Changing the Battery in Your Mini Key Fob

The key fob is a handy way to lock and unlock your vehicle from an extended distance. It can also activate your car's panic button which will deter burglaries.

If your device ceases to function the device can be repaired by following a few steps. First, check that the battery is brand new. Then, try taking it from the ignition by pressing the button to lock three times quickly.

Battery

The most straightforward way to repair the battery of your key fob is to replace it. The key fob is powered by a tiny coin-shaped 3V battery (CR2032 or CR2025) that is generally easily found in general stores or home improvement stores and even some auto parts stores. Make sure to use an original battery -old batteries are usually not suitable for any purpose and can damage the circuit board.

Begin by opening the fob. You may need to employ a flat screwdriver in order to break the two halves. Place the screwdriver through the seams on both sides of the fob and lift the clips that hold it. They are easily broken so be cautious and take your time.

Reassemble the fob after replacing the battery and check to see if it does what it is supposed to. If it still doesn't work try pressing the button several times and ensuring that the contacts are in good order. You can also test the fob with a spare to see if the problem is specific to your key. If not, then there could be another reason for the key fob not to function. For example it could be because the button is worn out. This would only make the button work occasionally and not all the time.

Interference

The key fob is powered by a tiny transmitter that sends out an extremely short-range signal to a receiver inside your car. Its goal is to enable your car to recognize the fob and unlock its doors when you approach it, as well as start when you press the ignition button inside.

The issue is that interference can interfere with the communication. If you charge your second-generation Apple Pencil while holding the fob (via iGeneration), it could prevent you from unlocking your vehicle.

Other electronic devices that operate on the same frequency as the fob can also interfere with its signal. This can include garage door openers, as well as tire pressure monitoring systems. It's even possible that an RF transmitter within your home may interfere with the fob's signal, however, this is difficult to pinpoint without an examination by a professional.

It's possible that your key fob simply needs to be reset. This process requires the transmitter on your fob to be identified by the receiver in your Mini and a distinct code is used for each pairing. Fobs usually need to be programmed after being disconnected or replaced, when you buy a new one, and in some cases it's when a battery has been changed. Follow the instructions in the owner's manual to reprogram your key fob or consult a dealer.

Chip that is not working

Modern electronic key fobs offer greater convenience and efficiency than manual keys. However they are also more vulnerable to damage. A defective chip is among the most common issues that can stop the key fob from working correctly. Luckily, this is usually an simple fix.

If your fob is always not turning on your car, it is an indication that the chip has become faulty. The issue can usually be resolved by replacing the battery which is cheap and easy to locate at an hardware store or big-box retailer. To avoid any further issues ensure you buy a battery that is compatible with your car model.

It is also essential to make sure that the fob isn't exposed to water or soapy residue. Water will often cause corrosion, which could cause issues with the circuit board. If this is the case it is necessary to clean the board with isopropyl or electronic cleaner prior to installing the new battery.

It is a good idea to test the functioning of the fob prior driving the vehicle. With a voltmeter, test the voltage of the replacement battery to see whether it's at an acceptable level. If not, you could need to replace the whole remote chip. A trained technician from a dealership can assist you in determining the most suitable solution for your vehicle.
