If the information does not match the signals, the car will not be allowed to operate. When a car is connected with a specific fob, it will only receive signals from that specific device. Other fobs won't work with the car, even if they appear identical. This protects the integrity of the computer system that runs the vehicle and stops unauthorized key fobs gaining control over it.
