When it is activated by an electro-magnetic field the chip emits a low-level signal. The signal is taken up by an antenna that is attached to the barrel of ignition. The computer system of the vehicle will then confirm that the transponder chip of the key is the right one for your car.

When the transponder key is inserted in 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 inside the car is able to recognize the signal as being correct it will turn off the car immobilizer to allow the engine start.
If the car does not recognize the transponder signal as being the right one, it will keep the engine from starting and will notify you by flashing its lights and sounding an alarm.

The receiver compares this information with the 'allowed' signals stored in the fob and then either opens or closes the door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't able to operate.
Once the car is associated with a particular fob, it can only receive signals from the device. Other fobs will not work with the car, even though they appear identical.
