How to Replace a BMW Key Fob Battery

Picture this: You’re running late for a crucial meeting, you hit the unlock button on your BMW key fob, and…nothing. You try again, pressing harder this time, but still nothing. Panic sets in as you realize your key fob battery has died. Don’t worry; we’ve all been there. Replacing the battery in your BMW key fob is a simple task you can do yourself in a matter of minutes. This guide will walk you through the process step-by-step, so you can get back on the road and on with your day.

What You’ll Need to Replace Your BMW Key Fob Battery

Before you begin, gather the following items:

• A new CR2032 battery: These are readily available at most convenience stores, auto parts stores, and online.
• A small flat-head screwdriver: This is used to pry open the key fob casing.

Steps to Replace Your BMW Key Fob Battery

Here’s a simple, easy-to-follow guide on how to replace your BMW key fob battery:

1. Locate the release button: On the back of your BMW key fob, you’ll find a small, round release button. This button releases the metal key from the fob.
2. Release the metal key: Press the release button and gently slide the metal key out of the fob.
3. Identify the notch: With the metal key removed, you’ll see a small notch on the key fob casing. This notch is where you’ll insert your flat-head screwdriver.
4. Gently pry open the casing: Carefully insert the flat-head screwdriver into the notch and gently pry open the casing. Be careful not to use too much force, as this could damage the fob.
5. Remove the old battery: Once the casing is open, you’ll see the old CR2032 battery. Gently remove it by prying it up from the positive (+) side.
6. Insert the new battery: Place the new CR2032 battery in the compartment, ensuring the positive (+) side faces up.
7. Snap the casing shut: Align the two halves of the key fob casing and press them firmly together until you hear a snap, indicating they’re securely closed.
8. Reinsert the metal key: Slide the metal key back into its slot on the fob.
9. Test the key fob: Press the unlock or lock button on your key fob to ensure the new battery is working correctly.

Troubleshooting Tips

• If your key fob still doesn’t work after replacing the battery, try cleaning the battery contacts with a cotton swab and rubbing alcohol.
• Ensure the new battery is properly seated in the compartment and facing the correct direction.
• If you’ve tried these tips and your key fob is still not working, it’s possible there’s a more significant issue, and you may need to consult a qualified BMW technician.
