When activated by an electro-magnetic field the chip emits a low-level signal. The signal is then taken up by an antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to confirm that the transponder chip inside the key is the right one for your specific vehicle.

A circuit within the induction coil will emit a signal when the transponder is put into an ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer in the car is able to recognize the signal as correct, it will disable vehicle immobilizer, allowing the engine to start.

If the vehicle doesn't recognize the transponder as the correct signal, it will not start the engine and will alert you with flashing lights and a siren.

The receiver compared this information with the signals that are allowed inside the fob, and either opens or closes the door. If the information does not match, the car will not be allowed to operate.

Once the car is paired with a specific fob it will only receive signals from that specific device. Other fobs won't work with the car, even if they appear like. This helps to protect the integrity of the vehicle's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.

This is because preparing the replacement fob is a process that requires technological and security expertise which can only be obtained in the dealer service department. However, some aftermarket fobs typically for older models with less sophisticated systems -- can be programmed by the consumer without the need of a dealership.
