When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out a signal. The signal will be absorbed by the chip, causing it to transmit a signal back to the car. If the computer inside the car detects the signal as correct it will turn off the vehicle immobilizer, allowing the engine to start.

If the information isn't in line, a chirping sound is heard and the car isn't allowed to function.


Once the car is connected to a specific fob, it can only receive signals from the device. Other fobs will not work with the car, despite the fact that they appear similar.
