Battery
The simplest way to fix the battery of your key fob is to replace it. The fob has a small coin-shaped battery (CR2032 or the CR2025) and can be located in the majority of general stores, home improvement stores, and auto parts stores. Make sure to use a new battery -old batteries are usually no longer good for anything and can cause damage to the circuit board.
Start by opening the fob. It may be necessary to use a flat screwdriver to break the two halves. Place the screwdriver through the seams on both sides of the fob, and lift the clips that hold it. They are easy to break So, work slowly and carefully.
After replacing the battery, reassemble the fob and check to see if everything is functioning as it should. If it doesn't work you can try pressing the button several times and checking whether the contacts are clear. It is also possible to test it with a spare key fob to determine if the issue is isolated to a specific key. If it is not, there could be another reason for the key fob to not function. It could be due to a worn-out button, as an example. This could make the button work infrequently and not always.
Interference
The key fob is powered by a small transmitter that sends out an extremely short-range signal to a device in your car. Its function is to allow your vehicle to recognize the key fob, then open its doors when you are near it, and then turn on when you push the ignition button.
Interference can sometimes interfere with communication. For instance, if have your second-generation Apple Pencil charged while you're holding the fob, it could hinder you from unlocking your car (via iGeneration).
Other electronic devices that utilize the same frequency as the fob could interfere with the signal. Garage door openers and tire-pressure monitoring devices may be affected. It is even possible that an RF transmitter within your home might be interfering with the fob's signal, however, this is difficult to diagnose without the assistance of a qualified test.
Your key fob may also require reprogramming. This process will require the transmitter in the fob to be recognized by the receiver inside your Mini and a specific code is used for each pairing. Fobs have to be reprogrammed after they have been disconnected or replaced, after you buy a new one and, in some instances, when the battery is replaced. To reprogram a fob follow the instructions in the owner's guideline or contact a dealer for assistance.
