If you’re driving a 2011 BMW 528i, chances are you love the luxurious feel and powerful performance it offers. But even the most sophisticated vehicles need a little TLC now and then. One common issue you might encounter is a dying key fob battery. Don’t worry, though. Replacing it is a simple task you can handle yourself. This guide will walk you through each step, ensuring you’re back to enjoying your BMW in no time.
Recognizing a Dying Key Fob Battery
Before you start digging for tools, let’s make sure your key fob battery is actually the culprit. Here are a few telltale signs:
- Decreased Range: Is your car only responding to the key fob from a very short distance? This is a classic indicator that the battery is losing power.
- Intermittent Functionality: Does your car unlock sometimes but not others, even when you’re sure you’re pressing the right button? A dying battery could be to blame.
- Warning Messages: Your BMW might be smart enough to display a warning message on your dashboard, alerting you to a low key fob battery.
What You’ll Need for the Replacement
Ready to tackle this DIY project? Great! Here are the tools you’ll need:
- A New Battery: You’ll need a CR2032 3V lithium battery. These are readily available online and at most electronics and auto parts stores.
- A Small Flat-head Screwdriver: This will be your trusty sidekick for prying open the key fob casing.

Now for the main event – the replacement itself. Just follow these simple steps:
- Locate the Release Button: On the back of your key fob, you’ll find a small button. Press it to release the metal key blade.
- Gently Separate the Casings: With the metal key removed, you’ll notice a small slot. Carefully insert the flat-head screwdriver into this slot and gently pry the two halves of the key fob casing apart. Be patient and avoid using excessive force, as you don’t want to damage the casing.
- Access the Battery: Once the casing is separated, you’ll see the battery nestled inside. Take note of its position and polarity (the plus and minus signs) for easy replacement.
- Swap Out the Old Battery: Carefully remove the old battery and replace it with the new CR2032 battery, ensuring the polarity matches the original placement.
- Reassemble the Key Fob: Align the two halves of the casing and press them together firmly until you hear a satisfying click, indicating the casing is securely closed.
- Test Your Handiwork: Insert the metal key back into the fob and test all the buttons to make sure everything is functioning correctly.
