Old batteries can cause damage to the circuit boards and cease to be useful.

After replacing the battery, reassemble the fob and test it to see if everything is functioning just as it should. If it still doesn't work try pressing the button several times and ensuring that the contacts are in good order. You could also try it with a spare key fob in order to determine whether the issue is limited to that particular key. If it isn't, there may be another reason that the key fob isn't functioning. For example, it could be that the button is worn out. This would only make the button work infrequently and not always.

Interference

The key fob is powered by a tiny transmitter that sends out the signal in a short distance to a receiver located in your car. Its goal is to enable your car to recognize the fob and unlock its doors when you come close to it and to start when you press the ignition button inside.

Interference can interfere with communication. For instance, if have your second-generation Apple Pencil charged while you're holding the fob, it can prevent you from unlocking the car (via iGeneration).

Other electronic devices that use the same frequency as the fob can also interfere with its signal. Garage door openers, or tire pressure monitoring devices can also be affected. Even a transmitter inside your home could be causing interference with the tire pressure, but this is not easy for professionals to test.

Your key fob might need to be reprogrammed. The transmitter on the key fob needs to be recognized by Mini's receiver. A unique code is then used for each pairing.
