The Most Popular Mini Cooper Key Replacement Is Gurus. Three Things
Changing the Battery in Your Mini Key Fob
The key fob is a convenient method to lock and unlock your car from the distance. It also allows you to activate the panic button on your vehicle that can deter thieves.
If your device ceases to function It can be fixed by following a few simple steps. Make sure the battery is new. Remove the battery from the ignition, and then press the lock button rapidly three times.
Battery
Switching the battery on your key fob is one of the easiest solutions. The key fob uses a tiny coin-shaped battery (CR2032 or the CR2025) It can be found in most general stores or home improvement stores and auto parts stores. Use a new battery. Old batteries can harm the circuit boards and cease to be useful.
You'll want to start by opening the fob. You may need to use a flat screwdriver to separate the halves. Then, fit the screwdriver into the seams on both sides of the fob, and then lift up a couple of clips to secure it. These can be easily damaged, so be careful and work slowly.
After replacing the battery take the fob apart and test it to see if everything is working just as it should. If it doesn't function after pressing the button several times, make sure that 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 not the case, there could be another reason for why the key fob isn't functioning. For example it could be because the button is worn out. This would only cause the button to work at times, not always.
Interference
The key fob has a tiny transmitter to send a short-range radio signal to a receiver inside your car. Its goal is to enable 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. If you charge your second-generation Apple Pencil while holding the fob (via iGeneration) it could stop you from unlocking your vehicle.
Other electronic devices that operate on the same frequency as the fob might interfere with its signal. This could include garage door openers, as well as tire pressure monitoring systems. Even a transmitter inside your home could be causing interference, but this would be difficult for professionals to test.
It's also possible that the key fob just needs to be reset. This will require the transmitter in your fob to be identified by the receiver in your Mini, and a unique code is assigned to each pairing. The fobs will typically need to be programmed after being removed or replaced, or when you purchase a replacement or, in certain cases when the battery is changed. Follow the instructions in your owner’s manual to change the programming of a key fob. You can also ask a dealer for help.

Chip that is not working
Modern electronic key fobs offer convenience and functionality over traditional manual keys, but they can also be more vulnerable to damage. One of the most common issues is a damaged chip that prevents your device from functioning properly. Luckily, this is usually an easy fix.
If your fob is always not turning on your car, this is an indication that the chip has become defective. It is typically feasible to fix the issue by simply replacing the battery. This is a low-cost and simple solution that is available at any hardware store or large retailer. To avoid any further issues, make sure you purchase the correct battery with the vehicle model you are using.
The fob shouldn't be exposed to water, or soapy residue. Water can cause corrosion and affect the circuitry. If this is the case you'll have to clean the board with isopropyl, or an electronic cleaner prior to installing an entirely new battery.
It is a good practice to test the operation of the fob before driving the vehicle. Examine the voltage of new battery using an voltmeter to make sure it is safe. If not, it might be required to replace the entire chip in the remote. A qualified dealership technician can assist you in determining the best solution for your car.
