Why Is It So Useful? When COVID-19 Is In Session
Changing the Battery in Your Mini Key Fob

The key fob is a handy way to lock or unlock your vehicle from a distance. It also allows you to activate the panic button on your vehicle, which can deter break-ins.

If your device ceases to function It can be fixed by following a few simple steps. Make sure that the battery is brand new. Remove the battery from the ignition, and then press the lock button fast three times.

Battery

Change the battery in your key fob is one the most straightforward fixes. The key fob is powered by a small coin-shaped battery (CR2032, and CR2025), which is easily found in most general stores as well as home improvement stores and auto parts stores. Use a new battery. Old batteries can damage the circuit boards and cease to be useful.

Begin by removing the fob. It may be tight, but with the aid of a flat screwdriver, you will be able to break the two halves. Fit the screwdriver in the seams on both sides of the fob, and lift the clips that hold it. They are easily broken so be cautious and take your time.

After replacing the battery replace the fob, then check to see if everything is functioning as it should. If it's not working try pressing the button a few times and verifying whether the contacts are clear. You can also test it with a spare fob to see if the problem is confined to your key. If it isn't, there may be another reason that the key fob isn't working. It could be a worn-out button, as an example. This would only trigger the button only occasionally, not all the time.

Interference

The key fob uses tiny transmitters to transmit the short-range radio signal to a receiver within your vehicle. Its function is to permit your car to recognize the fob and unlock its doors when you approach, as well as start when you hit the ignition button inside.

The issue is that interference can occasionally interfere with that communication. For example, if you have your second-generation Apple Pencil charged while you're holding the fob, it might stop you from unlocking the car (via iGeneration).

Other electronic devices operating on the same frequency can also interfere with the fob's signal. This can include garage door openers and tire-pressure monitoring systems. Even a transmitter in your home could be causing interference with the tire pressure, but this is not easy for a professional to test.

Your key fob could require reprogramming. The transmitter inside the fob you have purchased must be recognized by Mini's receiver. A unique code is then generated for each pairing. Fobs need to be reprogrammed after being disconnected or replaced, after purchasing a new one or in some cases, when the battery is replaced. To reprogram a fob follow the steps in the user's manual of your device or contact a dealer for assistance.

Chips that aren't working

Modern electronic key fobs offer convenience and functionality over traditional manual keys, however they can also be more vulnerable to damage. A malfunctioning chip is among the most common issues that can stop your key fob from working properly. Luckily, this is usually an simple fix.

If your fob is continually failing to turn on your car, it's a sign that the chip is defective. 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 future problems make sure to purchase an appropriate battery with your car model.

It is also essential to ensure that the fob is not exposed to water or soapy residue. Water will often cause corrosion, which can cause problems with the circuit board. If this is the case you'll have to clean the board with isopropyl or an electronic cleaner prior to installing the new battery.


When the old battery is replaced, it's recommended to test the function of the fob prior to driving the car. With a voltmeter, test the voltage of the replacement battery to see if it is at a safe level. If not, it could be necessary to replace the entire chip inside the remote. A certified technician from a dealer can assist in determining the best solution for your vehicle.
