The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is then absorbed by the special antenna that is positioned around the ignition barrel of your car. This allows the computer in your vehicle system to determine if the transponder chip in the key is the right one for your specific vehicle.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil sends out the signal. The signal is taken up by the chip, which then transmits a signal the vehicle. If the onboard car computer recognizes this signal as the correct one, it will disable the vehicle's immobilizer and allow the engine to begin.

The receiver compared the information with the 'allowed signals' that are stored in the key fob and then locks or opens the car door. If the information doesn't match an chirping sound is heard and the car isn't allowed to function.
Once the car is linked with a specific fob, it will only receive signals from that device. In turn, other fobs will not work with the vehicle, even though they have the same appearance.
