When activated by an electro-magnetic field the chip emits a low-level signal. The signal is then taken up by an antenna that is attached to the ignition barrel. This allows the computer in your vehicle system to determine if the transponder chip in the key is the right one for your specific vehicle.

The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer inside the car detects the signal as correct it will turn off the car immobilizer, allowing the engine to start.

If the data does not match the signals, the car will not be allowed to run.

When a car is connected with a particular fob, it will only receive signals from the device that is associated with it. Other fobs won't work with the car, despite the fact that they appear like.
