Remove the old battery and replace it with a new one. The Mercedes-Benz B200CDI is a compact car with body dimensions of 4423mm in length, 1796mm in width, and 1555mm in height, with a wheelbase of 2729mm.

I recently helped a friend replace the battery in the key fob of a new Mercedes-Benz B200 CDI, and it was quite straightforward. First, locate the small seam on the key, usually on the side or back, then gently pry open the casing using a small flathead screwdriver or a thin card—be careful not to use too much force to avoid damaging the exterior. Once opened, you'll find a coin cell battery inside, typically a CR2032. When removing the old battery, note its orientation, and insert the new one the same way, ensuring the positive and negative terminals align correctly. Then, simply snap the casing back together and press gently to secure it. After replacement, test the key's lock/unlock and ignition functions to ensure they work properly. For daily use, avoid exposing the key to high temperatures, such as under the windshield, to extend the battery life to one or two years.
I've repaired many car keys before, and the key to replacing the battery for the new Mercedes-Benz B200CDI is safety first. Don't be careless when preparing tools; small tools like eyeglass screwdrivers will do, and avoid using sharp objects to prevent scratching the plastic casing. When operating, first turn off the car and keep the key clean, as dust can get inside and affect the circuitry. After opening the casing, slowly remove the old battery without disturbing the internal contacts. Make sure the new battery is the correct specification, CR2032, and don't skimp by using cheap, low-quality brands. Test the remote function several times after replacement to ensure responsive operation. Finally, it's recommended to check the key's battery level every six months. If you encounter any trouble, seek professional help promptly instead of forcing it—trying to fix it yourself and causing more damage can lead to more trouble.
