The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is then absorbed by a special antenna that is attached to the ignition barrel. The computer system of the vehicle can then verify that the key's transponder chip is the right one for your car.
This stops the vehicle from starting by hot-wiring, or by tampering. The chip inside the car key ensures that the owner is the one who is the owner of the vehicle. This helps to reduce the risk of theft from your car.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out the signal. The signal is received by the chip which then transmits a signal the vehicle. If the computer inside the car is able to recognize the signal as valid it will turn off the car immobilizer to allow the engine start.
If the vehicle does not recognize the transponder signal as the proper one, it will keep the engine from starting and will notify you by flashing its lights and sounding an alarm.

The receiver compared the information with the 'allowed signals' that are stored in the key fob and then opens or locks the car door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't permitted to operate.
Once the car is paired with a specific fob, it will only accept signals from that device. In turn, other fobs will not work with the vehicle, even though they look the same. This safeguards the integrity of the computer system in the vehicle and stops the use of unauthorized key fobs to gain control over it.
The majority of newer dealerships will only deal with vehicles that have original fobs or genuine replacements supplied by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security expertise that is only available in the dealer service department.
