Mini Replacement Key
It may be that your key fob needs an upgrade to its battery. It may also need to be programmed to work with your vehicle.
This service is usually offered at your local dealership. You can also call a locksmith in your area. They will utilize the VIN number of your vehicle to create an entirely new key.
Battery
The battery in your key fob may run out and cease to function over time. It is easy to replace it at home. Just pry open your fob, pull out the old battery and put in a brand new one. You'll have 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 necessary when placing your order.
Programming
The key that came with your Mini Cooper has a chip that communicates with the car to open the doors and turn on the engine. This is the reason it's essential to have a backup key, whether you require it as a spare or in the event you lose yours. You can get an ordinary car key at a local hardware store. However, you'll require a locksmith program that works with your vehicle.
The process for coding is time-consuming and complicated. The Key Lab needs to be removed from the car and the key data extracted by soldering. The new key will then need to be programmed to your vehicle by a dealer who is authorized or a professional BMW/MINI coder. A majority of locksmiths won't take on the task due to this. If you're able, consider a local independent BMW/MINI coder instead. They will utilize an ID44 chip programmer to connect to the car's BC1 module and read the 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 which may appear random, but they have specific meanings. They are designed to protect cars against fraud and theft.
The three initial characters of a VIN code identify the location and manufacturer of the vehicle. These codes are called the World Manufacturer Identifier (WMI). The characters four through eight provide additional details about the car including its model and the features. The ninth character is the security number that verifies that the VIN is valid. The last character is the year the vehicle was produced.
The VIN number is found in numerous places on your car. The VIN number is typically printed on an adhesive sticker that is visible when you look at the dashboard or windscreen. It can also be seen on the driver-side door jamb when you open the door and examine the inside.
If you're thinking of purchasing an older vehicle, make sure you verify the VIN number before signing the contract. A VIN decoder will help you to comprehend the VIN to ensure that you don't purchase a stolen vehicle or one with damaged. VINs are standardised since 1981. However, pre-1981 vehicles used a different format, which could be difficult for you to understand.
Lockout Service
As opposed to traditional car keys, modern keys come with a transponder chip which can disable the vehicle's standard immobiliser system. The chips are incorporated into the key and transmit an indication to the vehicle's CAS that starts the engine. The benefit of this feature is that it helps to stop thieves from using stolen keys to start your vehicle.
