If the information does not match the signals, the car will not be allowed to run.
Once the car is paired with a specific fob, it will only accept signals from that specific device. In turn, other fobs will not work with the vehicle even if they appear similar. This safeguards the integrity of the computer system that runs the vehicle and stops unauthorized key fobs gaining control over it.
