This signal is then amplified by the specific antenna that is fitted around the barrel that controls your ignition in your vehicle.

When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal will then get received by the chip, causing it to transmit a signal back to the car. If the computer on the car recognizes this signal as the correct one, it will shut down the vehicle immobilizer and allow the engine to start.

The receiver compared the information with the 'allowed signals' that are stored on the key fob and then opens or locks the car door. If the information doesn't match, a chirping sound is heard and the car isn't allowed to function.

Once the car has been connected to a specific fob, it only accepts signals from the device. Other fobs will not work with the car, despite the fact that they appear identical.
