people interested in your work that would be willing to actually use it if it achieves total picking protection.

imagine the lock of your combined with the second lock of ,,works by design,, and the lock from ,,Stuff made here,, together. I don’t even know if this would work. You 3 should work together to make the most secure and complicated lock of all time.

Insurance companies is the reason tbh

The secret to an unpickable lock it to make it impossible to get a pick to access the pins. If the keyway makes it impossible to get a pick to lift the pins then it become unpickable. LPL has some examples of extreme keyways on at least 1 of his videos. A simple 2 piece core can easily have a profile that you can't get a pick in. As far as your lock goes I suspect that it could be vulnerable to a comb oversetting all of the pins, rotating and then letting the pins collapse. Without knowing exactly how your lock works it may also be susceptible to being picked backwards and then a spinner used to rotate it before the pins collapse.

I'm curious if you used security pins as master and driver, because I didn't notice it in the manufacturing video. I think that they can make impact attacks less effective. Regardless, nice lock!

When i think of a unpickable lock i think of something with a reverse sidebar when you put tension on the core it binds the sidebar and all the pins feel loose and if you use a key the pins are aligned at the same time and the sidebar retracts even though you didn't turn key because the side bar is pulled inside (look up yuema or kwikset smart key locks) oh and the springs for the pins would be stronger than the ones pulling the sidebar

2:53 What you're calling a mid-core looks extremely similar to the Master Ring on a Mogul prison lock, although you're implementing it differently. In a Mogul, the change key engages the normal center-most shear line. Inserting the master key locks the inner core to the master ring and engages the outer shear line. Both shear lines turn the same cam that operates the door lock. I don't know if you were already familiar with the Mogul prison locks, but it's an strikingly similar piece.

The first 3 minutes really helped cement my understanding of why pins "bind" - excellent video!

I am concerned about the potential for over-lifting, but you did a wonderful job here. As I'm sure you know, the LPL is widely considered the final KZbin authority on lock quality.

Yes, this sort of wafer-stack design is probably the most achievable approach. You can actually find expired patents with this type of design. I wonder if any lock manufacturer would consider making this into a real product? I've been pondering this issue ever since the time I had to stow all my worldly possessions in a storage unit (for about a month, seven years ago) and was so worried I could hardly sleep.

Try Comb picking but lift only so high that the first viable shear line of the wafers is used at the mid-core and shell interface shear line.

Quick, someone get a bottle of Laphroaig to summon LPL.

I would be curious to see the lift and rap attack tried with a vibratory tool instead. It may still be able to jump the master pins. It's not a vector I would expect someone attacking the lock off the street to take but it'd be interesting to see

Though you solved the lift and rap attack, I believe the design is still vulnerable to a kinetic attack. Particularly a bumping attack done in combination with a plug spinner. In this attack unlike normal bumping tension would not be applyed before striking the pins, rotation only begins after the pins have been hit. The plug spinner would allow the rotation of the core fast enough to reach the clocking. While it may be possible to perform this attack with two separate tools such as a snap gun and plug spinner, the timing required makes that highly unlikely. A new tool where the two are combined would be more plausible. As this requires new tooling to be designed, and other locks would be similarly vulnerable, I don't believe this detracts from the security of your design. Further the innovation of new tools to attack your design shows how well you have guarded against traditional attack vectors. Well done! I hope to see this project continue, your innovation is great to see!

Yo, bro. I really want to be your friend. I am familiar with locks, and think I could help you with your trials. I'm really excited to see a commercially available, unpickable lock be created. Furthermore; I would love to be involved.

Great videos ! But is really bothering that your camera is ever so slightly out of focus !

Genius. Get it made in metal and send to lpl. 😊

Another small engineer channel to collect

Lets hope there are no unpickable locks. Howelse are you gonna get in if you loose your key? Destroy the lot? Millions misplace their keys every day, what then? lol

this has way too little views

Definitely keep on this. I'm digging the actual in depth research. Also I wouldn't mind having a go at picking this bad boy if you're ok with it!

It aint unpicakable until LPL says its unpickable

Locksmith here, there are locks that are EXTREMELY hard to pick. The issue is price, people aren't willing to spend a hundred dollars or more on a basic lock. Not to mention installation, servicing, etc. The more pins, the more something can go wrong. Just one master pin can greatly reduce the pinning arrangements, I could make a "unpickable" at my shop. The issue is you wouldn't buy it, you might think you would. But you won't. People don't even want to pay for basic security pins, they WILL NOT pay for some hyper advanced lock. We sell Abloy locks, extremely high quality obscene pick resistance for a few hundred. And we also sell commercial master locks with pretty trivial pick resistance. We sell dozens of Masters a month, I've not seen a single Abloy sell in the last 2 months

Very cool video, subbed and looking forward to more videos from you

Great work. More and more locks today are digital. These can be made very secure relatively cheaply (even is many are over priced). However in most cases both the electronics and the mechanical systems, including the mechanical key bypass are all easily exploitable. I would like to offer to work with you on this if you are interested. I am an electronic engineer.

I am very impressed with your understanding of locks and hacking techniques. Most people are unable to think in a complex way that is not based on their beliefs. Very nice.

