Changing the Battery in Your Mini Key Fob
The key fob can be a convenient option to lock and unlock your car from a distance. It also allows you to activate your car's panic button which can prevent burglaries.
If your fob stops working It can be fixed with a few easy steps. Make sure the battery is brand new. Then, remove it from the ignition by pressing the lock button three times rapidly.
Battery
Switching the battery on your key fob is one of the easiest fixes. The fob uses the small coin-shaped battery (CR2032, and CR2025), which is easily found in most general stores as well as home improvement stores and auto parts stores. Use a brand new battery. Old batteries can cause damage to the circuit boards and become less useful.
You'll want to start by opening the fob. You may need to use a flat screwdriver separate the halves. Install the screwdriver into the seams on both sides of the fob, and lift the clips which hold it in place. These can be easily damaged so be cautious and work slowly.
Reassemble TheKeyLab after replacing the battery and test to determine if it works as it should. If it isn't working after pressing the button several times, make sure that the contacts are clean. You can also try it with a spare key fob in order to determine whether the issue is limited to a particular key. If not, there may be a different reason for the key fob to not work. It could be due to a worn-out button, as an example. This would only cause the button to work a few times but not continuously.
Interference
The key fob has a tiny transmitter to send a radio signal of a short range to a device in your vehicle. Its function is to permit your car to recognize the fob and open its doors when you approach it and also start when you press the ignition button inside.
Interference may sometimes hinder communication. For instance, if have your second-generation Apple Pencil charged while you're holding the fob, it may prevent you from unlocking the car (via iGeneration).
Other electronic devices operating on the same frequency can also interfere with the fob's signal. Garage door openers or tire pressure monitoring devices can be affected. It's possible that an RF transmitter in your home might interfere with the fob's signals, although this would be difficult to diagnose without an examination by a professional.
It's also possible that the key fob just needs to be modified. This requires the transmitter in your fob to become recognized by the receiver in your Mini and a unique code is used for each pairing. Fobs are typically reset when they are disconnected or replaced, when you purchase a replacement and, in some instances when the battery is changed. To reprogram a fob, follow the steps in your owner's manual or go to a dealer to seek assistance.
Faulty chip
Modern electronic key fobs offer more convenience and function than traditional manual keys. However they also are more prone to damage. One of the most frequent issues is a malfunctioning chip that can stop the fob from functioning properly. Luckily, this is usually an easy fix.
If your fob keeps not turning on your car, it's a sign that the chip is malfunctioning. The issue is usually solved by replacing the battery, that is inexpensive and simple to find at the hardware store or a big-box retailer. Make sure you purchase the correct battery compatible with your specific model of car to avoid further issues.
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 will have to wash it with isopropyl alcohol or electronic cleaner prior to installing the new battery.
Once the old battery is replaced, it's an excellent idea to test the functionality of the fob before driving the vehicle. Using a voltmeter, check the voltage of the new battery to determine whether it is at a safe level. If not, it may be required to replace the entire chip in the remote. A trained dealer technician can assist you in determining the best solution for you vehicle.
