Overly Elaborate Anti-Picking Suggestion

[fgarci03]

Ha! Great!



Never thought about that!

[ARF-GEF]

I don't think it's feasible.

You would have to fill it, close it watertight, and pick it at the same time? I don't think you could pick and close it and manipulate the lock with a pick at the same time. At least it would be greatly difficult.

Even if you could:
Cylinders are not watertight, they would leak out in the back. (or in the middle in case of Euro cylinders) Also the resistance of salty water would be very different from a brass or a steel key.
Alone closing the back of the lock watertight would be veery hard to do.

[Quickpicknpay]

Yes, but if you have ever lubricated a lock (I'm sure you have) you would see that the lube gets into every little nook and cranny working its way up beside the bottom and top pins and staying there for some time. I Think the liquid would still make contact and complete the circuit for a while withought having to keep it "full" of liquid.

[ARF-GEF]

Possibly yes
I'm not sure. I guess we would have to try it to see it.
But if you think about my idea (electric contact on both the top and the bottom of the keyway) that would make this liquid solution much harder.

But I've been wondering about it and I think that a longer used lock may have connection problems in itself due to wear (abrasion).

All right scheemers, design this.

Suppose you have a lock where you insert the key, turn it 15 degrees, and insert it deeper. The second set of pins cannot be reached in a straight line because of the 2 - 90 degree turns that the bent key blank has to navigate.

[Quickpicknpay]

I am not sure if I understand this fully but if you can insert the key lets say halfway and then turn to then fully insert the key and turn again to open the lock, couldnt you just pick the first half to the right angle and then pick the next half? You say it has a bent key. How does it get inserted fully with a bend in it? I think I need a little more info to better understand how it works.

[Raymond]

I am trying to imagine a key with two bends in the bow before the cuts start. The cuts go completely into the lock to set the pins. Something on the base, tip or shoulder prevents the key from going deeper until the plug is turned. In turning, the plug is covered by a blocking plate and the key goes in another cut deeper. The face of the lock would prevent direct access to the pins after the plug is turned. You could pick the first turn but after the keyway is blocked to a straight view you can no longer access the pins. This is similar to the curtain and a ward on a lever lock but would have a separate set of levers after turning and pushing. Haven't built it, just brainstorming.

[Quickpicknpay]

I'm guessing this would require two sets of top pins and springs for the key to move in to reach the final bottom pin otherwise it would not be able to move as you wouldn't be able to lift the first set of pins allready at the shear line. Unless the plug was split before the final pin and there was a spring between the first and final section of the plug allowing it to engage the back section of the plug when pushed in and then lift the final pin to turn further. But this could still be manipulated.
I may have missed something as I'm immagining a few different variations of this in my head, keeping in mind how each variation can be defeated.
I like the idea of a front curtain though. Food for thought.
Brainstorming is good, more of this creates a snowball effect and many ideas branch off into hopefully what will turn out to be a pretty good lock as an end result.

If a key that's pushed in further should still turn, the "front pins" would need some type of master keying, or the shear line would have to be disabled in some other way (maybe a mobile part) at the second position.
But a nice idea indeed. Think "Lafette".

You mentioned that it is a victim of key duplication as is many locks. If you think about it medeco are able to be beat with a credit card.

I would like to see a tutorial on this.

It is possible, though likely not what you're thinking. Probably isn't appropriate for discussion outside of Advanced, however.

Buy Open in Thirty Seconds, or you can find the info on the web.

I would think that keeping parts and gizmos to a minimum would be more reliable and less likely to bypass.
You could end up with a lock with as many segments as a centipede.
My father in law who was an engineer always told me "the fancier you make the plumbing,the easier it is to clog the drain".

This may give you some ideas. You could either use the force from inserting the key to charge your battery, if you still want to go that route. Or possibly engineer something (I think) would be new.
Instead of using two pins to create a sheer line, use a single pin in each stack, sense the force applied and if all equal true, release a side bar.

Good luck!
