Battery
The simplest way to fix your key fob's battery is to replace it. The fob has a tiny coin-shaped 3V battery (CR2032 or CR2025) that is generally available in general stores, home improvement shops, as well as some auto parts stores.

Start by opening the fob. It may be tight, but with the help of a flat screwdriver, you should be able separate the two halves. Then, you can insert the screwdriver into the seam on both sides of the fob to lift a couple of clips holding it in place. They are very easily broken so be careful and slow.
After replacing the battery replace the fob, then examine it to determine if everything is working exactly as it should. If it doesn't work, try pressing the button several times before confirming whether the contacts are clear.

For instance, it could be that the button is worn out. This could make the button work infrequently and not all the time.
Interference
The key fob is powered by a tiny transmitter that sends out the signal in a short distance to a receiver in your car. Its goal is to enable your car to recognize the key fob and open its doors as you approach it, and begin when you press the ignition button.
The issue is that interference can sometimes interfere with that communication. If you charge your second-generation Apple Pencil while holding the fob (via iGeneration) it may prevent you from unlocking your vehicle.
Other electronic devices that operate on the same frequency as the fob might interfere with its signal. This can include garage door openers as well as tire-pressure monitoring systems. Even a transmitter at your home could be interfering however this is difficult for professionals to test.
It's possible that your fob needs to be reprogrammed. This procedure requires the transmitter inside the fob to be recognized by the receiver in your Mini, and a unique code is assigned to each pairing. Fobs are typically reprogrammed when they're removed or replaced, if you buy a new one and, in some instances, when a battery is changed. Follow the directions in the owner's manual for how to program a key fob, or ask a dealer for assistance.

Once the old battery is replaced, it's an excellent idea to test the function of the fob prior to driving the car. Examine the voltage of new battery with an voltmeter and make sure it's safe.
