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 attached to the ignition barrel of your vehicle. This allows the computer in your vehicle system to confirm that the transponder chip that is in the key is the correct one for the car you have.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the car's computer recognizes this signal as being the right one, it will shut down the immobilizer on the vehicle and allow the engine to start.
If the car isn't able to recognize the transponder as the correct signal, it won't start the engine, and will alert you with flashing lights and siren. This feature is designed to discourage people from tampering with the vehicle. However, it is not an absolute security measure.

The receiver compares the information with the permitted signals stored on the key fob and then locks or opens the car door. If the information doesn't match, the car will not be allowed to operate.
After the car has been connected to a specific fob, it will only accept signals from that device. Other fobs will not work with the car, even though they appear like.
