Chevrolet Car Key Replacement: What Type of Key Does Your Vehicle Use?
Not every Chevrolet key is the same, and understanding what you have determines exactly what the replacement process involves. Older Chevrolet models — typically those manufactured before the early 2000s — used a basic metal blade key with no electronic component. These can be duplicated quickly with the right blank and cutting equipment. From the mid-1990s onward, Chevrolet began integrating transponder chips into the key head. The chip communicates with the vehicle's immobilizer system; if the signal is absent or unrecognized, the engine will crank but not start. Replacing a transponder key means both cutting the blade to the correct bitting and programming the chip to your car's ECU — a step that requires professional diagnostic tools.
From around 2010 onward, many Chevrolet models — including the Blazer, Traverse, Tahoe, and Equinox — moved to proximity (smart) keys and push-button ignition systems. These key fobs use encrypted rolling codes and must be paired to the vehicle through a secure programming session. The Blazer EV, Chevrolet's all-electric SUV, uses a modern proximity fob with additional integration into the vehicle's onboard systems, meaning a 24-hour locksmith with up-to-date programming software is essential. Our technicians carry a broad inventory of Chevrolet key blanks and fob shells, and the on-site programming equipment needed to handle every generation — often completing the full replacement in a single visit.
