Chevrolet Car Key Replacement: What Type of Key Does Your Chevy Use?
Chevrolet has used several key technologies across its model lineup over the past three decades, and knowing which type your vehicle uses is the first step toward a fast resolution. Older models — think early 2000s Impalas and Silverados — use a basic laser-cut or double-sided metal key with no chip whatsoever. Mid-era models introduced transponder keys, which contain a small RFID chip in the head of the key that must be programmed to match your vehicle's immobilizer system. If the chip signal is absent or mismatched, the engine will crank but will not start, which is a security feature that also means a cut-only key from a hardware store will leave you frustrated. More recent Chevrolets — including the Blazer EV and newer Equinox models — use remote key fobs or push-button smart key proximity fobs that communicate with your car continuously. Each of these key types requires different tooling, different software, and a different level of technical expertise to produce correctly.
Our technicians arrive at your location with professional-grade key-cutting machines and OBD-II compatible programming tools that cover the full range of current and legacy Chevrolet platforms. We do not rely on a one-size-fits-all approach: we look up your specific year, make, trim, and VIN to confirm the exact key profile and programming protocol before we begin. This matters especially for vehicles like the Blazer EV, where the push-to-start system requires a paired smart key rather than a traditional blade. If you're in a Chevrolet Blazer EV car lockout service situation near Selbyville, our team can reach you quickly and handle the programming on the spot rather than leaving you waiting days for a dealer appointment.
