The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is then absorbed by the special antenna that is positioned around the barrel that controls your ignition in your vehicle. This allows the computer in your vehicle system to verify that the transponder chip that is in the key is the correct one for the car you have. This is what prevents hot-wiring or tampering with the ignition system of your vehicle to start it. The chip in the car key verifies that the owner is the person who owns the vehicle.

A circuit inside the induction coil will emit signals when the transponder is inserted into ignition barrel. The signal will then get taken up by the chip and cause it to transmit a signal to the car. If the computer on the car recognizes this signal as being the right one, it will shut down the vehicle's immobilizer and allow the engine to start. If the vehicle doesn't recognize the transponder signal as the proper one, it will keep the engine from running and will alert you by flashing its lights and sounding siren. This feature is intended to discourage people from attempting to alter the vehicle, but it is not a foolproof security measure.

Certain cars let you do this by yourself. However, most newer models require you to visit an expert locksmith or dealer in order for them program a replacement key fob or additional one. When you press the button on a key fob the microchip sends an indication to the receiver in the car with which it is linked. The receiver compared this information with the 'allowed' signals in the fob and then either opens or closes the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't allowed to operate. After the car has been connected to a specific fob, it only accepts signals from that device. In turn, other fobs won't be able to work with the vehicle, even though they have the same appearance. This protects the integrity of the vehicle's computer system, and also to stop unauthorized key fobs from gaining control of the vehicle. The majority of newer dealerships will only work with vehicles that have original fobs, or genuine replacements supplied by the manufacturer.
