Battery

The simplest way to fix the battery of your key fob is to replace it. The key fob uses a tiny coin-shaped battery (CR2032, and CR2025) It can be found in a variety of general stores as well as home improvement stores and auto parts stores. Be sure to use the latest batteryolder batteries are typically not useful anymore and can damage the circuit board.

Start by opening the fob. It may be a bit tight, but with the help of a flat screwdriver you should be able to separate the two halves. Fit the screwdriver in the seams on both sides of the fob, and lift the clips that secure it. These are easy to break so take your time and work slowly.

After replacing the battery, reassemble the fob and test it to ensure that everything is working as it should. If it isn't working after pressing the button multiple times, check that the contacts are clean. It is also possible to test it using another key fob to determine whether the issue is specific to that particular key. If not, there may be another reason that caused the key fob not to function. For instance, it could be that the button is worn out. This could cause the button to work a few times and not all the time.

Interference

The key fob is powered by a tiny transmitter that sends out a short-range signal to a device in your car. Its primary function is to permit your vehicle to recognize the key fob, unlock its doors as you approach it, and then turn on when you press the ignition button.

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

Other electronic devices that use the same frequency as the fob can interfere with its signal. This includes garage door openers and tire pressure monitoring systems. Even a transmitter in your home could be interfering however it would be difficult for an expert to test.

Your key fob may also need to be reprogrammed. This requires the transmitter in your fob to be identified by the receiver inside your programming mini cooper key and a distinct code is assigned to each pairing. Fobs are typically changed when they're removed or replaced, or when you buy a new one and, in some instances the battery is changed. To reprogram a fob, follow the instructions in the user's manual of your device or visit a dealer for assistance.

Chips that aren't working

Modern electronic key fobs offer greater convenience and efficiency than manual mini keys. However, they also are more prone to damage. One of the most common issues is a defective chip that stops the fob from functioning properly. This is usually a straightforward fix.

If your fob is constantly not turning on your car, it's a sign that the chip is malfunctioning. It is typically feasible to fix the issue by replacing the battery. This is a cheap and simple solution which can be found at any hardware store or large retailer. To avoid any further issues, make sure you purchase the right battery with your car model.

The fob shouldn't be exposed to water or soapy residue. Water can cause corrosion, which can interfere with the circuit board. If this is the situation, you'll need to clean the board with isopropyl or electronic cleaner prior to installing an entirely new mini key battery.

After the battery has been replaced, it's an excellent idea to test the function of the fob before driving the vehicle. Check the voltage of the new battery using the help of a voltmeter to confirm that it is secure. If not then it may be necessary to replace mini key the entire chip inside the remote. A trained technician from a dealership will help you determine the best solution for your vehicle.
