Open the Key Fob
When it comes to opening your BMW key fob to access the battery, you’ll need to locate the seam along the edge. Use a flathead screwdriver or a coin to gently pry open the fob. Be careful not to use excessive force to avoid damaging the key fob casing.

In some key fob models, there might be a small clip holding the battery in place. Use a tool such as tweezers to carefully unclip it and take out the old battery. Dispose of the old battery properly, following any local recycling guidelines.
Remember, each key fob model may have slight variations in how it opens, so always refer to your specific vehicle’s manual for detailed instructions.
