Battery
The most simple way to fix your key fob's battery is to replace it. The device uses a small coin-shaped 3V battery (CR2032 or CR2025) that is generally easily found in general stores or home improvement stores and some auto parts stores. You should use a new battery. Old batteries can harm the circuit boards and are no longer useful.
It is recommended to begin by prying the fob open. You may have to use a flat screwdriver break the two halves. Then, you can insert the screwdriver in the seam on both sides of the fob to lift the clips that hold it. These can be easily damaged, so be careful and take your time.
After replacing the battery take the fob apart and check to see if everything is functioning exactly as it should. If it doesn't function after pressing the button several times, make sure that the contacts are clean. You could also try it using another key fob to determine whether the issue is specific to a particular key. If it isn't then there could be a different reason for why your key fob isn't functioning. It could be due to a worn button, for instance. This could cause the button to function at times, not always.
Interference
The key fob is powered by a small transmitter that sends out the signal in a short distance to a device in your car. Its function is to allow your vehicle to recognize the key fob and open its doors when you come close to it, and then start when you push the ignition button.
The problem is that interference can sometimes interfere with the transmission. If you charge your second-generation Apple Pencil while holding the fob (via iGeneration), it could prevent you from unlocking the vehicle.
Other electronic devices that utilize the same frequency as the fob might also interfere with its signal. This could include garage door openers as well as tire-pressure monitoring systems. Even a transmitter inside your home could be causing interference with the tire pressure, but this isn't easy for a professional to test.
It's possible that your key fob is simply reset. This process requires the transmitter in the fob to be recognized by the receiver inside your Mini and a unique code is assigned to each pairing. The fobs will typically need to be reprogrammed when they're disconnected or replaced, when you buy a new one and, in some instances the battery is changed. Follow the steps in your owner's manual to reprogram your key fob or seek assistance from a dealer.
Faulty chip
Modern electronic key fobs offer more convenience and functionality than manual keys. However they also are more prone to damage. A damaged chip is among the most common issues that could stop your key fob from working correctly. Fortunately, this is often an easy fix.
If your car key fob doesn't seem to turn on, it could be the result of a damaged chip. It is often feasible to fix the issue by simply replacing the battery. This is a cheap and simple solution that can be purchased at any hardware store or retailer. Make sure you purchase a replacement battery that is compatible with your model of car to avoid recurring issues.
The fob should also not be exposed to water, or soapy residue. Water can cause corrosion, which can interfere with the circuit board. If this is the case you'll need to wash the board with isopropyl or an electronic cleaner prior to installing an entirely new battery.
Once the old battery is replaced, it is recommended to test the function of the fob before driving the car. Utilizing a voltmeter, examine the voltage of the new battery to see whether it's at an acceptable level. If not, it might be necessary to replace the entire chip inside the remote. A trained dealer technician can assist in determining the best solution for you vehicle.
