You can repair your device by following few easy steps. Make sure that the battery is brand new. Remove the battery from the ignition, then press the lock button quickly three times.

Battery

The simplest way to fix the battery on your key fob is to replace it. The fob uses the small coin-shaped battery (CR2032, 2025), which is easily found in most general stores and home improvement stores and auto parts stores. Make sure you get the latest battery- old batteries are often not good for anything and can damage the circuit board.

You'll want to start by removing the fob. You may need to use a flat screwdriver split the two halves. Then, fit the screwdriver in the edges of the fob to lift a couple of clips that hold it. These can be easily damaged so be cautious and take your time.

After replacing the battery, reassemble the fob and test it to see if everything is functioning as it should. If it's not working try pressing the button several times before confirming whether the contacts are clear. It is also possible to test it with another key fob to determine whether the issue is specific to a specific key. If not the case, there could be another reason why the key fob isn't functioning. It could be a worn-out button, as an example. This could cause the button to work a few times and not all the time.

Interference

The key fob uses a small transmitter to send a short-range radio signal to a receiver inside your car. Its goal is to enable your car to recognize the fob, and open its doors when you approach it and also start when you hit the ignition button inside.

The problem is, interference can occasionally interfere with the transmission. If you charge your second-generation Apple Pencil while holding the fob (via iGeneration) it could block you from unlocking your vehicle.

Other electronic devices that operate on the same frequency as the fob can interfere with the signal. Garage door openers and tire-pressure monitoring devices can also be affected. It is also possible that an RF transmitter inside your home might be interfering with the fob's signal, but this would be difficult to identify without a professional test.

It's also possible that your key fob is simply changed in its programming. This process requires the transmitter in your fob to be identified by the receiver inside your mini key fobs, and a unique code is assigned to each pairing. Fobs have to be reprogrammed when they are removed from the system or replaced, either after you purchase a new one and, in some instances, when the battery is replaced. To reprogram a fob follow the steps in your owner's manual or ask a dealer for assistance.

Chips that aren't working

Modern electronic key fobs provide convenience and functionality over traditional manual locked keys in mini cooper, however they can also be more susceptible to damage. A malfunctioning chip is among the most frequent problems that can stop your key fob from operating correctly. Fortunately, it's usually an easy fix.

If your car key fob fails to start up it could be an indication of a defective chip. It is often possible to fix the problem by simply replacing the battery. This is an inexpensive and simple solution that is available at any hardware store or large retailer. Make sure you purchase the right replacement battery compatible with your specific model of car to avoid further problems.

The fob should also not be exposed to water, or soapy residue. Water can cause corrosion, which could cause issues with the circuit board. If this is the case, you'll need to clean the circuit board with isopropyl alcohol or an electronic cleaner prior to putting in a new battery.

It is a good practice to test the operation of the fob prior to operating the vehicle. Test the voltage of the new battery using the help of a voltmeter to confirm that it is secure. If not then it may be required to replace the entire chip in the remote. A trained technician from a dealership can help you determine the best solution for your car.
