Changing the Battery in Your Mini Key Fob
The key fob is an easy method to lock and unlock your car from the distance. It also allows you to activate your car's panic button that can stop burglaries.
If your device ceases to function, it can be fixed by following a few steps. Make sure the battery is new. Remove the battery from the ignition, and then press the lock button quickly three times.
Battery
The most straightforward way to repair the battery of your key fob is to replace it. The fob has a tiny coin-shaped 3V battery (CR2032 or CR2025) that is generally available in general stores as well as home improvement shops and even some auto parts stores. You should use a new battery. Batteries that are old can damage the circuit boards and are no longer useful.
Begin by removing the fob. It might be a bit tight but with the help of a flat screwdriver, you will be able to break the two halves. Attach the screwdriver to the seams on both sides of the fob and lift the clips that secure it. They are very easy to break, so proceed slowly and with care.
Reassemble the fob after replacing the battery and examine it to determine if the device does what it is supposed to. If it's not working, try pressing the button a few times before confirming that the contacts are clear. You could also try the fob with a spare to see if the problem is not specific to the key. If not, there could be another reason for the key fob to not function. For example it could be because the button is worn out. This would only cause the button to operate only occasionally, not all the time.
Interference
The key fob is powered by a tiny transmitter that transmits a short-range signal to a receiver located in your car. Its primary function is to permit your car to recognize the key fob, open its doors as you approach it, and begin when you push the ignition button.
Interference may sometimes hinder communication. For instance, if you have your second-generation Apple Pencil charged while you're holding the fob, it may prevent you from unlocking the car (via iGeneration).
Other electronic devices that operate on the same frequency could also interfere with the fob's signal. This includes garage door openers and tire pressure monitoring systems. Even g28carkeys.co.uk in your home could be causing interference, but this is difficult for professionals to test.
Your key fob may also require reprogramming. This requires the transmitter inside your fob to become recognized by the receiver inside your Mini and a unique code is assigned to each pairing. Fobs usually need to be reset when they are removed or replaced, if you purchase a replacement or, in rare cases the battery is changed. To reprogram a fob, follow the directions in the user's manual of your device or contact a dealer for assistance.

Modern electronic key fobs provide convenience and performance over traditional manual keys, however they are also susceptible to being damaged. A defective chip is one of the most frequent issues that can stop your key fob from functioning properly. Fortunately, it's usually an easy fix.

The fob should also not be exposed to water or soapy residue. Water can cause corrosion and affect the circuitry. If this is the case, you will have to wash it using isopropyl alcohol, or an electronic cleaner prior to installing the new battery.
When the old battery is replaced, it's an excellent idea to test the function of the fob before driving the vehicle. With a voltmeter, test the voltage of the replacement battery to see if it is at an acceptable level. If not, you could have to replace the entire remote chip.
