Make sure you use a new battery -old batteries are usually not good for anything and could cause damage to the circuit board.
Start by opening the fob. It might be tight, but with the help of a flat screwdriver, you will be able to break the halves. Place the screwdriver through the seams on both sides of the fob and lift the clips which hold it in place. They are very easily broken, so be careful and slow.

It could be due to a worn-out button, for instance. This would trigger the button at times, not always.
Interference
The key fob is powered by a tiny transmitter that sends out a short-range signal to a receiver inside your car. Its purpose is to allow your car to recognize the fob and unlock its doors when you approach it and also start when you hit the ignition button inside.
Interference can occasionally interfere with communication. If you charge your second-generation Apple Pencil while holding the fob (via iGeneration) it may prevent you from unlocking the vehicle.
Other electronic devices that utilize the same frequency as the fob can interfere with its signal. This could include garage door openers and tire pressure monitoring systems. A transmitter in your home could be interfering however this isn't easy for professionals to test.
The key fob might need to be reprogrammed. The transmitter on the fob you have purchased must be recognized by the Mini's receiver. A unique code is then created for each pairing. Fobs need to be reprogrammed after they have been disconnected or replaced, after you purchase a replacement or in some cases, when the battery is replaced. Follow the instructions in the owner's manual to reprogram a key fob or seek assistance from a dealer.

It is also important to ensure that the fob isn't exposed to soapy or water residue. Water can cause corrosion and affect the circuitry. If this is the case it is necessary to clean the board with isopropyl or 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 vehicle. Examine the voltage of new battery using an voltmeter to make sure it's secure.
