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

If the information doesn't match the signals, the car will not be allowed to run.

Once the car is connected to a specific fob, it only accepts signals from that device. Other fobs won't work with the car, even if they appear similar. This protects the integrity of the computer system that runs the vehicle and stops unauthorised key fobs from taking control of it.
