The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal is then taken up by an antenna attached to the barrel of ignition. This allows the vehicle's computer system to confirm that the transponder chip in the key is the right one for your specific vehicle.

The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer on the car detects this signal as the correct one, it will disable the vehicle's immobilizer and allow the engine to begin.
If the car isn't able to recognize the transponder as the correct signal, it will not start the engine and will notify you via flashing lights and siren. programming car key is designed to discourage people from trying to hack into the vehicle, but it isn't a foolproof security measure.

When you press the button on your key fob, the microchip inside transmits an encoded code to the car's radio that it is paired with. The receiver compares the information with the 'allowed signals' that are stored in the key fob, and then it opens or closes the car door. If the information isn't in line, a chirping sound is heard and the car isn't allowed to operate.
Once the car has been connected to a specific fob, it can only receive signals from the device. Other fobs won't work with the car, even if they look identical. This helps to protect the integrity of the car's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle.
