To start off with, here is a new one!! Currently I can't pick it.
The second pin in the lock comes in from the top left and blocks off a lot of the bottom half of the keyway.
With the key partially in the lock we can see the side pin being pushed far enough to extend past the housing.
I filed down the bottom tips of the driver pins in the last four chamber so that they can't be set at the shear line before the first two pins in the lock are set. The first pin is a 9 depth, and with a large portion of the keyway blocked by the second pin...
Ok, on to the links of other locks I've modified.
Basic threaded chambers and tapped pins.
Jruther2 got a hold of this lock with threaded chambers and anti-bump pins and did a great write up here. http://keypicking.com/viewtopic.php?p=26330#p26330
This next one is a 12 pin lock that uses a wave like key.
Clutching lock cylinder.
Nightmare Yale. I never did pick this one. However, Toolymcgee did. Simply Incredible.
The lock that was never intended to be opened with a key.
Multiple shear lines.
Custom dimple lock with sidebar!
Corbin Master Ring modifications. (Probably the most pick/impression resistant lock I will ever come up with)
Medeco pins replaced with screws. I never did take pictures of this lock, but I did get it on camera!
