Experiencing the frustration of your 2011 BMW 328i xDrive refusing to start? Before you panic and call a tow truck, there’s a simple fix you can try: replacing the key fob battery. Often, a dead key fob battery is the culprit behind starting issues, leaving you stranded and unsure of what to do. This article will guide you through the process of replacing your key fob battery and get you back on the road in no time.
Why Your Key Fob Battery Matters
Your key fob isn’t just a fancy remote to lock and unlock your BMW. It plays a crucial role in starting your car. Inside, a tiny battery powers the immobilizer chip, which communicates with your car’s ignition system. When this battery dies, the communication breaks down, preventing your car from starting.
Here are some telltale signs that your key fob battery is on its last legs:
- Decreased Range: You need to be much closer to your car for the lock/unlock buttons to work.
- Intermittent Functionality: The key fob works sometimes, but not others.
- Warning Messages: Your dashboard might display warnings like “Key Fob Battery Low.”

- Access the Battery: Once the fob is open, you’ll see the battery nestled inside. Note the battery’s orientation (+/-).
- Replace the Battery: Carefully remove the old battery and insert the new one, ensuring the positive (+) side faces up, matching the orientation of the old battery.
- Reassemble the Key Fob: Align the two halves of the key fob and press them firmly together until you hear a click, indicating it’s securely closed.
