When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out an electrical signal. 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 detects the signal as correct it will turn off the vehicle immobilizer to allow the engine start. If the vehicle does not recognize the transponder signal as the correct one, it will stop the engine from starting and will alert you by flashing its lights and sounding a siren.

The receiver compared this information with the 'allowed' signals inside the fob, and either opens or locks the door. If the data does not match the signals, the car will not be allowed to operate. Once the car is linked with a specific fob, it will only receive signals from that device.
