What Type of Chevrolet Key Do You Actually Have?
Chevrolet has used at least five distinct key technologies across its lineup over the past three decades, and knowing which one your vehicle uses changes everything about the replacement process. Older models from the mid-1990s used basic mechanical keys with no electronic component — a locksmith simply cuts a new blade to match your door and ignition. From the late 1990s onward, most Chevrolets moved to transponder keys: the key blade carries a microchip that exchanges a coded signal with the vehicle's immobilizer. If that chip is absent or unprogrammed, the engine will crank but refuse to start. Remote-head keys combined the transponder chip with lock and unlock buttons in a single unit, while key fobs (separate remotes) work alongside a traditional ignition key. The newest Chevrolet models — including the Blazer EV — use proximity smart keys or push-button start systems that authenticate wirelessly without ever entering a lock cylinder.
Understanding this terminology matters for one reason: the work required to replace each type differs substantially. A transponder key demands programming equipment connected to your vehicle's OBD port, not just a key-cutting machine. A smart key requires pairing to the vehicle's body control module. Our mobile technicians are experienced with the full range of Chevrolet key generations, so they arrive with the right equipment for your specific year and trim — not a one-size-fits-all kit.
