When it is activated by an electromagnetic field the chip emits a low level signal. The signal is then taken up by an antenna that is attached to the ignition barrel. The computer system in the vehicle is then able to verify that the key's transponder chip is the correct one for your car.

The signal will then get taken up by the chip and cause it to transmit a signal to the car. If the computer inside the car recognizes the signal as being correct it will turn off the vehicle immobilizer so that the engine can start.

The receiver then compares the data with the 'allowed signals' that are stored in the key fob, and then opens or locks the car's doors. If the information isn't in line the signals, a chirping sound can be heard and the car isn't permitted to operate.
When a car 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 similar.
