If the data does not match, the car will not be allowed to drive.
Once the car has been associated with a particular fob, it will only accept signals from that device. Other fobs will not work with the car, even though they look like. This ensures the security of the computer system that runs the car and prevents unauthorised key fobs from taking control over it.
The majority of newer dealerships will only accept cars that have original fobs, or genuine replacements sold by the manufacturer. The reason for this is that the only place with the experience to design an appropriate replacement fob is a dealer's service department.
