Chevrolet Car Key Replacement: What Type of Key Does Your Vehicle Use?
Chevrolet has used several different key technologies across its model years, and knowing which one your vehicle requires is the first step toward a fast resolution. Older Chevy trucks and sedans from the late 1990s and early 2000s typically use a basic cut metal key with no electronics — these can usually be duplicated or originated quickly on our mobile cutting equipment. Mid-generation Chevrolet vehicles introduced transponder chip keys, where a tiny microchip embedded in the key head must be programmed to communicate with the vehicle's immobilizer. Without that programming step, a perfectly cut key will turn in the ignition but the engine will not start.
Newer Chevrolet models — including the Blazer, Blazer EV, and higher trims of the Traverse and Tahoe — use proximity smart keys or remote head keys that combine keyless entry, remote start capability, and push-button ignition into a single unit. These require both precision cutting and advanced on-board diagnostic programming. Our technicians carry the professional-grade programming tools to handle all three categories on-site in Montpelier and throughout the surrounding Williams County region, often completing the work faster than scheduling a dealer appointment and transporting the vehicle.
