Battery

The most straightforward way to repair the battery in your key fob is to replace it. The fob uses a small coin-shaped 3V battery (CR2032 or CR2025) which is typically easy to find in general stores or home improvement stores and some auto parts stores. You should use a new battery. Old batteries can damage the circuit boards and become less useful.

You'll want to start by prying the fob open. It might be a bit tight but with the aid of a flat screwdriver you should be able separate the halves. Then, you can insert the screwdriver into the edges of the fob to lift a couple of clips holding it in place. These can be easily damaged so be cautious and work slowly.

After replacing the battery replace the fob, then test it to ensure that everything is functioning exactly as it should. If it does not work after pressing the button a few times, ensure that the contacts are clean. You can also test it with a spare key fob to determine if the issue is confined to your key. If not, there may be another reason why the key fob isn't working. It could be due to a worn-out button, for instance. This will only cause the button to work a few times but not constantly.

Interference


The key fob has a tiny transmitter to send an audio signal that is short-range to a receiver in your vehicle. Its function is to permit your car to recognize the fob and then open its doors when you approach it and to start when you hit the ignition button inside.

Interference can interfere with communication. For instance, if have your second-generation Apple Pencil charged while you're holding the fob, it might stop you from unlocking your car (via iGeneration).

Other electronic devices operating on the same frequency could also interfere with the fob's signal. This could include garage door openers and tire pressure monitoring systems. It is even possible that an RF receiver inside your home may interfere with the fob's signal but this would be difficult to diagnose without an examination by a professional.

It's possible that your key fob simply needs to be changed in its programming. This process requires the transmitter on the fob to be recognized by the receiver in your Mini, and a unique code is used for each pairing. The fob needs to be programmed after they have been disconnected or replaced, if you buy a new one and in certain cases when the battery is replaced. To reprogram a fob, follow the instructions in your owner's manual or visit a dealer for assistance.

Chips that aren't working

Modern electronic key fobs provide convenience and performance over traditional manual keys, but they are also more vulnerable to damage. One of the most frequent problems is a faulty chip that can stop your fob from functioning correctly. It is usually a simple fix.

If your fob is always not turning on your car, it is a sign that the chip is damaged. It is usually possible to fix the issue by simply replacing the battery. This is a cost-effective and easy solution which can be found at any hardware store or retailer. Make sure to purchase the right replacement battery compatible with the model of your car to avoid further problems.

The fob should not be exposed to water, or soapy residue. The presence of water can cause corrosion, which can interfere with the circuit board. If this is the case, you will need to clean the circuit board using isopropyl alcohol, or an electronic cleaner prior to installing a new battery.

It is a good practice to test the functioning of the fob before driving the vehicle. Utilizing a voltmeter, examine the voltage of the new battery to see whether it is at an acceptable level. If not, you might need to replace the whole remote chip. A trained technician from a dealership will help you determine the best solution for your car.
