Chevrolet Car Key Replacement: What Type of Key Does Your Vehicle Use?
Not every Chevrolet uses the same type of key, and the right replacement process depends entirely on your specific model, trim, and year. Older models such as early-2000s Cavaliers and Cobalts typically use a basic cut metal key with a built-in transponder chip — the chip must be programmed to the vehicle's ECU, otherwise the engine will crank but refuse to start. Mid-range models including many Malibu, Cruze, Equinox, and Colorado trims use remote head keys, where the key blade and the lock/unlock fob buttons are housed in one unit — both cutting and remote programming are required. Newer Chevrolet models, including the Traverse, Tahoe, Silverado, and the Blazer EV, increasingly use proximity smart keys that communicate with the vehicle passively, allowing push-button start without inserting anything into an ignition.
Our technicians arrive with the equipment to identify exactly which key system your Chevrolet uses, source the correct key blank, cut it to your vehicle's lock profile, and complete the full transponder or smart-key programming cycle on-site. If you own a Chevrolet Blazer EV and find yourself locked out or without a working key anywhere in the Greater Toronto Area, our Chevrolet Blazer EV emergency locksmith response covers you around the clock — no appointment needed, no tow truck required.
