When activated by an electro-magnetic field, the chip emits a low-level signal.

A circuit inside the induction coil will emit a signal when the transponder is placed in the ignition barrel. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer onboard the car recognizes the signal as being correct, it will disable vehicle immobilizer, allowing the engine to start.

If the vehicle does not recognize the transponder signal as the correct one, it will prevent the engine from starting and will notify you by flashing its lights and sounding an alarm.

If the data doesn't match an chirping sound is heard and the car isn't allowed to function.

When a car is connected with a specific fob it will only accept signals from the device that is associated with it. In turn, other fobs won't work with the vehicle even though they appear similar.
