A circuit within the induction coil emits an electrical signal when the transponder is placed in the an ignition barrel. The signal will then get absorbed by the chip, causing it to send a signal back to the car. If the computer inside the car recognizes the signal as valid it will turn off the vehicle immobilizer to allow the engine start.

The receiver compares the information with the 'allowed signals' stored on the key fob and then opens or locks the car's door. If the data doesn't match an chirping sound is heard and the car isn't permitted to operate.
Once the car is linked with a particular fob, it will only receive signals from that device. Other fobs will not work with the car, even though they look similar. This ensures the security of the computer system that runs the car and blocks unauthorised key fobs from taking control over it.
