Transponder Chip Keys

If you own a vehicle from the last two decades or so, the odds are that it requires an transponder chip key to start. This technology is designed to prevent theft of cars by utilizing an encrypted signal that only the car's onboard computer can discern. The key is equipped with the same microchip used in military aircraft. The chip communicates with a vehicle's onboard computer system via an oblique cylinder antenna.

The key also has copper wire that's connected to the microchip. This wire transmits a message to the onboard computer in the car when you turn the key into the ignition. The onboard computer then responds by allowing the engine to start. If the code is valid, it will stay on and the car won't shut off or lock.

Some Mazda keys require programming (transponder and remote/fob keys). They can only be programmed by an automotive locksmith. Certain keys are not required for programming. Other keys do not require Coding.

Keys for Keyless Entry Systems
