Lock that opens after turning 360 degrees?

Postby BreezerFly » 5 Sep 2012 11:41

Heya,
I heard somewhere, that it's dangerous to turn the lock 180 degrees, or more, because the driver pins might fall into the keyway if it aligns with them. So, how would I go about opening my main door? It requires a 360 degrees counter clockwise rotation.

And nope, I'm not going to go and pick it, no reason to :) I wouldn't be able to get in it anyways... I'm still having trouble with a 5 regular pin padlock ^^ Or well 'troubl'e, but I'm trying to feel what happens so I can predict when it opens, rather than being surprised when it does :D

When your key is inserted it occupies the space where the driver pins want to fall into, so with a key there you can turn 180,360,720 or however much you want to turn because the key will stop the drivers from falling in. The 180 problem is only for picking a lock with a pick and a wrench.

Good question. It's often said that pictures are worth 1000 words... and there's a thread with a bunch of great photos here that shows you exactly how to fix this problem, if you ever encounter it while picking.

This is usually only really an issue on some master-keyed locks, if the drivers are small enough they can actually fall out into the keyway, rendering the keys useless until it is repinned.

Yeah, I've realized it's not a problem with my key, since I've used it for a few years now :P But the issue was with the picking, because if I locked myself out and needed to get in, using picks. How'd I prevent it from happening... :)

So I need some sort of clipper that matches the broad side of the keyway, and covers it all.Thanks MacGyver101 for illustrating :D

You can use nearly anything, the example shows a tensioner being used, but most picks can be flipped upside down and used as well. really anything that fits down there will work.

I find when picking euros they don't lock up at 180 too often. It's usually only when the lock is pretty well worn, and even at that I've never had a driver pin go into the keyway. You just need to push them down with the back of the pick and turn.

Considering this is a residential lock and not some kind of master system there really is no concern... but if you're really that worried about pins springing into the keyway and killing the lock, before it hits the 180 position all you have to do is put your pick into the keyway and push down a little to keep them out of the road as you turn past it. Or if you prefer to be less expedient, use a filed down key blank to occupy the space.
