The circuit in the induction coil will emit a signal when the transponder is inserted into ignition barrel. The signal will then get absorbed 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 turn off the vehicle immobilizer and allow the engine to begin.

The receiver compares this information to the signals that are allowed in the fob and then either opens or locks the door. If the data doesn't match an chirping sound is heard and the car isn't allowed to operate.
