What is a transponder key, and why does it matter for my car's security?

A transponder key contains a small electronic chip that communicates with your vehicle's immobilizer — if the chip isn't recognized, the engine won't start, even with the correct mechanical cut. This layer of protection has been standard on most vehicles since the late 1990s and significantly reduces the risk of hot-wire theft. Sundial Locksmith can cut and program transponder keys for most makes and models; call (480) 525-7778 to find out if we support yours.