Just so you know, the design of your lock is very similar to the design of a person named Andy Pugh (who is under that name on KZbin). Just much simpler. I thought you might be interested.

just needs a way to tension the outer rotating cylinder

3minutes in and this is the best simolified visualisation i’ve seen on why cheap locks are pickable, regardless of “pick-proofing” techniques such as the use of spools and such.

Really cool lock and also a great video!

As long as it's mechanical, it can be circumvented, i am very curious as to what you come up with, but there will always be a way through

Good work.

Damn, you only have 3 videos and 500 subs? This video was recommended to me and I only noticed halfway through, I would have never guessed that, great job and I would love to see more!

I designed an unpickible lock but i cant make it because im not an engeneer and i dont have any tools for it.😢 Can you make it? Please

Very innovative! I have seen a few people who have shared very similar ideas to this, and I do think there is a lot of potential with it. One major issue I will say (and you touched on it) is if this lock was mass produced, the large amount of masterpins/wafers would cause the lock to fail and get jammed up often, especially in situations where the lock is exposed to the elements. I would be interested and it would be really cool to see how well a lock like this would hold up after a few years in the field! ___ I know it's frustrating to see the same technology in locks, especially when they can be bypassed so easily in many cases. That being said, it's been this way for longer than just the last century and a half, but actually for a few thousand years when you consider warded locks, lever locks, and even the anchient Egyptian locks. This technology isn't going away, especially in today's age that has defined standards and rating for locks and door hardware that has been established and set over the last century and a half. The best we can do is raise the expectations of the quality and effectiveness of the locks that are already in production. You would be amazed at how good tolerances alone can make a lock very difficult to pick... but on top of the good tolerances, if it has a paracentric keyway, high-low bitting, and security pins (especially when there is matched milling in the plug), the lock becomes nearly unpickiable in the field when done right. I personally would love to see the overall standards of locks in NA go up. It is clearly a major issue when companies like Master Lock know about their security flaws and choose to ignore them since they know the general public is unaware and they will make more money that way... I don't want you to think I'm saying that it's not worth the effort you are making... by doing what you are doing, you are helping to educate the public on locks and the security flaws of the locks that exist here currently. Also, if you were to produce these as commercially available locks, you should do it as your own high security company (similar to what Bowley and other major lock manufacturers have done). This is typically how lock companies have developed and grown over the last century. Even masterlock was known for better quality locks a few decades ago, and even produced their own high security lock (#19). As other high security companies were gaining success and masterlock had already captured the basic comercial market, they discontinued their high security line and refocused their development on cheap low quality locks since that's where the money was for them and they didn't care about the reputation of having cheap low quality locks. This is why they don't fix their security flaws today.

Оригинальная идея это хорошо. Пластиковая модель великолепно. Но рабочий образец из метала покажит все плюсы и минусы замка на испытаниях.

You might want to replace one of the wafer stacks with a solid pin, if combed, you only need to bring the pins up half way to open it. Also it's starting to look like an sfic design with extra wafers

I'll have a go 😁👍

Really nice clean design. In the vein of a few other locks that have been proposed of late focused on separating the testing from the setting. I think the two parts of your design that make it less commercially viable than it would appear are as follows. 1) In its current form it is a one way lock so you can not lock the bolt using the key. limits the applications 2) is the size of the core, Making new hardware to fit a new cylinder is not a commercially viable thing to do at this point in the lock business.

I got you a real world test for that cylinder. Had a call for what I thought was a simple lock out. Turned out to be a domestic situation where Deputies had trespassed a Male from a residence. My Customer a Female that owned the home didn't have the key as the Male had hid it or something. The Deputy informed me the Male was pretty much a career criminal. So I get a Security Release form signed by the Female and ask for proof of property ownership. Pick the entryway and was requested to replace all locks with ones she had purchased herself. They were Defiant branded and I did my best to explain that they would not keep the Male out seeing as he was proclaimed as a career criminal. I did the install correctly and got a call around 1am that the Male had made entry into the home and thought to have damaged one of the deadbolts. The residence was suppose to be vacant. I told her to contact the Sheriff's Department and that I would come back during daytime hours. The Deputy that responded during the night seen no forced entry. At this point I'm thinking the Male shimmed the entry knob but the dead latch was functioning before I left. So there is only one place in our town that sells Defiant sets and that's Home Depot. Considering he was able to continue entering the home after she locked it back up I concluded he went and purchased a lock set that had the same key bitting. Possible he had a bunch of old KW keys and one just happened to operate the lock due to the horrible tolerances. Finally after all of this I have convinced the Customer to purchase two Schlage B60s and have me do a custom pinning job on them. I'm fairly certain this Dude will continue to invade the house. I do have some Gnarly custom made Security pins as well as anti bump kits. Sad thing is this is going to be a hefty charge even with the Customer purchasing the locks. If I had a couple spare commercial deadbolts I'd just use them. I just thought I need to check and make sure the hinge pins are inside the house. Eventually when those B60s are installed I know its gonna be destructive entry constantly.

I just watched all three of your videos, very entertaining and I'm really impressed at how simple your design is. I'm looking forward to see more updates!

Excellent video 🔏👍🌐☮️

Fantastic work. I would love to try picking it 🔓

Would having different spring force on each pin stack make vibration stacks more difficult?
