The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is absorbed by a special antenna attached to the ignition barrel. This allows the computer in your vehicle system to confirm that the transponder chip that is in the key is the correct one for the car you have.

If the onboard car computer detects this signal as the correct one, it will turn off the immobilizer on the vehicle and allow the engine to begin.

If the vehicle doesn't recognize the transponder signal as the proper one, it will stop the engine from starting and will alert you by flashing its lights and sounding an alarm. This feature is designed to deter people from trying to tamper with the vehicle, however it's not a 100% security measure.

When you press the button on a key fob the microchip sends a signal to the receiver inside the car with which it is paired. The receiver then compares this information to the 'allowed' signals in the fob and then either opens or closes the door. If the information isn't in line an chirping sound is heard and the car isn't permitted to function.

Once the car is linked with a particular fob, it will only receive signals from the device that is associated with it. Other fobs will not work with the car, even though they look like. This safeguards the integrity of the computer system in the vehicle and stops unauthorised key fobs from taking control of it.

This is because preparing the replacement fob is a process that requires technological and security expertise that is only available in the dealer service department. However, some aftermarket fobs -- usually those for older models with less sophisticated systems can be programmed by the consumer without the need of dealers.
