The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal is then received by a specific antenna that is attached to the ignition barrel.

A circuit within the induction coil emits a signal when the transponder is inserted into ignition barrel. The signal is received by the chip which sends a signal to the vehicle. If the computer inside the car detects the signal as correct it will turn off the vehicle immobilizer, allowing the engine to start.

The receiver compared this information with the 'allowed' signals stored on the fob and either opens or closes the door. If the information doesn't match, the car will not be allowed to drive.

Once the car is paired with a specific fob it will only receive signals from that specific device. This means that other fobs won't be able to work with the vehicle, even though they look the same.
