Chevrolet Car Key Replacement — What Makes Chevy Keys Different
Chevrolet has used several generations of key technology across its lineup, and the type of key your vehicle requires has a direct impact on how it is replaced. Older Chevy trucks and sedans used a simple mechanically cut key with no electronics whatsoever. Starting in the mid-1990s, Chevrolet introduced transponder chips embedded inside the key head — the vehicle's immobilizer must recognize the chip's signal or the engine will not start, even if the cuts are perfect. Later models moved to remote head keys that combine the cut key and a fob into one unit, and the most current Chevrolet vehicles — including the Blazer EV — use proximity smart keys that allow push-button ignition without inserting anything into the ignition at all.
Each of these formats requires a different process to replace correctly. A transponder key that is cut but not programmed will open the door and do nothing else. A smart key that is not paired to your specific vehicle will be equally useless. Our technicians are experienced with all of these Chevy systems and carry the programming hardware to handle them on-site, whether you are stranded on South Walnut Street or parked at the Milford Farmers Market on a Saturday morning.
