trap-pins myth or reality ?

Would turning the cylinder very quickly defeat this.

Only if you knew that lock brand or model line used those pins. Otherwise it would be a very unpleasant surprise. I suppose just as you pick it open, remove picks and insert a plug spinner and it could possibly work.

good question man.

You would imagine so, however, the springs above the trap pins are usually quite strong and the trap pins themselves quite skinny so even a plug spinner purportedly wont work (according to the literature anyway, I've never tried).

Would this work

[Jaakko]

It would be interesting to design a 2 piece trap pin which if activated would telescope out by the springs pressure, and the 2 pieces lock into place when the two pieces are fully extended.

Think of a small tube contains a spring and under that two pins. The point where the pins meet, there the pins would have 45 or 60 degree cut, so that when the lower pin fires out of the tube, the beveled end of the upper pin pushes it a little aside so that it can't be reset.

This is my understanding as well, because the springs used for the trap pins are given crazy pressure so that the trap pin will catch before anything else. I seem to recall a TOOOL presentation about bumping of locks with trap pins where they attempted many various techniques to spin the plug past the trap pins but were unsuccessful each time.

dlink, that method is a bit far-fetched. You're going to end up freezing the lock, which is not what you want to do.
TOOOL did test the M&C Antiklop (one of the first locks with trap pins) with various methods including packing the keyway with dental floss, and using a plug spinner. As I recall, not one of their methods worked, and the trap pins deployed as a result.
