Chevrolet Car Key Replacement: What Type of Key Does Your Vehicle Use?
Not every Chevrolet key is the same, and understanding which type your vehicle uses directly affects how the replacement is handled. Older Chevy models from the early 2000s and before may use a basic cut metal key or a VATS (Vehicle Anti-Theft System) key that carries a small resistor pellet embedded in the blade. Mid-era models introduced transponder chip keys — the key blade cuts the ignition mechanically, while the embedded chip communicates with the vehicle's ECU to authorize the start. Without a properly programmed chip, the engine immobilizer stays active even if the key turns freely.
More recent Chevrolet vehicles, including many Equinox and Traverse trims, use remote head keys or key fobs with integrated transponders that handle both locking and ignition functions. The Blazer EV and other newer Chevy platforms use proximity-based smart keys, meaning the vehicle detects your key in your pocket and allows push-button starting. Each technology requires specific cutting equipment and programming tools. Our technicians arrive with the hardware to identify your exact key type, cut a new key to your vehicle's specifications, and complete all necessary programming on-site — without towing your car anywhere.
