A circuit within the induction coil will emit signals when the transponder is placed in the the ignition barrel. The signal will be taken up by the chip and cause it to transmit a signal to the car. If the computer onboard the car recognizes the signal as correct it will turn off the car immobilizer to allow the engine start.

The receiver compared the information with the 'allowed signals' stored in the key fob, and then locks or opens the car door. If the data doesn't match an chirping sound is heard and the car isn't permitted to operate.
Once the car is paired with a specific fob, it will only accept signals from the device that is associated with it. Other fobs won't work with the car, even though they appear similar.
