Battery

If it isn't, there may be another reason for why your key fob isn't functioning. For instance, it could be that the button is worn out. This will only cause the button to work only occasionally, not all the time.

Interference

The key fob is powered by a tiny transmitter that sends out a short-range signal to a device in your car. Its purpose is to allow your car to recognize the fob and unlock its doors when you are near it and start when you press 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 could prevent you from unlocking the vehicle.

Other electronic devices that operate on the same frequency as the fob could interfere with its signal. This includes garage door openers and tire pressure monitoring systems. Even a transmitter in your home could be interfering, but this would be difficult for a professional to test.

Your key fob could require reprogramming. The transmitter on your key fob must be recognized by Mini's receiver. A unique code is then used for each pairing. Fobs typically need to be reprogrammed when they're removed or replaced, if you purchase a replacement or, in certain cases the battery is changed. Follow the directions in the owner's manual for how to change the programming of a key fob. You can also ask a dealer for help.

The issue is usually solved by replacing the battery, which is affordable and easy to locate at any hardware store or big box retailer. To avoid further problems, make sure you purchase a battery that is compatible for the car model you have.

The fob should not be exposed to water, or soapy residue. Water is a common cause of corrosion, which can cause interference with the circuit board. If this is the case, you will need to clean the circuit board using isopropyl alcohol, or an electronic cleaner prior to putting in a new battery.

When the old battery is replaced, it's recommended to test the function of the fob before driving the car.
