A circuit inside the induction coil emits a signal when the transponder is placed in the an ignition barrel. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer inside the car recognizes the signal as being correct it will turn off the vehicle immobilizer, allowing the engine to 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 reprogram car key won't be allowed to operate.

When a car is connected with a specific fob it will only accept signals from the device that is associated with it.
