A Transponder chip is an RFID radio transmitter hidden in the key that talks to the cars computer through a wireless system confirming that the correct Key is in the ignition.
After the chip is verified the Cars Immobiliser system allows the car to start. There are different types of transponder chips for different makes and models and each type needs to be used to match the particular car. The best way to do this is by having a locksmith cut and program the key or taking the vehicle to a Gold Coast dealership.
