Chevrolet Car Key Replacement: What Type of Key Does Your Chevy Use?
Not every Chevrolet key is created equal, and the right replacement approach depends entirely on what your vehicle uses. Older Chevy models from the late 1990s through mid-2000s often relied on VATS (Vehicle Anti-Theft System) keys with a small resistor pellet embedded in the blade — a detail many generic locksmiths miss, but that our technicians account for every time. Mid-generation models moved to transponder-chipped keys where the blade cut alone is useless without a correctly coded chip frequency matched to your immobilizer. More recent Chevrolets, including the Blazer and the all-electric Blazer EV, use proximity smart keys and push-button start systems that communicate with the vehicle through rolling encrypted signals.
Identifying your key type before calling saves time. Check your owner's manual, or simply tell our dispatcher your model year and trim — we will identify the correct key profile and arrive with the right blank and programming software loaded. We make Chevrolet keys on-site, cutting and programming in a single visit, which eliminates the dealership's two-step process of ordering a blank, waiting days for delivery, and then scheduling a separate programming appointment.
