3. Internal Electronic Failure
If the buttons no longer lock or open the doors, but the battery is fresh, the internal circuitry might have a damaged solder joint or a stopped working component.

Repair Path: Circuitry repair or reprogramming. Experts can sometimes resolder loose battery terminals or buttons. However, if the PCB is fried, a new programmed key is needed.
