When activated by an electro-magnetic field, the chip emits a low level signal. This signal then gets taken up by the antenna that is positioned around the ignition barrel of your car. This allows the car's computer system to confirm that the transponder chip in the key is the correct one for your specific vehicle.

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal is received by the chip which then transmits a signal the vehicle. If the onboard car computer recognizes this signal as the right one, it will turn off the immobilizer on the vehicle and allow the engine to start.
If the vehicle doesn't recognize the transponder signal as being the correct one, it will keep the engine from starting and will alert you by flashing its lights and sounding an alarm.

The receiver compares this information to the 'allowed' signals on the fob and either locks or opens the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't allowed to operate.
Once the car is linked with a specific fob it will only accept signals from the device that is associated with it. Other fobs will not work with the car, even though they appear identical.
