Battery
The most simple way to fix the battery on your key fob is to replace it. The key fob uses a tiny coin-shaped battery (CR2032 or 2025) that can be found in a variety of general stores as well as home improvement stores and auto parts stores. Make sure to use a new battery. Old batteries can cause damage to the circuit boards and become less useful.
It is recommended to begin by opening the fob. It may be a bit tight, but with the aid of a flat screwdriver, you should be able separate the two halves. Then, fit the screwdriver into the seams on both sides of the fob to lift up a couple of clips holding it in place. These are easy to break so take your time and work slowly.
After replacing the battery, reassemble the fob and test it to see if everything is working as it should. If it does not work after pressing the button several times, make sure that the contacts are clean. You could also try it with a spare key fob to see if the problem is isolated to your key. If it isn't, there may be another reason that the key fob isn't working. It could be a worn-out button, as an example. This will only trigger the button at times, not always.
Interference
The key fob uses a small transmitter to send an audio signal that is short-range to a receiver inside your car. Its goal is to enable your car to recognize the key fob, unlock its doors when you come close to it and start when you press the ignition button.
The issue is that interference can sometimes hinder the transmission. For example, if you have your second-generation Apple Pencil charged while you're holding the fob, it might stop you from unlocking your car (via iGeneration).
Other electronic devices that operate on the same frequency could also interfere with the fob's signal. This could include garage door openers, as well as tire pressure monitoring systems. It is even possible that an RF transmitter inside your home could be interfering with the fob's signals, however, this is difficult to determine without the assistance of a qualified test.
It's also possible that your key fob needs to be modified. This procedure requires the transmitter inside the fob to be recognized by the receiver in your Mini and a distinct code is assigned to each pairing. Fobs typically need to be changed when they're removed or replaced, if you purchase a replacement and, in some instances when the battery is changed. To reprogram a fob follow the instructions in the owner's manual or go to a dealer to seek assistance.

The fob should also not be exposed to water or soapy residue. The presence of water can cause corrosion, which can cause interference with the circuit board. If this is the situation, you'll need to clean the board with isopropyl, or an electronic cleaner prior to installing the new battery.
After the battery has been replaced, it is recommended to test the fob's function before driving the vehicle. Check the voltage of the new battery using the help of a voltmeter to confirm that it is secure. If not, it could be necessary to replace the entire chip in the remote.
