Battery
The most simple way to fix the battery on your key fob is to replace it. The device uses a small coin-shaped 3V battery (CR2032 or CR2025) that is usually easily found in general stores as well as home improvement shops and some auto parts stores. Use a brand new battery. Batteries that are old can damage the circuit boards and are no longer useful.
Start by prying the fob open. It may be necessary to employ a flat screwdriver in order to split the two halves. Install the screwdriver into the seams on both sides of the fob and lift the clips that hold it. They are easy to break therefore, take your time and work slowly.
After replacing the battery replace the fob, then check to see if everything is functioning according to plan. If it doesn't function after pressing the button several times, ensure that the contacts are clean. You can also try it with a spare key fob in order to determine if the issue is isolated to a specific key. If not, there may be another reason behind the key fob to not function. It could be a worn-out button, as an example. This would cause the button to function occasionally, not every time.
Interference
The key fob is powered by a tiny transmitter that sends out the signal in a short distance to a receiver inside your car. Its goal is to enable your car to recognize the key fob, then open its doors when you approach it, and then turn on when you press the ignition button.
The problem is that interference can occasionally interfere with the transmission. If you charge your second-generation Apple Pencil while holding the fob (via iGeneration), it could prevent you from unlocking the vehicle.
Other electronic devices operating at the same frequency can also interfere with the fob's signal. Garage door openers and tire-pressure monitoring devices could be affected. Even a transmitter at your home could be causing interference, but this is not easy for a professional to test.

Your key fob may also need to be reprogrammed. The transmitter in the fob you have purchased must be recognized by Mini's receiver. A unique code is then used for each pairing. Fobs typically need to be reprogrammed when they're removed or replaced, if you purchase a replacement and, in some instances the battery is changed. To reprogram a fob, follow the directions in your owner's manual or contact a dealer for assistance.

It is a good practice to test the functioning of the fob prior driving the vehicle. Using a voltmeter, check the voltage of the new battery to determine whether it is at a safe level.
