BMW key fobs use different types of batteries depending on the model and year. The most common types are:

How to Replace a BMW Key Fob Battery: A Step-by-Step Guide

Replacing the battery in most BMW key fobs is a straightforward process:

1. Locate the battery compartment: Most BMW key fobs have a small release button or sliding mechanism on the back that opens the battery compartment.
2. Open the key fob: Use a small flat-head screwdriver or a coin to gently pry open the key fob along the designated seam.
3. Remove the old battery: Carefully remove the old battery from its slot. Note the orientation of the positive (+) and negative (-) sides.
4. Insert the new battery: Place the new battery in the slot, ensuring the positive (+) and negative (-) sides match the orientation of the old battery.
5. Close the key fob: Align the two halves of the key fob and press them together until they snap shut.
6. Test the key fob: Press a button on the key fob to ensure it’s working correctly.

Note: If your BMW key fob has a touchscreen display, you might need to follow a slightly different procedure.
