Changing the Battery in Your Mini Key Fob
The key fob is a convenient way to lock and unlock your car from an extended distance. It also allows you to activate your car's panic button which will deter burglaries.
If your device stops working It can be fixed by following a few steps. Make sure the battery is new. Remove the battery from the ignition, and then press the lock button swiftly three times.
Battery
The easiest way to fix the battery on your key fob is to replace it. The fob uses a small coin-shaped 3V battery (CR2032 or CR2025) that is usually accessible in general stores as well as home improvement shops and a few auto parts stores. Be sure to use a brand new battery -- old batteries are often not good for anything and can damage the circuit board.
You'll need to start by removing the fob. It might be a bit tight but with the help of a flat screwdriver you should be able to separate the two halves. After that, slide the screwdriver into the seam on all sides of the fob to raise a couple clips that hold it in place. They can easily break, so be careful and work slowly.
After replacing the battery take the fob apart and check to see if everything is working according to plan. If it's not working you can try pressing the button several times and ensuring whether the contacts are clean. You can also test it with a spare fob to determine if the issue is not specific to the key. If it is not, there could be a different reason for the key fob not to work. It could be a worn-out button, as an example. This would cause the button to operate occasionally, not every time.
Interference
The key fob has tiny transmitters to transmit an audio signal that is short-range to a receiver inside your vehicle. 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, interference can interfere with the communication. For instance, if you are using your second-generation Apple Pencil charged while you're holding the fob, it could stop you from unlocking your car (via iGeneration).
Other electronic devices that utilize the same frequency as the fob might also interfere with its signal. Garage door openers or tire-pressure monitoring devices can also be affected. It is even possible that an RF transmitter in your home may be interfering with the fob's signal although this would be difficult to identify without an examination by a professional.
It's possible that your fob just needs to be modified. The transmitter inside the fob you have purchased must be recognized by the Mini's receiver. A unique code is used for each pairing. Fobs must be reprogrammed when they are removed from the system or replaced, after purchasing a new one or in some cases, when the battery is replaced. Follow the directions in your owner’s manual to reprogram a key fob or seek assistance from a dealer.
Chips with a problem
Modern electronic key fobs provide convenience and performance over traditional manual keys, however they can also be more susceptible to damage. One of the most frequent issues is a malfunctioning chip that stops your device from functioning properly. Fortunately, this is often an simple fix.
If your car key fob fails to start up, it could be a sign of a damaged chip. The issue can be resolved by replacing the battery, which is inexpensive and easy to find at any hardware store or big box retailer. To avoid future problems ensure that you purchase an appropriate battery with your car model.
It is also crucial to make sure that the fob isn't exposed to soapy residue. Water can cause corrosion and affect the circuitry. If this is the case, you'll have to wash it with isopropyl alcohol or an electronic cleaner before putting in an entirely new battery.
After the battery has been replaced, it's a good idea to test the functionality of the fob before driving the car. Test the voltage of the new battery using an voltmeter to make sure it's secure. If not, you may have to replace the entire remote chip. A trained technician from a dealership will assist you in determining the most suitable solution for your vehicle.

However, reprogramming the key fob might be the solution and it's easy to do.
First, check that the battery in the key fob is good and hasn't been replaced. Once a new battery is installed, it is not able to be reprogrammed, and it will need to be replaced.
