Chevrolet Car Key Replacement: What Makes Chevy Keys Different
General Motors began embedding transponder chips in Chevrolet ignition keys in the mid-1990s, and the technology has advanced steadily ever since. Today's Chevy lineup spans everything from basic single-chip keys found on older Tahoes and Impalas to rolling-code smart fobs and proximity keys used on the Blazer, Blazer EV, Traverse, and Colorado. Each generation requires a different programming protocol, and some models — particularly the Blazer EV — use an entirely phone-based or card-based access system that demands specialized equipment most roadside services simply do not carry. Our technicians arrive with professional-grade key programmers, a broad inventory of key blanks and fob shells, and the vehicle-specific software needed to complete the job correctly the first time.
When a Chevrolet key is lost entirely, the process involves three steps: cutting a new key blade to the door and ignition profile, programming the transponder or smart key to the vehicle's BCM (Body Control Module), and — on many late-model trucks and SUVs — erasing the lost key from the system so it can no longer start the vehicle. Skipping that last step is a common oversight that leaves owners vulnerable. We walk through all three steps on-site, right there in your driveway, parking garage, or on the side of Lamar Avenue if that is where you need us.
