Chevrolet Car Key Replacement: What Type of Key Does Your Chevy Use?
The first step in any Chevrolet car key replacement is identifying exactly what system your vehicle uses, because the process and parts differ significantly by model and year. Pre-2000 Chevrolets typically use basic cut metal keys with no electronics — these are the quickest to duplicate. Models from the early 2000s onward introduced transponder keys, where a small chip embedded in the key head must be programmed to match your vehicle's immobilizer or the engine will not start even with a correctly cut blade. By the mid-2000s, Chevrolet began rolling out remote head keys — a fob and key blade combined in one unit — and later moved toward proximity smart keys for vehicles like the newer Blazer, Traverse, and Equinox, where you keep the fob in your pocket and press a button to start. The Chevrolet Blazer EV, now appearing more frequently on Queens streets, uses a fully proximity-based smart key system that requires specialized OBD programming equipment to pair a new fob to the vehicle's onboard computer.
Our technicians identify your key type from your VIN and vehicle information, source the correct blank, cut it to your door and ignition on our mobile key machine, and complete the programming on-site. We verify proof of ownership — registration, title, or ID matching the vehicle — before any work begins. This step protects you as much as it protects us, and it is a practice we never skip.
