It's a complete, fully functional smart key fob (not just a shell) that matches part number M3N32337100 and operates on 315MHz frequency. It has three buttons: Lock, Unlock, and Panic alarm. It comes with a battery installed and is made to fit 2015-2021 GMC Canyon and Chevrolet Colorado models (also compatible with some Silverado and Sierra years – check the full list). Important: This is a non-OEM (aftermarket) part, and it MUST be programmed to your specific vehicle by a qualified locksmith or dealership.
