This is a little plastic thing on the back of your key that houses a RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own. When it is activated by an electromagnetic field, the chip emits a low-level signal. The signal is then amplified by the specific antenna that is positioned around the ignition barrel of your vehicle.

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out a signal. The signal will then get absorbed by the chip, causing it to transmit a signal to the car. If the onboard car computer recognizes this signal as the right one, it will shut down the immobilizer on the vehicle and allow the engine to begin. If the vehicle does not recognize the transponder signal as being the proper one, it will keep the engine from starting and will notify you by flashing its lights and sounding siren.

Certain cars let you do this by yourself. However, the majority of newer models require you to visit a professional locksmith or dealer to program a new key fob or an additional one. When you press the button on your key fob the microchip inside sends a code to the car's radio that it is paired with. The receiver compared this information with the signals that are allowed in the fob and then either opens or locks the door. If the data does not match the fob's information, the car won't be allowed to run. When reprogram car key is connected with a particular fob, it will only accept signals from that specific device. Other fobs won't work with the car, despite the fact that they look identical.
