Car Key Replacement

Car Key Replacement in San Jose

Most cars on San Jose and South Bay roads use one of a few key systems. Older and base models often carry a basic transponder key with a chip in the head that the car must recognize to start. Many newer vehicles use a remote head key or flip key that combines the transponder, cut blade, and lock/unlock buttons in one unit. Higher trims and recent model years frequently use a proximity smart key with push-to-start, where the fob stays in your pocket and the car detects it. Whether a given car supports push-to-start depends on the exact year, make, and model.

Behind all of these is the immobilizer, an anti-theft system that lets the engine run only when it reads an approved key or fob. That is why a replacement has to be both cut to your locks and electronically programmed to your vehicle, not just copied. You'll see a wide mix of makes and models around the valley, from commuter sedans to SUVs and pickups, and key systems vary widely between them.
