Changing the Battery in Your Mini Key Fob
The key fob is an easy option to lock and unlock your vehicle from some distance. It can also activate the panic button on your car, which can scare off break-ins.
If your device stops working the device can be repaired by following a few simple steps. First, make sure that the battery is brand new. Remove the battery from the ignition and then press the lock button rapidly three times.
Battery
The most straightforward way to repair the battery on your key fob is to replace it. The fob uses a small coin-shaped 3V battery (CR2032 or CR2025) that is generally available in general stores or home improvement stores and a few auto parts stores. Make sure you use a new battery -older batteries are typically not good for anything and can cause damage to the circuit board.
Start by removing the fob. You may need to make use of 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 secure it. These are easily broken therefore, proceed slowly and with care.
Reassemble the fob after replacing the battery and check to see if it works as it should. If it's still not working try pressing the button a few times before confirming whether the contacts are clean. You could also try it with a spare key fob to determine if the issue is specific to your key. If not the case, there could be another reason for why the key fob isn't functioning. It could be due to a worn button, for instance. This could cause the button to function occasionally, not every time.
Interference
The key fob is powered by a tiny transmitter that transmits signals of a short range 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 and also start when you push the ignition button within.
Interference can occasionally interfere with communication. If mini car key charge your second-generation Apple Pencil while holding the fob (via iGeneration), it could prevent you from unlocking your vehicle.
Other electronic devices that use the same frequency as the fob can interfere with its signal. Garage door openers or tire pressure monitoring devices can be affected. It's even possible that an RF transmitter in your home might interfere with the fob's signal though this would be difficult to determine without an expert test.
Your key fob might require reprogramming. This process will require the transmitter in your fob to be identified by the receiver in your Mini, and a unique code is used for each pairing. Fobs typically need to be programmed after being removed or replaced, or when you buy a new one or, in rare cases it's when a battery has been changed. To reprogram a fob follow the steps in your owner's manual or contact a dealer for assistance.
Chip that is not working
Modern electronic key fobs offer more convenience and functionality than manual keys. However they are also more susceptible to damage. A faulty chip is among the most frequent problems that can prevent the key fob from working correctly. Fortunately, this is often an simple fix.
If your fob keeps failing to turn on your car, it's an indication that the chip is damaged. It is typically possible to fix the problem by simply replacing the battery. This is an inexpensive and simple fix which can be found at any hardware store or large retailer. Make sure you buy the right replacement battery compatible with your particular model of car to avoid further problems.
The fob should not be exposed to water, or soapy residue. Water can cause corrosion and disrupt the circuitry. If this is the situation it is necessary to clean the board with isopropyl or electronic cleaner prior to installing a new battery.
After the old battery has been replaced, it's recommended to test the fob's function before driving the vehicle. With a voltmeter, test the voltage of the replacement battery to see whether it's at a safe level. If not then it may be required to replace the entire chip inside the remote. A trained technician from a dealership will help you determine the best solution for your vehicle.
