Beveled plug holes?

[Key]

Hi there,

Picking again. This time on a somewhat more difficult lock from the brand "Kraft". As far as I can deduce it has 5 pins.

Well, I opened it four times (I also failed on it many many times) and tried to rethink what I was doing just before the locked opened. I was scrubbing over pin 3-5.

When I closed the lock (with the tension wrench) I did it very slowly. And I listened. I heard way more than 5 clicks! More like 8-10...
Could this mean that the plug holes are beveled? Could it also mean that there are some security pins which are setting back to a "jammed" situation and finally to the closed situation (less likely I suppose)?

Are there a lot of locks known which have beveled edges AND security pins? I guess so, but just want to ask the experts

Thanks a lot.

Key.

sometimes the torkylever makes a clicking noise when you move it in the lock.

My guess is that you have been picking with a bit too much force and have overset several pins. When you release tension, you are hearing both the top and bottom pins slamming back down.

Just my guess...

Perhaps, as DB suggests, you have over-set most of the pins and what you may be actually hearing (assuming you are releasing tension very gradually) is the lower pins dropping back into the plug, combined with spool upper pins dropping false-set, then as tension is relased further, the spools dropping back to the rest position.

When I closed the lock (with the tension wrench) I did it very slowly. And I listened. Key.

If the lock was already opened wouldn't the key pins already be flush. I don't know how the key pins would fall if the cylinder was completely turned. Some locks are filed down on top due to improper or sloppy re-keying. The Locksmith will file the top of slightly protruding pins and in turn files the top of the cylinder. You may be hearing the pin hit the filed down part, then the second click may be the pin actually entering the hole. Cylinder with filed down tops are slightly easier to pick in my opinion.

Key pins are generally beveled on the edges (how much depends on the lock -- better ones seem to be flatter) to facilitate turning. Doesn't mean much.

Since picking is all about getting top pins to set on the 'step' that is created in the pin channels by torsion, beveling that very step could be a wicked security fix, but it could also make raking easier if all the pins were being worked simualtaneously, or perhaps its no different from beveling the pins, which we know is done, and only serves to make the effective shear line wider. Another possible explanation for extra click would be master pins maybe, I don't know, its to early for my brain to be up.
