Types of Chevrolet Keys We Replace and Program On-Site
Chevrolet has used several distinct key systems over the past three decades, and knowing which one your vehicle uses determines the tools, parts, and time required for a proper replacement. Older models from the late 1990s and early 2000s typically used a basic laser-cut or double-sided mechanical key, sometimes paired with a separate remote fob for door locks. Models from the mid-2000s onward introduced transponder keys — these contain a small microchip inside the head that must be electronically programmed to match your vehicle's immobilizer before the engine will start. Without correct programming, a perfectly cut key blank will crank the engine but never fire it.
More recent Chevrolet models, including the Blazer EV and other current-generation vehicles, use proximity smart keys that allow push-button starting as long as the fob is within range. These require both precise cutting and two-way programming between the fob and the vehicle's Body Control Module. Our technicians arrive with OBD-level programming devices capable of handling GM's current software protocols, so we can produce a fully functioning key on the spot. If you drive a Chevrolet Blazer EV and find yourself dealing with a Chevrolet Blazer EV car lockout service situation or a failed key fob, our mobile unit is equipped specifically for that platform — no dealer trip required.
