GMC Key Types We Can Help With
GMC key systems vary by vehicle year and model. Older GMC trucks, roughly through 2006, mostly used metal keys; chip keys became common around 2007, with flip and smart keys appearing on later vehicles. We confirm the exact year and model with you before determining which key service fits.
Traditional metal keys
A metal key has a cut blade that turns the vehicle’s lock and ignition. Many older GMC trucks used this style, though the key type can vary by year and model.
Transponder chip keys
A transponder key includes a chip that communicates with the vehicle’s security system. Cutting the blade alone may not be enough; the key may also need programming at the car.
Remote-head and flip keys
These keys combine a mechanical blade with remote buttons, either in a fixed head or a folding design. Depending on the GMC’s system, the key may also use a transponder.
Smart keys and key fobs
Some later GMC vehicles use a proximity key or fob rather than a conventional key that must be inserted to start the car. A GMC key fob replacement may involve preparing and programming a fob for the specific vehicle.
