Understanding Your BMW Key Fob
Before you begin the battery replacement process, it’s helpful to understand the components of your BMW key fob. The key fob for the 2011 BMW 550i typically uses a CR2032 battery, a common type of lithium coin battery found at most electronic and automotive stores.

- A soft cloth or microfiber towel (optional)
Step-by-Step Battery Replacement Guide
Follow these simple steps to replace your BMW key fob battery:
- Locate the Battery Compartment: The battery compartment is typically located on the back of the key fob. You’ll notice a small slot or indentation.
- Open the Battery Compartment: Carefully insert the flathead screwdriver into the slot and gently pry open the battery compartment cover. Avoid using excessive force to prevent any damage to the key fob.
- Remove the Old Battery: Once the compartment is open, gently remove the old CR2032 battery. Note the orientation of the positive (+) and negative (-) sides of the battery for correct placement of the new one.
- Insert the New Battery: Align the positive (+) side of the new CR2032 battery with the corresponding marking inside the battery compartment. Carefully press the battery into place.
- Close the Battery Compartment: Align the cover and press it firmly until it snaps back into place.
Testing Your New Key Fob Battery
After replacing the battery, test all key fob functions, including locking/unlocking the doors, opening the trunk, and starting the engine, to ensure everything is working correctly.
Troubleshooting Tips
If your key fob still isn’t working properly after replacing the battery, here are a few things you can try:
- Check the Battery Orientation: Make sure the new battery is installed with the positive (+) side facing the correct direction.
- Clean the Battery Contacts: Over time, the battery contacts inside the key fob can become dirty or corroded. Use a soft cloth or cotton swab dipped in rubbing alcohol to gently clean the contacts.
- Reprogram the Key Fob: In some cases, you may need to reprogram your key fob to your BMW after replacing the battery. You can find instructions on how to do this in your owner’s manual or by searching online for “2011 BMW key fob programming.”
