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 fitted around the ignition barrel of your vehicle. The computer system of the vehicle will then confirm that the chip in the key's transponder is the correct one for your car.
This prevents the vehicle from starting by either hot-wiring or by tampering. The chip inside the key also proves that you are the genuine owner of the vehicle. This will help reduce car theft.

When the transponder key is inserted into 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 car's computer recognizes this signal as being the correct one, it will turn off the vehicle immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder signal as the proper one, it will prevent the engine from starting and will alert you by flashing its lights and sounding a siren.

The receiver then compares this information with the 'allowed' signals stored on the fob and either opens or locks the door. If the information does not match the fob's information, the car won't be allowed to run.
After the car has been associated with a particular fob, it can only receive signals from that device. Other fobs won't work with the car, despite the fact that they appear similar.
