Chevrolet Car Key Replacement: What Type of Key Does Your Chevy Use?
Not all Chevrolet keys are created equal, and identifying your key type is the first step toward a fast solution. Older Chevy models — think late-1990s and early-2000s trucks and sedans — often use a basic laser-cut or double-sided mechanical blade with no electronics. Mid-generation models introduced transponder chip keys, where a microchip embedded in the key head must be programmed to the vehicle's immobilizer before the engine will start. More recent Chevrolets, including the Equinox, Malibu, and Traverse, use flip-style remote head keys or proximity smart keys that handle both door unlocking and push-button ignition from your pocket.
The Chevrolet Blazer EV represents the newest wave — a fully electric platform with a proximity fob system that communicates with the vehicle's body control module. Replacing or adding a key for the Blazer EV requires both cutting (if a mechanical emergency blade is involved) and module-level programming, steps our technicians perform on-site using professional-grade diagnostic equipment. Knowing exactly which generation and trim level of Chevrolet you own helps us arrive with the right blank and software profile, cutting down wait time significantly.
