Unpickable Locks

[pick_this]

While I was thinking of how a lock works I thought of this "unpickable lock". OK , check it out its like the pins have threads like a screw, and the hole they slide up into is threaded to. The key that you use in the lock have like little curves cut into the little deals the push up the pins that unscrew the pins when you put the key in and to screw them back in when you pull it out. But the threads are only on the bottom of th hole so after the pins are unscrewed they could be pushed up into the hole. Even if only one pin screwed into place, it would prevent you from pushing the pin up to the sheer line, so you can only set the pins that aren't screwed into place. I'm sure that one of you could come up with a way to pick it. Eh?

Hmm.... another unpickable lock thread

But anyway- if I read your plan correctly, gravity has no effect on the pins, no? Well, lets say you have 5 pins and the cuts are 5,3,4,2,1. When you insert the key, the first position that enters the keyway (position 5, depth 1) will "unscrew" the pin very high, but when you finish putting the key in nothing will be able to force it back down to fit the first position (depth 5).

And plus- there is no such thing as a 100% unpickable mechanicle lock. You can always manipulate it to simulate the key.

Ahhhhhh! I see. So what your saying is that the tip of the key would screw up the action of the first pin and so on.

And also I know that you said that no mechanical lock is 100% unpickable but what about those "Laser Locks" made by Masterlock? Do they work on about the same principle that keyless entry locks do for cars and trucks?
I'm sure that someone has come up with an electronic device for opening these locks without the supplied keys, right?

Mechanical = No electricity involved

[pick_this]

Yeah, what I was saying was that I understand you said mechanical but I was just wondering about the electrical locks. Maybe I should have been more clear in my post

There is probobly some kind of multi-million $$ safe or something out there that is impossible to get into w/o drilling it or something. But I dunno...

Probably something like this:

Well, combination locks (in theory) can always be brute forced.

I imagine that because picking a pin tumbler lock for example requires reading feedback, that is to say using your senses to manipulate the lock, in theory all one would have to do is create a lock that is machined so that the mechanics are beyond the threshold of human senses. But then you could probably create some other kind of tool that is more sensative.

It all comes down to cost effectiveness i guess, as it always does. Round and round we go.

[mcm757207]

Because humans created machines, no machine is 100% perfect. Of course there are some that come really close, but it's because of these small imperfections that we are able to manipulate tumblers and such to pick the lock.

So does anyone know what type of lock is currently the hardest to pick to the point where it is almost impossible?
