When it is activated by an electro-magnetic field, the chip emits a low-frequency signal. This signal is then absorbed by a special antenna that is attached to the ignition barrel. This allows the car's computer system to verify that the transponder chip in the key is the correct one for your specific vehicle.

The circuit in the induction coil emits signals when the transponder is inserted into ignition barrel. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer in the car is able to recognize the signal as valid it will turn off the car immobilizer so that the engine can start.
If the vehicle does not recognize the transponder signal as being the right one, it will stop the engine from starting and will alert you by flashing its lights and sounding siren.

The receiver compares this information to the signals that are allowed in the fob and then either locks or opens the door. If the information doesn't match the fob's information, the car won't be allowed to drive.
Once the car is associated with a particular fob, it can only receive signals from that device. This means that other fobs will not work with the vehicle even if they have the same appearance. This helps to protect the integrity of the car's computer system and to prevent unauthorised key fobs from taking control of the vehicle.
