Changing the Battery in Your Mini Key Fob
The key fob is an easy method to lock and unlock your vehicle from the distance. It can also activate the panic button on your car to deter break-ins.
If your device stops working you can fix it with some simple steps. Make sure the battery is brand new. Then, try taking it from the ignition by pressing the lock button three times quickly.
Battery
The most straightforward way to repair the battery in your key fob is to replace it. The fob has a small coin-shaped battery (CR2032 or the CR2025) It can be found in most general stores or home improvement stores and auto parts stores. Use a new battery. Old batteries can damage the circuit boards and are no longer useful.
You'll need to start by prying the fob open. You may have to employ a flat screwdriver in order to split the two halves. Then, you can insert the screwdriver into the edges of the fob to raise a couple clips that hold it. They are easily broken therefore, proceed slowly and with care.
After replacing the battery replace the fob, then test it to see if everything is functioning exactly as it should. If it's not working you can try pressing the button several times and verifying that the contacts are in good order. You could also try it with another key fob to determine whether the issue is confined to that particular key. If not, there may be another reason why the key fob isn't functioning. For example it could be because the button is worn out. This would only make the button function occasionally but not constantly.
Interference
The key fob is powered by a tiny transmitter that transmits signals of a short range to a receiver in your car. Its purpose is to allow your car to recognize the fob, and open its doors when you come close to it and to start when you push the ignition button within.
The problem is that interference can interfere with the communication. For instance, if 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 operating on the same frequency can also interfere with the fob's signal. This can include garage door openers as well as tire-pressure monitoring systems. It is also possible that an RF transmitter inside your home may interfere with the fob's signal, although this would be difficult to determine without a professional test.
Your key fob may also require reprogramming. This procedure requires the transmitter inside your fob to be identified by the receiver in your Mini, and a unique code is assigned to each pairing. The fobs will typically need to be reset when they are disconnected or replaced, when you purchase a new one or, in rare cases the battery is changed. To reprogram a fob follow the steps in the owner's manual or contact a dealer for assistance.
Faulty chip
Modern electronic key fobs offer more convenience and functions than traditional manual keys. However, they are also more susceptible to damage. A defective chip is among the most frequent issues that could stop the key fob from working properly. Luckily, this is usually an easy fix.
If your fob is constantly failing to turn on your car, this is an indication that the chip is defective. The problem can usually be fixed by replacing the battery which is cheap and easy to locate at a hardware store or big-box retailer. Be sure to buy the right replacement battery compatible with your specific model of car to avoid recurring problems.
It is also crucial to ensure that the fob isn't exposed to water or soapy residue. Water is a common cause of corrosion, which can interfere with the circuit board. If this is the situation you'll need to wash the board with isopropyl or electronic cleaner prior to installing an entirely new battery.
It is a good idea to test the function of the fob prior to driving the vehicle. Test the voltage of the new battery using an voltmeter to make sure it's secure. If not, you might have to replace the entire remote chip. A qualified dealer technician can help determine the best solution for your vehicle.
