Chevrolet Car Key Replacement: Every Model, Every Key Type Covered
Chevrolet has used at least five distinct key technologies over the past three decades, and the replacement process for each one is genuinely different. Pre-1995 models use a straightforward mechanical blade that can be duplicated by cutting a new key to code — no electronics involved. From the mid-1990s onward, Chevrolet introduced transponder chips embedded inside the key head. If the chip is missing or unprogrammed, the engine immobilizer trips and the vehicle will crank but not start. Our technicians carry the diagnostic and programming hardware to read your vehicle's immobilizer and write a new key to it on the spot.
Remote-head keys — the kind where the fob buttons are built into the key itself — are the standard on models like the Silverado 1500, Tahoe, Suburban, and earlier Equinox generations. Fully separate key fobs that communicate with a push-button start system are common on newer Malibus and Traverses. The Blazer EV, Chevrolet's all-electric SUV, uses a proximity smart key with encrypted rolling codes that must be programmed with dealer-level equipment — which our mobile units carry. Regardless of which system your Chevrolet uses, we can make a replacement key on-site, often the same day you call, without requiring a tow.
