Transponder Keys
A lot of the time, in newer automobiles, transponder keys have an RFID microchip within the key that transmits a specific code to the car when it is placed in the ignition. It is designed to guard against theft by making sure that only the correct key can start the car. Contact your local dealership or locksmith for an example of this technology.
When the transponder is placed in the ignition, the key sends an electronic message to the chip inside the engine control unit (ECU) of the vehicle. The ECU is then able to determine whether the code contained in the key matches its own digital serial number. If it does it, the ECU removes the immobilizer, allowing the engine to start. If the code is not compatible, then the ECU will block the signal and prevent the engine from starting.
