The chip emits an unintentional radio signal when it is activated by an electromagnetic field. The signal is then taken up by an antenna that is attached to the ignition barrel. The computer system in the vehicle will then confirm that the chip in the key's transponder is the right one for your car.

The signal is received by the chip which then transmits a signal to the vehicle. If the car's computer recognizes this signal as being the right one, it will disable the immobilizer on the vehicle and allow the engine to start.

The receiver then compares this information to the signals that are allowed in the fob and then either opens or locks the door. If the data does not match, the car will not be allowed to operate.

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