Mobile key cutting and programming for GMC vehicles at your location. GMC shares much of its key-system history with Chevrolet, given the shared truck and SUV platforms — mechanical and remote-head keys first, with Smart Key availability arriving mainly on later, higher trims. We confirm the exact key system from your VIN before dispatch.
Each section covers one GMC key system: what the key looks like, and what programming or All Keys Lost service involves. Years are approximate and vary by model, trim and build date. We confirm the exact system from your VIN.
A metal key turns the ignition by hand with no electronic check. A separate remote on the ring may lock and unlock the doors but does not start the GMC.
The anti-theft sensor sits in the ignition lock cylinder rather than in the key. GMC trucks and SUVs share much of this history with Chevrolet.
A chip in the key head is read by the immobilizer. Cutting the blade alone won’t start the vehicle.
Blade, chip and remote buttons in one folding key, often with remote-start and liftgate buttons.
Denali and other upper trims got proximity keys first. Newer GMC trucks and SUVs moved to GM’s newer electrical architecture, which has different programming requirements.
Each model page lists that model’s key systems by year and links back to the matching section above.
The key images, vehicle models, and year ranges shown on this page are provided as a general identification guide and may not apply to every vehicle. The manufacturer may use different key systems within the same model year depending on trim level, production date, manufacturing location, ignition type, and factory equipment. Final compatibility must be confirmed using the vehicle’s VIN, ignition type, existing key or fob, and vehicle information before service. The images are representative examples and do not guarantee an exact visual match.
The 17-character vehicle identification number, from the registration, title, or dashboard.
