When activated by an electro-magnetic field, the chip emits a low-frequency signal. This signal is then received by a specific antenna that is attached to the ignition barrel. This allows the vehicle's computer system to determine if the transponder chip that is in the key is the right one for the car you have.

This prevents the vehicle from being started by hot-wiring, or by tampering. The chip inside the key also confirms that you are the genuine owner of the vehicle. This helps to reduce the risk of theft from your car.

The signal will then get taken up by the chip and cause it to transmit a signal to the car. If the onboard car computer detects this signal as the right one, it will shut down the immobilizer on the vehicle and allow the engine to begin.

The receiver then compares this information with the 'allowed' signals on the fob and either opens or closes the door. If the data doesn't match, a chirping sound is heard and the car isn't permitted to operate.

Once the car is paired with a specific fob, it will only receive signals from the device that is associated with it. Other fobs will not work with the car, even though they appear identical.
