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

Once the car has been connected to a specific fob, it only accepts signals from the device. Other fobs won't work with the car, even if they appear similar. This is to safeguard the integrity of the vehicle's computer system and prevent unauthorized key fobs from gaining control of the vehicle.
