Battery
The most straightforward way to repair the battery on your key fob is to replace it. The device uses a small coin-shaped 3V battery (CR2032 or CR2025) that is easy to find in general stores, home improvement shops, and a few auto parts stores. Make sure to use a new battery. Old batteries can harm the circuit boards and cease to be useful.
You'll need to start by opening the fob. It might be a bit tight but with the aid of a flat screwdriver you should be able separate the two halves. Then, insert the screwdriver into the seam on all sides of the fob and lift a couple of clips that hold it. These can be easily damaged, so be careful and take your time.
Reassemble the fob after replacing the battery, and test to determine if it works as it should. If it doesn't function after pressing the button several times, ensure that the contacts are clean. It is also possible to test it with another key fob to determine whether the issue is specific to the specific key. If not it could be another reason why the key fob isn't functioning.

Interference
The key fob is powered by a tiny transmitter that sends out signals of a short range to a receiver in your car. https://www.thekeylab.co.uk/mini-car-keys/ is to enable your car to recognize the key fob and open its doors when you come close to it, and begin when you press the ignition button.
The problem is that interference can occasionally interfere with this communication. For example, if you are using your second-generation Apple Pencil charged while you're holding the fob, it could prevent you from unlocking the car (via iGeneration).
Other electronic devices that operate on the same frequency as the fob can interfere with its signal. Garage door openers, or tire pressure monitoring devices may be affected. It's even possible that an RF transmitter inside your home could interfere with the fob's signal however, this is difficult to identify without an expert test.
It's also possible that the key fob is simply changed in its programming. This procedure requires the transmitter in your fob to be identified by the receiver in your Mini and a specific code is used for each pairing. The fobs will typically need to be reset when they are disconnected or replaced, when you buy a new one, and in some cases, when a battery is changed. To reprogram a fob follow the directions in the user's manual of your device or go to a dealer to seek assistance.
Chip that isn't working

If this is the situation you'll need to wash the board with isopropyl, or an electronic cleaner prior to installing a new battery.
Once the old battery is replaced, it is recommended to test the fob's functionality before driving the car.
