Battery

Switching the battery on your key fob is one of the most straightforward fixes.

Make sure you get an original battery -older batteries are typically not suitable for any purpose and can damage the circuit board.

Reassemble the fob after replacing the battery, and check to see if it works as it should. If it doesn't function after pressing the button several times, ensure that the contacts are clean. It is also possible to test it using an additional key fob to determine whether the issue is limited to the specific key. If it isn't then there could be a different reason for why your key fob isn't working. For instance it could be because the button is worn out. This would make the button work infrequently but not continuously.

Interference

The key fob has tiny transmitters to transmit an audio signal that is short-range to a receiver within your vehicle. Its primary function is to permit your car to recognize the key fob and open its doors as you approach it, and begin 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 prevent you from unlocking your vehicle.

Other electronic devices operating on the same frequency may also interfere with the fob's signal. This can 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 signal, though this would be difficult to determine without the assistance of a qualified test.

Your key fob may also require reprogramming. This process requires the transmitter in your fob to be recognized by the receiver in your mini cooper spare key and a distinct code is assigned to each pairing. Fobs must be reprogrammed when they are removed from the system or replaced, after you purchase a new one or in some cases, when the battery is changed.

If this is the case, you'll have to wash it using isopropyl alcohol, or an electronic cleaner prior to installing an entirely new mini Key fob battery.

When the old battery is replaced, it is an excellent idea to test the functionality of the fob before driving the vehicle. Check the voltage of the new battery with a voltmeter to ensure it's safe.
