The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal is then absorbed by the special antenna that is attached to the barrel that controls your ignition in your car. This allows the car's computer system to verify that the transponder chip inside the key is the right one for the car you have.

The circuit in the induction coil will emit signals when the transponder is put into ignition barrel. The signal will be absorbed by the chip and cause it to transmit a signal to the car.

The receiver compared this information to the signals that are allowed on the fob and either locks or opens the door.

When a car is connected with a specific fob, it will only accept signals from that specific device. This means that other fobs won't work with the vehicle even though they look the same.
