Trap pins?

[GWiens2001]

In my limited experience, trap pins use stronger pins than normal driver pins, specifically to counter plug spinners.

Plug spinner may, or may not, work.

Another difficulty is that some trap pins doesn't fire perpendicular into the plug, but from an angle. This makes some of them virtually unpickable. Others fires into a non-accessible part of the plug, or locks solid as soon as they fire.

Couldnt you pick it to just turn and then use a plug spinner to get it past the dead pins? That sure is an interesting lock...

The springs from trap pins are much more powerfull than for the regular pins, a plugspinner wouln't work, you need to pack it with dental floss.

I am referring to a trap pin where the bottom pin is covered by a thin wafer, like a #1 master wafer. The correct key always raises the wafer above the shear line. If the lock is picked with the wafer down in the plug, as it most likely will be, then there will be nothng to contact the spring loaded trap pin above. If a trap pin has been exposed by picking, the trap is already set. Dental floss would have no effect. A strong plug spinner might still get lucky.
