These picks are called "Rocker" picks because of their special shape and method of use. Their unique shape allows them to be rocked up and down inside the lock cylinder keyway. There are 12 double-ended, single sided GM rocker picks in this lock pick set. This gives you 24 combinations covering the one thousand plus possible key cut configuration for General Motors side bar locks. Each GM rocker lock pick will save you time by replacing hundreds of "try out" keys. Before attempting to use these picks carefully read the instructions enclosed with the set regarding the GM PassKey system and 8 & 10-cut ignition locks.

This set works on most G.M. (Buick, Cadillac, Chevrolet, Oldsmobile, Pontiac, and GMC trucks and vans) steering column, door, and trunk locks. G.M. side bar locks are the most difficult U.S. automotive locks to pick, but with this set and practice, patience, and more practice, you can learn to master these locks. Not for use on VAT (PASS) system ignition locks (the G.M. keys with the built-in microchip).
