Changing the Battery in Your
Mini One Key Key Fob
The key fob is a convenient way to lock or unlock your car from some distance. It can also activate your vehicle's panic button that can stop burglaries.
You can fix your fob by following a few steps. First, ensure that the battery is fresh. Then, remove it from the ignition by pressing the lock button three times rapidly.
Battery
The simplest way to fix the battery on your key fob is to replace it. The fob uses the small coin-shaped battery (CR2032, 2025) that can be located in the majority of general stores or home improvement stores and auto parts stores. Make sure to use a new battery. Old batteries can damage the circuit boards and become less useful.
You'll want to start by prying the fob open. It might be a bit tight but with the aid of a flat screwdriver you should be able to separate the halves. After that, slide the screwdriver in the seams on both sides of the fob, and then lift up a couple of clips that hold it in place. They can easily break so be cautious and take your time.
Reassemble the fob after replacing the battery, and test to see if it does what it is supposed to. If it isn't working after pressing the button several times, ensure that the contacts are clean. You can also test it with a spare fob to see if the problem is specific to your key. If not, there may be another reason behind the key fob not to function. For example it could be because the button is worn out. This would cause the button to work at times, not always.
Interference
The key fob is powered by a tiny transmitter that transmits signals of a short range to a receiver located in your car. Its function is to allow your vehicle to recognize the key fob and open its doors when you approach it, and then turn on when you push the ignition button.
The issue is that interference can occasionally interfere with this communication. If you charge your second-generation Apple Pencil while holding the fob (via iGeneration) it may prevent you from unlocking the vehicle.
Other electronic devices that use the same frequency as the fob may also interfere with its signal. This could include garage door openers and tire-pressure monitoring systems. Even a transmitter inside your home could be causing interference, but this isn't easy for an expert to test.
It's possible that your fob needs to be reset. The transmitter inside your key fob has to be recognized by

The fobs will typically need to be reset when they are removed or replaced, or when you purchase a replacement or, in certain cases the battery is changed.

The issue can be resolved by replacing the battery which is cheap and easy to locate at a hardware store or big-box retailer.

The fob should also not be 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'll need to clean it using isopropyl alcohol, or an electronic cleaner prior to putting in an entirely new battery.
Once the old battery is replaced, it is a good idea to test the function of the fob before driving the car. Check the voltage of the new battery with a voltmeter to ensure it's safe.
