1. Use a small screwdriver to pry open the back of the key fob.
2. Remove the old battery and insert the new battery.

5. Test the key fob to make sure that it is working properly.
Locating the Key Fob Battery
The key fob battery in a BMW vehicle is crucial for operating the car’s remote functions. If you experience issues with your BMW key fob, such as a decreased signal range or intermittent button functionality, it’s likely time to replace the battery. The process of locating the key fob battery varies depending on the specific model and year of your BMW. However, there are some general steps you can follow to find the battery compartment:
Key Fob with Removable Mechanical Key
-
Locate the mechanical key release button or lever. This is typically found on the side of the key fob and may require a small amount of pressure to activate.
-
Press or slide the button/lever to detach the mechanical key from the fob.
-
Flip the key fob over. You should now see a small rectangular panel on the back, held in place by screws or clips.
-
Unscrew the screws or release the clips to remove the panel.
-
Identify the battery. The battery will be a small, round lithium coin cell, typically a CR2032 or CR2025.
Key Fob without Removable Mechanical Key
-
Check under the rubber cover. Some key fobs have a small rubber cover on the back that can be pried open to reveal the battery.
-
Look for a small notch or opening. If there is no rubber cover, inspect the key fob for a small notch or opening. Use a small screwdriver or other tool to gently pry it open.
-
Locate the battery. Once the cover is removed, you should see the battery, typically a CR2032 or CR2025.
