Changing the Battery in Your mini cooper spare key Key Fob
The key fob is an easy way to lock and unlock your vehicle from a distance. It can also activate your car's panic button that can stop burglaries.
You can repair your device by following few simple steps. Ensure that the battery is new. Then, try removing it from the ignition and pressing the button to lock three times quickly.
Battery
The easiest way to fix your key fob's battery is to replace it. The fob uses a small coin-shaped 3V battery (CR2032 or CR2025) that is usually accessible in general stores, home improvement shops, and some auto parts stores. Use a brand new battery. Old batteries can cause damage to the circuit boards and are no longer useful.
Start by opening the fob. You may need to make use of a flat screwdriver to break the two halves. Then, fit the screwdriver in the edges of the fob, and then lift up a couple of clips that hold it. They can easily break, so be careful 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 doesn't function after pressing the button multiple times, make sure that the contacts are clean. It is also possible to test it using an additional key fob to determine whether the issue is limited to a specific key. If it is not, there could be another reason behind the key fob to not work. It could be a worn-out button, as an example. This would trigger the button occasionally, not every time.
Interference
The key fob has a tiny transmitter to send the short-range radio signal to a device in your car. Its goal is to enable your vehicle to recognize the key fob, unlock its doors when you are near it, and then start when you press the ignition button.
Interference can occasionally interfere with communication. If you charge your second-generation Apple Pencil while holding the fob (via iGeneration) it may prevent you from unlocking your vehicle.
Other electronic devices that use the same frequency as the fob may also interfere with its signal. Garage door openers or tire pressure monitoring devices could be affected. A transmitter in your home could be interfering however this is not easy for a professional to test.
Your key fob may also require reprogramming. This procedure requires the transmitter on the fob to be recognized by the receiver in your Mini and a specific code is assigned to each pairing. Fobs typically need to be changed when they're disconnected or replaced, when you buy a new one, and in some cases the battery is changed. To reprogram a fob, follow the instructions in the owner's guideline or visit a dealer for assistance.
Chips that aren't working
Modern electronic key fobs offer the convenience and functionality of traditional manual keys, but they are also more vulnerable to damage. One of the most common issues is a defective chip that prevents your fob from functioning correctly. Fortunately, it's usually an easy fix.
If your fob is always not turning on your car, this could be an indication that the chip has become defective. The issue can usually be fixed by replacing the battery, which is inexpensive and easy to find at any hardware store or big box retailer. To avoid further problems ensure you buy the correct battery with your car model.
The fob shouldn't be 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 wash it with isopropyl alcohol or an electronic cleaner prior to putting in the new battery.
It is a good practice to test the operation of the fob prior driving the vehicle. Check the voltage of the new battery using a voltmeter to ensure it's safe. If not, you may need to replace the entire remote chip. A trained technician from a dealership will help you choose the best solution for your vehicle.
