Re Key Locks

[79vette]

I want to re-key my 88 R30 and my 79 Corvette to use the same key used in my 86 K5. My keyring is getting too fat, and I dont want to split it up because I know I'll lose them all if I do.

The K5 has an aftermarket lock set that use the GM "A" key for all doors, tailgate and ignition.

The Corvette has the original locks, with an A keyed ignition and B keyed doors

The R30 has "D" keyed doors, and I cannot read a mark on the igniton key but its definitely different from the A key in the other vehicles.


Does anyone know if the letter on the key matches geometry cast into the inside of the lock cylinder? IE for the R30 and Corvette, do I need to get new lock cylinders to accept the A key? I suspect thats the case, but dont want to just buy parts I dont need.

Also, does anyone have a source for the wafers, springs and bezel parts for these locks? Or do I need to pull locks at the junkyard to strip for parts or go to a locksmith?
