Chevrolet Key Types We Replace and Program
Chevrolet has used several key technologies across its lineup over the decades, and knowing which type your vehicle uses matters for a successful replacement. Older Chevy models used a standard metal cut key with no electronics — straightforward to duplicate on-site. From the late 1990s onward, Chevrolet shifted to transponder keys, where a small chip embedded in the key head must be programmed to match the vehicle's immobilizer system; without that programming step, the engine will not start even if the cut is perfect. Later models introduced remote head keys — a combined key and fob — followed by proximity smart keys that allow push-button starting without inserting anything into the ignition. The Chevrolet Blazer EV and other recent Chevrolet models use advanced encrypted key fobs that require dealer-grade programming tools to clone or originate.
Our technicians carry professional-grade equipment that covers all of these formats. Whether you drive a classic Camaro, a workhorse Colorado, or a Blazer EV that you rely on for your daily Huntington Beach commute, we identify the exact key profile and immobilizer protocol, cut and program a replacement key on the spot, and test it fully before we close out the call. We also replace and resync standalone key fobs when only the remote functions — lock, unlock, panic — have failed, which often costs less than a full key replacement.
