Changing the Battery in Your Mini Key Fob

The key fob allows you to lock and unlock your vehicle from an extended distance. It can also activate the panic button on your vehicle that can stop burglaries.

You can repair your fob by following a few steps. First, ensure that the battery is brand new. Remove the battery from the ignition and then press the lock button swiftly three times.

Battery

The easiest way to fix the battery in your key fob is to replace it. The fob has a tiny coin-shaped 3V battery (CR2032 or CR2025) that is accessible in general stores, home improvement shops, as well as some auto parts stores. Make sure you use the latest batteryolder batteries are typically not good for anything and can damage the circuit board.

Begin by opening the fob. It might be tight, but with the help of a flat screwdriver, you should be able to separate the two halves. Then, insert the screwdriver in the seam on both sides of the fob to lift the clips to secure it. These are easily broken, so be careful and slow.

Reassemble the fob after replacing the battery, and test to determine if it functions as it should. If it doesn't work try pressing the button a few times and checking whether the contacts are clean. It is also possible to test it with a spare key fob in order to determine if the issue is isolated to a specific key. If it is not, there could be another reason for the key fob not to function. It could be a worn-out button, as an example. This will only trigger the button periodically, not continuously.

Interference

The key fob is powered by a tiny transmitter that sends out the signal in a short distance to a receiver in your car. Its function is to permit your car to recognize the fob and unlock its doors when you approach and start when you press the ignition button in.

The problem is, interference can interfere with that communication. 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 operating on the same frequency can also interfere with the fob's signal. Garage door openers or tire pressure monitoring devices could be affected. Even a transmitter at your home could be interfering with the tire pressure, but this is not easy for professionals to test.

The key fob might need to be reprogrammed. The transmitter in your key fob has to be recognized by Mini's receiver. A unique code is then generated for each pairing. Fobs are typically reprogrammed when they're removed or replaced, or when you purchase a new one or, in certain cases when the battery is changed. To reprogram a fob follow the steps in the user's manual of your device or visit a dealer for assistance.

It is also crucial to ensure that the fob is not exposed to soapy residue. The presence of water can cause corrosion, which can cause interference with the circuit board. If this is the case, you'll have to wash it by using isopropyl or electronic cleaner prior to installing the new battery.

After the battery has been replaced, it is recommended to test the fob's function before driving the car. Check the voltage of the new battery with a voltmeter to ensure it is safe.
