Chevrolet Car Key Replacement: What Type of Key Does Your Chevy Use?
Chevrolet has used several generations of key technology across its lineup, and knowing which type you have is the first step to getting a replacement made correctly. Older Chevy models use a traditional double-sided cut key with no electronics — straightforward to duplicate if you have a working copy, but requiring impressioning or decoding from the lock if all keys are lost. Models from the late 1990s onward typically use a transponder key, which contains a small chip in the plastic head that communicates with the vehicle's immobilizer. If the chip is absent, cloned incorrectly, or not programmed to your specific vehicle, the engine will crank but refuse to start — a detail that trips up owners who assume a hardware-store copy will work.
Newer Chevrolet trucks and SUVs — including the Equinox, Traverse, and full-size Tahoe — use key fobs that combine remote locking functions with a switchblade or separate emergency blade. The Blazer and Blazer EV, along with several other recent Chevy models, use proximity smart keys that only need to be present in the cabin to allow push-button starting. Each technology requires different equipment to cut, clone, or program, and our technicians arrive stocked with the tools and key blanks to handle all of them. If you are unsure which type your Chevy uses, simply call (973) 833-3217 and we can identify the correct key type from your year, make, and model before we even dispatch.
