If your key fob isn't working it may be due to a new battery. It could also need to be reprogrammed in order to work with your vehicle.

Usually, you can find this service at your dealer. You can also contact the local locksmith. They will use your car's VIN number to make a replacement key for you.
Battery
The battery inside your key fob might wear out and cease to function over time. It's easy to replace it at home. Simply pry open the fob and take out the old batteries and snap in the new ones. You'll need to put in some effort, but eventually you'll be back on the road. Some key fobs require you to purchase an internal key blade so please add that if you require it when placing your order.
Programming
The key that comes with your mini Cooper is equipped with a specific chip inside which communicates with the car to open the doors and start the engine. This is why it's crucial to have a backup key whether you require it as a spare or in the event you lose yours. You can purchase an ordinary car key at your local hardware store. However, you will require a locksmith to program to make it compatible with your vehicle.
The process of coding is complicated and time-consuming. The CAS module has to be removed from the car, and the key data extracted by soldering. The new key will need to be programmed by a licensed BMW/MINI dealer, or a professional BMW/MINI coder. The majority of locksmiths will not accept the job because of this. If you are able, try an independent, local BMW/MINI coder instead. They will use an ID44 chip programmer to connect to your car's BC1 module and read the existing EWS (immobilizer) code from the old key to program the new one.
VIN Number
Each vehicle has its own unique VIN number. This VIN number is made up of 17 characters. These may appear random, but they have specific meanings. They are designed to protect cars from fraud and theft.
The first three characters of the VIN identify the location where the vehicle was made and the name of the manufacturer. These are known as the World Manufacturer Identifier or WMI codes. The characters 4-8 provide more details about the car such as the model and its features. The ninth character is a security code that verifies the VIN as valid. The last character is the year that the vehicle was manufactured.
You can find the VIN number on a variety of places inside your vehicle. The VIN number is typically printed on a sticker that you can see when you look up at the dashboard or the windscreen. You can also see it on the driver-side door jamb when you open the door and examine the inside.
If you are thinking of buying a used car, make sure to verify the VIN number before signing the contract. A VIN decoder will assist you to comprehend the VIN so that you don't purchase a stolen vehicle or one with damage. VINs are standardized since 1981. However, prior to 1981, vehicles used a different format that could be difficult to understand.
Lockout Service
Modern key fobs are equipped with a transponder that can disable the vehicle's immobiliser. The chips are embedded into the key and send an indication to the vehicle's CAS, which starts the engine. The benefit of this feature is that it will prevent thieves from using a stolen key to start your vehicle.
As a division of BMW, MINI has a reputation for upholding high standards of design and technology. You can exchange the keys on any MINI model, whether old or new. However, this service is usually targeted at drivers with cars that are compatible with key fobs.
It may be that your key-fob needs a new battery. One of the most common signs is the fact that it takes longer than normal to press the lock/unlock button. If this is the situation you should call a locksmith local to repair the battery in your fob. The process will take between 10 to 30 minutes. This is a much faster and cheaper option than replacing the key fob in its entirety. It is also a good service if you've locked yourself out of your vehicle and need help getting back in.
