This allows the computer in your vehicle system to verify that the transponder chip inside the key is the correct one for your specific vehicle.

A circuit within the induction coil will emit an electrical signal when the transponder is put into ignition barrel. The signal will then get absorbed by the chip, causing it to send a signal back to the car. If the computer inside the car is able to recognize the signal as being correct it will turn off the car immobilizer so that the engine can start.

The receiver compared this information to the 'allowed' signals stored inside the fob, and 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 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. This protects the integrity of the computer system of the car and prevents unauthorized key fobs gaining control of it.
