Battery
The battery you use in your key fob is among the easiest solutions.

If it still doesn’t work, try pressing the button several times and checking that the contacts are in good order.

If it is not, there could be another reason for the key fob to not work. It could be due to a worn button, for instance. This would make the button function occasionally and not always.
Interference
The key fob is powered by a small transmitter that transmits an extremely short-range signal to a receiver inside your car. Its primary function is to allow your car to recognize the fob and unlock its doors when you approach it and start when you press the ignition button in.
Interference can occasionally interfere with communication. For instance, if have your second-generation Apple Pencil charged while you’re holding the fob, it might stop you from unlocking the car (via iGeneration).
Other electronic devices operating on the same frequency could also interfere with the fob’s signal. This could include garage door openers as well as tire-pressure monitoring systems. It’s possible that an RF transmitter inside your home might be interfering with the fob’s signal although this would be difficult to determine without an expert test.
It’s possible that your key fob is simply reprogrammed. This requires the transmitter on your fob to be identified by the receiver in your mini cooper key programming, and a unique code is assigned to each pairing. Fobs must be reprogrammed when they are removed from the system or replaced, either after you purchase a new one and in certain cases when the battery is changed. To reprogram a fob, follow the directions in the owner’s guideline or ask a dealer for assistance.

It is also crucial to ensure that the fob is not exposed to soapy or water residue. Water will often cause corrosion, which can interfere with the circuit board. If this is the situation you’ll need to wash the board with isopropyl, or an electronic cleaner prior to installing a new battery.
After the battery has been replaced, it’s an excellent idea to test the fob’s function before driving the car. Verify the voltage of the new battery with an voltmeter to make sure it is secure.
