Changing the Battery in Your Mini Key Fob
The key fob is an easy option to lock and unlock your car from a distance. It can also activate your car's panic button, which can deter break-ins.

Battery
The simplest way to fix the battery in your key fob is to replace it. The fob uses a small coin-shaped 3V battery (CR2032 or CR2025) that is usually easy to find in general stores as well as home improvement shops and even some auto parts stores. Make sure you use a new battery -- old batteries are often not good for anything and can cause damage to the circuit board.
You'll need to start by prying the fob open. You may need to employ a flat screwdriver in order to split the two halves. Attach the screwdriver to the seams on both sides of the fob, and lift the clips that secure it. These are easily broken so be cautious and work slowly.
After replacing the battery, reassemble the fob and examine it to determine if everything is functioning exactly as it should. If it does not work after pressing the button several times, make sure the contacts are clean. You could also try it with a spare fob to see if the problem is specific to your key. If it isn't the case, there could be another reason that the key fob isn't functioning. It could be due to a worn button, for example. This would cause the button to work occasionally, not every time.
Interference
The key fob is a tiny transmitter to send an audio signal that is short-range to a receiver inside your car. Its purpose it to allow your car to recognize the key fob, open its doors when you approach it, and begin when you push the ignition button.
Interference may sometimes hinder communication. If you charge your second-generation Apple Pencil while holding the fob (via iGeneration), it could prevent you from unlocking your vehicle.
Other electronic devices operating on the same frequency can also interfere with the fob's signal. Garage door openers or tire-pressure monitoring devices can be affected. It's even possible that an RF receiver inside your home could interfere with the fob's signal however, this is difficult to diagnose without an expert test.
The key fob might require reprogramming. This requires the transmitter on your fob to become recognized by the receiver inside your Mini and a unique code is assigned to each pairing. Fobs are typically programmed after being removed or replaced, or when you purchase a new one or, in certain cases when the battery is changed. To reprogram a fob, follow the steps in the owner's guideline or ask a dealer for assistance.

To avoid any further issues, make sure you purchase the correct battery with the vehicle model you are using.
The fob shouldn't be exposed to water or soapy residue. Water is a common cause of corrosion, which can cause problems with the circuit board. If this is the situation you'll have to clean the board with isopropyl or an electronic cleaner prior to installing an entirely new battery.
When the old battery is replaced, it is recommended to test the function of the fob prior to driving the car.
