Chevrolet Car Key Replacement: What Type of Key Does Your Chevy Use?
Chevrolet has evolved its key technology significantly over the decades. Older Chevy models from the 1990s and early 2000s typically use standard or double-sided metal keys that can be cut from a code or by duplicating an existing key. Starting in the mid-2000s, most Chevrolet vehicles began using transponder keys — keys with a small microchip embedded in the head that must be electronically paired to the vehicle's immobilizer system. If the chip isn't programmed correctly, the car's engine will crank but refuse to start, even with a perfectly cut blade. This is one of the most common calls we receive from Chevy owners across the five boroughs.
Newer Chevrolet models — including the Equinox, Tahoe, Suburban, Silverado, Malibu, Traverse, and Blazer — use remote head keys or proximity smart keys that combine the mechanical key, remote lock/unlock functions, and sometimes push-button start capability all in one unit. The Chevrolet Blazer EV, for example, uses a fully electronic proximity fob that communicates with the vehicle's passive entry system. Programming these requires dealer-grade diagnostic equipment, which our mobile units carry directly to you. No tow truck, no dealership appointment, and in many cases no wait beyond our response time.
