| This is the special tryout set for GM 6 cut locks (1967 and up). It's cut on a special nickel silver key from Jet, B15, that will bypass all the different keyways including door, ignition and VATs ignitions as well. 211 keys.
Please note that GM has redesigned the wafers in the locks in 1995 or so. Therefore for newer locks, we recommend at least 3 years of good wear on the locks to use this set on those locks. Otherwise, your poor fingers are going to get tired!
