Changing the Battery in Your Mini Key Fob

The key fob is a handy method to lock and unlock your car from some distance. It can also activate your vehicle's panic button which can prevent burglaries.

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

Battery

The most straightforward way to repair your key fob's battery is to replace it. The fob uses the small coin-shaped battery (CR2032, and CR2025) It can be located in the majority of general stores as well as home improvement stores and auto parts stores. Make sure you get an original battery -Old batteries are generally not suitable for any purpose and could damage the circuit board.

The Keylab is recommended to begin by prying the fob open. You may have to use a flat screwdriver to split the two halves. Place the screwdriver through the seams on both sides of the fob and lift the clips that hold it. They are very easily broken So, proceed slowly and with care.

After replacing the battery, reassemble the fob and check to see if everything is functioning exactly as it should. If it isn't working after pressing the button a few times, make sure the contacts are clean. You can also test the fob with a spare to see if the problem is not specific to the key. If it is not, there could be another reason that caused the key fob to not function. For instance it could be because the button is worn out. This will only cause the button to function at times, not always.

Interference

The key fob uses an insignificant transmitter to send the short-range radio signal to a receiver within your car. Its function is to allow your vehicle to recognize the key fob, open its doors as you approach it, and then turn on when you press the ignition button.

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


Other electronic devices that use 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. It is even possible that an RF receiver inside your home could be interfering with the fob's signal although this would be difficult to diagnose without a professional test.

The key fob might require reprogramming. This requires the transmitter in the fob to be recognized by the receiver in your Mini and a distinct code is used for each pairing. Fobs need to be reprogrammed after being disconnected or replaced, after you buy a new one and in certain cases when the battery is replaced. To reprogram a fob follow the directions in your owner's manual or contact a dealer for assistance.

The fob should also not be exposed to water, or soapy residue. Water can cause corrosion and affect the circuitry. If this is the case, you'll require cleaning it by using isopropyl or electronic cleaner prior to putting in an entirely new battery.

Once the old battery is replaced, it is a good idea to test the fob's functionality before driving the vehicle.
