The fob uses the small coin-shaped battery (CR2032, CR2025) that can be located in the majority of general stores, home improvement stores, and auto parts stores. Make sure you get a brand new battery -older batteries are typically not useful anymore and could damage the circuit board.

For instance, it could be that the button is worn out. This would cause the button to operate only occasionally, not all the time.

Interference

The key fob has a small transmitter to send the short-range radio signal to a receiver inside your vehicle. Its function is to permit your car to recognize the fob and then open its doors when you are near it and start when you press the ignition button inside.

The problem is, interference can sometimes hinder the transmission. For instance, if are using your second-generation Apple Pencil charged while you're holding the fob, it can stop you from unlocking your car (via iGeneration).

Other electronic devices that operate on the same frequency as the fob may interfere with its signal. Garage door openers and tire-pressure monitoring devices could be affected. It's possible that an RF transmitter within your home might interfere with the fob's signals, however, this is difficult to determine without an examination by a professional.

Your key fob may also require reprogramming. This requires the transmitter on your fob to be identified by the receiver in your mini cooper key fob programming and a specific code is used for each pairing. Fobs must be reprogrammed after they are disconnected or replaced, after you buy a new one or in some cases, when the battery is changed.

The issue can be repaired by replacing the battery which is affordable and easy to find at the hardware store or a big-box retailer. Make sure you buy the right replacement battery compatible with the model of your car to avoid further problems.

It is also essential to make sure that the fob is not exposed to water or soapy residue. Water can cause corrosion and affect the circuitry. If this is the case, you'll have to wash it by using isopropyl or electronic cleaner before putting in a new battery.

After the old battery has been replaced, it's an excellent idea to test the function of the fob before driving the car. Using a voltmeter, check the voltage of the new battery to determine if it is at an acceptable level. If not, it might be necessary to replace the entire chip inside the remote.
