Security System & Immobilizer
GMC follows GM’s security ladder — VATS, PassLock, PK3/PK3+, ID46 Circle+ keys, and modern proximity fobs.
On the 2500 / 3500 specifically we see: Hitag2 Extended / ID46E (PCF7937E). A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.
