How to Replace the Battery in Your 2010 BMW 528i Key Fob
Replacing the key fob battery is a task you can easily tackle at home. Here’s a step-by-step guide to walk you through the process:
- Gather Your Supplies: You’ll need a fresh CR2032 battery (easily found at most supermarkets, electronics stores, or online), a small flat-head screwdriver, and your 2010 BMW 528i key fob.
- Open the Key Fob: Locate the small release button on the back of your key fob. Press this button while gently separating the two halves of the key fob.
- Access the Battery: Inside, you’ll see the CR2032 battery housed within the key fob. Carefully remove the old battery by prying it out with your flat-head screwdriver.

- Reassemble the Key Fob: Align the two halves of the key fob and press them together firmly until they snap back into place.
- Test the Key Fob: Try locking and unlocking your car doors and starting the engine to confirm the new battery is functioning correctly.
