GMC keys — what you should know
GMC shares GM key architecture with Chevrolet, so coverage and procedures are the same across the equivalent models. Sierra and Yukon proximity keys are supplied and programmed on site. Work vans and service bodies often have separate cargo and compartment locks that can be keyed to the ignition key, which is worth doing on a fleet.

GMC keys — questions
Can you make a GMC key if I have lost all of them?
For most GMC models and years, yes, and at the vehicle rather than at a dealership. B111/B119, shared with Chevrolet — we cut from code obtained through authorised channels or by decoding the lock directly, then program to the immobiliser on site. GM immobiliser architecture, identical procedures to the equivalent Chevrolet. We verify ownership before any of it, every time.
What kind of key does a GMC use?
B111/B119, shared with Chevrolet. GM immobiliser architecture, identical procedures to the equivalent Chevrolet. This matters because cutting alone is never enough on a modern vehicle — a key cut without programming works the lock and turns the ignition, and the engine cranks and does not start. Give us the year and model and we will tell you exactly which key your car takes before coming out.
How much is a GMC key, and how long does it take?
Price follows the key type, not the badge — a transponder key is at the low end, a remote head key in the middle, a proximity smart key at the top because the blank itself is expensive. A spare with a working key present is usually thirty to sixty minutes on site. All-keys-lost takes longer, and several makes impose a manufacturer security wait of ten to sixty minutes during programming that nothing can shorten.
