Chevrolet Car Key Replacement: What Type of Key Does Your Vehicle Use?
Not every Chevrolet key is the same, and the replacement process varies significantly depending on your model year and trim. Older Chevrolet models from the late 1990s and early 2000s typically use a basic double-sided laser-cut or sidewinder key — a mechanical cut with no electronics inside. Starting in the mid-2000s, Chevrolet began embedding transponder chips into key heads; the chip sends a signal the vehicle's immobilizer must recognize before the engine will start, meaning a key that is cut correctly but not programmed will still leave you stranded. From there, Chevrolet moved to remote head keys that combine a chip with lock, unlock, and panic buttons in one unit. More recent models — including the Chevrolet Blazer EV and other current-generation vehicles — use proximity smart keys or advanced push-to-start fobs that communicate continuously with the car's body control module.
Understanding which system your Chevrolet uses matters because it directly affects what equipment is needed and how long the process takes. Our mobile locksmith technicians carry professional-grade key-cutting machinery and automotive programming tools that support the full range of Chevrolet platforms — from VATS systems on older models to the latest PEPS (passive entry, passive start) configurations on newer ones. We identify your exact key type before quoting or starting, so you know exactly what the job involves.
