When it is activated by an electromagnetic field the chip emits a low-level signal. This signal is then taken up by the antenna that is fitted around the barrel that controls your ignition in your car. This allows the computer in your vehicle system to determine if the transponder chip that is in the key is the correct one for the car you have.

This stops the vehicle from being started by hot-wiring, or by altering the key. The chip in the key also proves that you are the genuine owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer onboard the car detects the signal as correct, it will disable vehicle immobilizer, allowing the engine to start.

If the car doesn't recognize the transponder as the correct signal, it will not start the engine and alert you with flashing lights and siren. This system is designed to deter people from tampering with the vehicle. However, it is not an unbreakable security measure.

The receiver compared the information with the permitted signals stored in the key fob and then locks or opens the car door. If the data doesn't match an chirping sound is heard and the car isn't permitted to operate.

After the car has been connected to a specific fob, it only accepts signals from that device. Other fobs will not work with the car, even though they appear like. This safeguards the integrity of the computer system that runs the car and prevents the use of unauthorized key fobs to gain control of it.

This is due to the fact that preparing the replacement fob is a process that requires technological and security expertise that is only available in the dealer service department. Certain aftermarket fobs, typically those from older models that have less sophisticated systems can be programmed with out the need for a dealership.
