Battery
Change the battery in your key fob is among the easiest solutions. The fob uses a small coin-shaped 3V battery (CR2032 or CR2025) which is typically accessible in general stores as well as home improvement shops and some auto parts stores. Use a brand new battery. Old batteries can damage the circuit boards and become less useful.
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. Then, insert the screwdriver into the seams on both sides of the fob, and then lift up a couple of clips that hold it in place. These can be easily damaged so be cautious and take your time.
After replacing the battery, reassemble the fob and check to see if everything is functioning according to plan. If it still doesn't work try pressing the button a few times and checking that the contacts are clear. You can also try it with an additional key fob to determine whether the issue is specific to a particular key. If not, there could be a different reason for the key fob not to function. For instance it could be because the button is worn out. This would only make the button work occasionally but not constantly.
Interference
The key fob is powered by a tiny transmitter that sends out signals of a short range to a device in your car. Its goal is to enable your vehicle to recognize the key fob, unlock its doors when you come close to it, and then start when you press the ignition button.
Interference may sometimes hinder communication. If you charge your second-generation Apple Pencil while holding the fob (via iGeneration) it could block you from unlocking the vehicle.
Other electronic devices operating on the same frequency may also interfere with the fob's signal. This can include garage door openers and tire pressure monitoring systems. Even a transmitter in your home could be interfering with the tire pressure, but this isn't easy for an expert to test.
Your key fob might need to be reprogrammed. The transmitter inside your key fob must be recognized by the Mini's receiver. A unique code is then generated for each pairing. Fobs typically need to be programmed after being disconnected or replaced, when you purchase a replacement or, in rare cases when the battery is changed. Follow the directions in your owner’s manual to change the programming of a key fob. You can also ask a dealer for assistance.

The fob should not be exposed to water or soapy residue. Water will often cause corrosion, which could cause issues with the circuit board. If this is the case it is necessary to clean the board with isopropyl, or an electronic cleaner prior to installing the new battery.
It is a good practice to test the function of the fob prior to operating the vehicle. Using a voltmeter, check the voltage of the replacement battery to see if it is at a safe level. If not, you may need to replace the entire remote chip. A certified dealer technician will assist in determining the best solution for your vehicle.
