When it is activated by an electro-magnetic field the chip emits a low-level signal. The signal is then received by a specific antenna attached to the ignition barrel. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the right one for your car.
This is what prevents hot-wiring or tampering with the vehicle's ignition system to start it. The chip inside the key verifies that the owner is the person who is the owner of the vehicle. This will help reduce car theft.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal will then get taken up by the chip, causing it to transmit a signal to the car. If the onboard car computer recognizes this signal as the correct one, it will disable the vehicle's immobilizer and allow the engine to begin.
If the vehicle does not recognize the transponder signal as being the correct one, it will prevent the engine from running and will alert you by flashing its lights and sounding siren. This is designed to deter people from trying to alter the vehicle, but it isn't a foolproof security measure.

If the information doesn't match the signals, a chirping sound can be heard and the car isn't allowed to function.
Once the car is linked with a specific fob it will only receive signals from that device. Other fobs will not work with the car, despite the fact that they appear like.
