(picking 759) Why this combination lock is so hard to decode (manufacturer tricks revealed) 

I received this lock from a viewer to decode it. It was a 30min job as the lock manufacturer has has built in properties to make decoding very difficult: pulling not straight by design, tight tolerances, two types of false gates to prevent continues decoding and pretend a wrong number to be correct. This video is not an actual decoding session but explains the lock secrets and gives general decoding advices.

Thanks for showing the inside. Those undercuts were particularly interesting.

This was the best video that accurately describes what was going on with The lock I found. It does make your fingers hurt. I solved it also in 30 min. With the luck method. Lol

Thanks for the video! I have the same lock and none of the other tutorials worked. This lock definitely has advanced measures to prevent cracking it. Actually seeing how the inside works will help tremendously! I'm determined to open and be able to use it again!

Fantastic explanation Potti, it's great to see a decent combi lock. Take care and have a great week.

Hi Potti314, Interesting combination lock mechanism, 5 numbers, variable system for false gates. Certainly the manufacturer has gone the extra mile to deter a pull pick attack. Thoroughly and well explained by yourself, as usual. I found it very interesting. Regards, Brian.

Ich übe erst seit ein paar Tagen. Bin irgendwie fasziniert wie schwer manche Schlösser zu öffnen sind. Deine Arbeit ist der Wahnsinn !

A combination lock which puts up a fight is rare. Thanks for the video. 🙂👍

Thank you for the lesson, stay well

Thanks heaps Potti ! Mine had 4 wheels but 2 types of false gates... Using the Indirect method I wrote down 3 possibilities from the tightest wheel on the left and proceeded from there , eliminating some of the "good" numbers as I went. I Noticed that the "good" numbers caused the next wheel to not make clicking noises when turned. Prost!

Very innovating, but then again, people find hard to remember 3 digits combination, not to mention five. Great job my friend!

nice job. Keep up.

Interior lighting views are fantastic! I hope this visualization can be used with many more locks. Thank you! I also wonder if "hanging" the lock under weight tension with some sort of distance micrometer for the different settings might be useful. For example, you mention that with some combinations the separation is greater/lesser than others. I would be interesting to see if the micrometer separation might useful for minimizing the number of trials necessary.

Thanks for the video, most informative. I have a brand new 5 digit combination lock that I messed up when setting the new code. I've tried for weeks to crack it using your method but so far all I have are aching wrists and sore fingers. I tried WD40 to help in twisting the wheels, is that something that is useful in your experience? I know it has false gates as I could see them when trying to replace the central bolt.... Also is it harder to pick a new bike lock or an old well used one?

Always nice if effort is put in by manufacturers to keep locksport interesting 👍It would have been a practical lock if the physical strength was at a decent level. Clear video 👍

I got one like it. I don’t recommend anyone buying one of these locks for valuables. Fun to practice decoding with.

Can you pick a combination lock that is already open? I forgot the number combo to my bike lock, but the lock is already open so I cannot put tension on both sides of the lock

Thanks for show this and some nice hint's on helping to open it. Do you know who makes the lock?

Interesting lock - thank you for showing this! :D ... for the indirect method, the 1 and the 6 were binding, as one of them was a false gate ... is it always half way around for each wheel? ... and only 2 of numbers do that for the indirect method? I'm thinking that would reduce the possibilities to just 32 combinations. Cheers!

I have one with 4 numbers and it’s not working with any methods I’ve looked up. It’s so annoying because I don’t want to buy a new one and it was my dads old one. I looked up the name of the lock and can’t find specific decodes.

Does kryptonite has false gates?

Just curious. The undercuts feels like they would be wider than the gate/false gate. Would this perhaps enable you to feel what numbers are undercuts, and then know that these numbers cannot have gates. That would cut down the amount of numbers to try to half. That might also enable you to put all the wheels to "known undercuts", giving you a few extra micrometers to feel for gates.

Hey @potti314 I have a serenelife 4 digit combination box, that i cant decode, nor break into. What should I do.?

Great video, Sometimes you have to "BE the Lock", ;)

are u in new york

What is the brand? Seems like a hard to de-code lock. And ANY lock can be forced/cut , given time.

How its made

just use a Peterson tool job done
