When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out the signal. The signal will then get taken up by the chip, causing it to send a signal back to the car. If the computer on the car detects this signal as the correct one, it will turn off the vehicle immobilizer and allow the engine to start.

If the vehicle doesn't recognize the transponder signal as being the proper one, it will stop the engine from starting and will alert you by flashing its lights and sounding a siren. This function is designed to discourage those who would attempt to alter the vehicle. However it's not an unbreakable security measure.

When you press the button on your key fob the microchip inside sends an encoded code to the car's receiver it is linked to. The receiver compared the information with the 'allowed signals' that are stored in the key fob and then locks or opens the car's door. If the information isn't in line an chirping sound is heard and the car isn't permitted to function.

Once the car has been paired with a specific fob, it will only accept signals from that device. In turn, other fobs won't work with the vehicle even though they look the same. This safeguards the integrity of the computer system that runs the vehicle and stops the use of unauthorized key fobs to gain control of it.
