Replacing the 2012 BMW 750 Key Fob Battery: A Step-by-Step Guide
You’ll need a few things before you begin:
- A new CR2032 battery (easily found at most convenience stores and online retailers)
- A small flat-head screwdriver

-
Locate the release button: Examine your key fob. You’ll find a small, rectangular release button, typically on the back or side.
-
Release the key blade: Press the release button and gently slide out the metal key blade from the fob.
-
Open the fob casing: With the key blade removed, use the flat-head screwdriver to carefully pry open the fob casing. There’s usually a small notch that serves as a leverage point.
-
Replace the battery: Inside, you’ll find the CR2032 battery. Carefully remove it and replace it with the new one, ensuring the positive (+) side faces up.
-
Reassemble the fob: Align the two halves of the fob casing and press them together until you hear a click, indicating they’re securely closed.
-
Reinsert the key blade: Slide the metal key blade back into its slot on the fob until it locks into place.
-
Test the key fob: Ensure all buttons function correctly by locking and unlocking your car doors and testing other features.
Tips for a Smooth Battery Replacement:
-
Handle the battery with care: Avoid touching the flat surfaces of the new battery, as this can reduce its lifespan.
-
Note the battery orientation: Ensure the new battery is inserted with the positive (+) side facing the same direction as the old one.
-
Be gentle when prying: Apply minimal pressure when opening the fob casing to avoid damaging the plastic.
-
Don’t overtighten: When reassembling, avoid excessive force, as this could damage the fob.
