Battery

The simplest way to fix the battery in your key fob is to replace it. The fob uses a small coin-shaped 3V battery (CR2032 or CR2025) which is typically easy to find in general stores or home improvement stores and a few auto parts stores. Be sure to use a new battery -older batteries are typically not useful anymore and could damage the circuit board.

Start by prying the fob open. It may be necessary to use a flat screwdriver separate the halves. Place the screwdriver through the seams on both sides of the fob and lift the clips that hold it. These are easily broken, so be careful and work slowly.

After replacing the battery then reassemble the fob and check to see if everything is working exactly as it should. If it isn't working after pressing the button multiple times, ensure that the contacts are clean. You could also try it using an additional key fob to determine whether the issue is specific to a particular key. If not it could be another reason for why your key fob isn't working. It could be a worn-out button, for instance. This would cause the button to function at times, not always.

Interference

The key fob uses tiny transmitters to transmit a short-range radio signal to a receiver inside your car. Its primary function is to permit your vehicle to recognize the key fob, open its doors when you come close to it, and then start when you push the ignition button.

The problem is that interference can interfere with that communication. If you charge your second-generation Apple Pencil while holding the fob (via iGeneration) it could stop you from unlocking your vehicle.

Other electronic devices that operate on the same frequency as the fob may also 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 causing interference however this is not easy for a professional to test.

Your key fob might need to be reprogrammed. This process requires the transmitter in your fob to become recognized by the receiver in your Mini and a unique code is used for each pairing. Fobs have to be reprogrammed after being disconnected or replaced, if you purchase a replacement and in certain cases when the battery is changed.

The issue is usually solved by replacing the battery, which is inexpensive and easy to locate at a hardware store or big-box retailer. To avoid problems in the future make sure to purchase an appropriate battery with your car model.

It is also crucial to make sure that the fob isn't exposed to water or soapy residue. Water is a common cause of corrosion, which could cause issues with the circuit board. If this is the case, you will need to clean it with isopropyl alcohol or an electronic cleaner before putting in an entirely new battery.

After the battery has been replaced, it is a good idea to test the fob's function prior to driving the car. Test the voltage of the new battery using an voltmeter to make sure it is secure. If not then it may be necessary to replace the entire chip in the remote. A certified technician from a dealer can determine the best option for you vehicle.
