(picking 607) Inside a digital lock: decoding, gutting and how it works

[@Potti314]

A souvenir from China from a good friend of mine. These digital locks are easy to decode but I never looked into one ;-)

[@funkeyfastdrawmonkey1483]

Very cool to see the inside of one of these 🔒🔒 I have an old Sturdee brand one from 1982. Thankyou for the informative video my friend

[@Potti314]

Nice, you have to show us your lock - never heard of "Sturdee" before. Cheers buddy :-)

[@pestilentz6106]

I always enjoy watching you decoding locks. The most impressive part was that you were able to put it back together again so that it worked. I probably would have sent the parts back to the factory!

[@Potti314]

I was worried that putting it back together would be difficult but it turned out to be almost easy - despite the fact that the little spring needed some convincing words to stay in place ;-)

[@pickbeard2690]

I also have one at home, never looked inside of mine. I don't have to now you have done it for us 😎😎👍🍺 Thanks for sharing 😘😘

[@Potti314]

Cheers and thanks for watching - have fun with yours :-)

[@PocketWomen]

A very interesting video. Thanks for the gutting, rarely do we get to see inside a lock like this.

[@Potti314]

Cheers, I was really curious myself ;-)

[@jojozelaya7203]

Oh, my gosh! Thank you!! I bought 8 of these some 35? years ago. I bought all of same combo for 6 of them but ran out of that in the store and got 2 with a different combo. I forgot one of the odd ones but you mentioned the combination on your video and it worked! they were made by Gorin no. 10036 with a Japan stamp. 6 have black buttons, and the others are chrome colored. Mine don't have a half-push available- when you push any button-it's all or nothing. And on the bottom, there is a sliding lever "L" shaped-you push with your thumb that has a tiny housing over 3/4's of it. (The bottom of the L protrudes and the rest of the L pushes into the housing. It doesn't move at all, unless the right numbers have been entered. Mine seem like they might be a little harder to break into to? (But with your talents, I'm sure they'd be no match. :) Thanks again, I thought I was going to have to throw one out.

[@LockNoob]

I always suspected how these worked, but wasn’t sure, so thanks for showing us. Will have to get one to play with at some point :-)

[@Potti314]

Happy that I could help satisfying your curiosity - they are really fun to play with for a limited time. Problem is that you cannot easily change the combination. So you have to be very forgetful to have the same fun again and again ;-)

[@TallanPick]

Very cool, I have a couple of this kind vintage padlocks, is great to see their guts, thank you for showing and, as always, great decoding my friend ;o)))

[@Potti314]

Thanks buddy, it's always fun to look inside :-)

[@Leonslockpad]

Awesome video my friend I have one of these very cool to see what's inside it👍😊👍😊😎😎

[@Potti314]

Thanks buddy - I was also quite curious :-)

[@JasonCarlson]

Neat lock! Thanks for dissecting..

[@Potti314]

Cheers :-)

[@cherokee8647]

Cool lock and opening Potti.

[@Potti314]

Thank you.

[@crankylock7844]

Good expo.You have set me in the right direction to give the one i have a opening attempt. The one i have is an Abus so the tolerances might be a bit more precise.I am sure the internal design would be similar. Cheers:-)

[@Potti314]

Good luck with lock my friend and have fun - the better the tolerances, the more interesting it gets ;-)

[@carlociruelos862]

Thank you sir for this video it helps me a lot👏👏👏

[@Potti314]

Glad it helped.

[@lockmania-locks]

Cool, also tried this type, they are fun to Play with.😃

[@Potti314]

Haha - yes quite a nice toy ;-)

[@Jacrys.I]

dangg best tutorial ever now i unlock my lock lol i can use it again

[@bogucha12]

Yeah!!! It works!!!I did it!!! Thanks a lot!!!

[@Potti314]

Cheers - thanks for he feedback :-)

[@DonzLockz]

Great explanation and demo. I have one with a lost code, I must try it out now. 🔐🍺😎

[@Potti314]

Lucky you to not know the code - doubles the fun :-)

[@two_tier_gary_rumain]

It's not that hard to work out. Each button only has 2 states and, with 8 buttons on this lock, that would be 8 squared or 64. With 4 required, that's 64 / 4 or 16 possibilities.

[@Potti314]

It's more the fun of feeling when you decode the lock, not the pure opening. And on locks where the combination cannot be changed it's an advantage to not know the code so that your feeling wouldn't t get distracted. As far as the number of possible code concern, these are 2 to the power of 8 = 256. It's like a byte. With every button the number of codes doubles => 2*2*2*2*2*2*2*2 = 256. The question how many possible combinations exist if 4 buttons have to be up is 70. This calculates from the binominal coefficient - 4 out of 8. Check out this page for example www.ohrt.com/odds/binomial.php

[@two_tier_gary_rumain]

@@Potti314 OK, I was going to guess 4! next. :)

[@Potti314]

I think we both have learned not to guess ;-) Cheers buddy :-)

[@johnmccormick2883]

Very nicely done as usual 👍🏻 While you were taking it apart I was thinking to myself ... I hope he takes the buttons out ... then ... I hope he changes the combination... Great Stuff! My only question is what holds the lock together? I assume it’s just pressed fit ??? No pins or screws???

[@two_tier_gary_rumain]

Seems to have three pins in the back. He appears to have drilled them out.

[@Potti314]

Thank you and sorry for not showing how it came apart. Yes, there a three rivets that I had to drill out.

[@chloephilippe4893]

@@Potti314 Is it easy to do? Do you think a locksmith can do that?

[@chloephilippe4893]

And then close it back securely again?

[@BruceNzvi]

How do you change the pin

[@curthatt6461]

Very cool!

[@Potti314]

Thank you :-)

[@dolfooorbe8150]

Is it possible to change the combination of the lock?

[@Potti314]

No, this lock is not capable of altering the code.

[@jojotan2261]

I have a similar one at home, how do i reset the password. Mine is 35780(default pin) but i want it to be 12345 how do i do it

[@pbanikk]

Thanks it helped! ♥️

[@Potti314]

Glad to hear.

[@TinkersTales]

I wold have liked to see you actually hack the lock open.

[@Potti314]

I decoded it - doesn't this count as hacking? Here's another video about these kind of locks kzbin.info/www/bejne/r3KnlKSPbsuBjrs Maybe you like it better.

[@WilliamMancel]

Interesting lock my friend. You think like myself. If I have two locks of the same type, and I'm curious as to what is inside, it's coming apart. 😁You can learn so much from disassembled locks, and examining the mechanism.

[@Potti314]

Yeah, it always nice to have a second item of the same kind to perform experiments with ;-)

[@cavemansparkey4949]

cool lock thanks for shearing i have 1 suggestion please do less hand moving when you are explaining how they work it was hard to see what you were talking about because you moved you hands a lot thank you

[@Potti314]

Alright, got it and thanks for letting me know. It comes to my list of things to consider before starting the video recording - correct lightning, try not to say "ääää" and don't zoom in too much and move the parts - will work on it.

[@kristiendebeuckelaere3563]

How do you open it? I’ld like to change the code.

[@Potti314]

You can only pry it open and thereby compromise the security as it will not stay closed securely anymore.

5678 is a terrible code to be stuck with.
