Battery

Switching the battery on your key fob is among the most straightforward fixes. The key fob is powered by a tiny coin-shaped 3V battery (CR2032 or CR2025) that is usually easily found in general stores as well as home improvement shops and a few auto parts stores. Be sure to use a brand new battery -old batteries are usually not useful anymore and could cause damage to the circuit board.

It is recommended to begin by opening the fob. It may be necessary to use a flat screwdriver break the two halves. Attach the screwdriver to the seams on both sides of the fob, and lift the clips which hold it in place. They are very easy to break So, work slowly and carefully.

Reassemble the fob after replacing the battery, and examine it to determine if the device does what it is supposed to. If it doesn't function after pressing the button a few times, make sure that the contacts are clean. You could also try it with a spare fob to see if the problem is not specific to the key. If it is not, there could be another reason behind the key fob to not function. It could be due to a worn button, for instance. This could cause the button to work a few times and not all the time.

Interference

The key fob is powered by a small transmitter that transmits an extremely short-range signal to a receiver located in your car. Its primary function is to allow your car to recognize the fob, and open its doors when you come close to it and also start when you hit the ignition button inside.

The problem is, interference can occasionally interfere with that communication. For instance, if you are using your second-generation Apple Pencil charged while you're holding the fob, it could stop you from unlocking the car (via iGeneration).

Other electronic devices that use the same frequency as the fob may interfere with its signal. Garage door openers or tire-pressure monitoring devices may be affected. Even mini cooper key at your home could be causing interference with the tire pressure, but this is difficult for a professional to test.

It's also possible that your key fob simply needs to be modified. The transmitter in the key fob needs to be recognized by the Mini's receiver. A unique code is used for each pairing. Fobs usually need to be programmed after being disconnected or replaced, when you buy a new one and, in some instances when the battery is changed. Follow the directions in your owner’s manual to reprogram a key fob or consult a dealer.

The fob shouldn't be exposed to water or soapy residue. Water can cause corrosion and disrupt the circuitry. If this is the situation you'll need to wash the board with isopropyl and electronic cleaner prior to installing a new battery.

It is a good idea to test the operation of the fob before driving the vehicle. Test the voltage of the new battery using the help of a voltmeter to confirm that it's secure.
