A dead key fob battery can really throw a wrench in your day, leaving you stranded and frustrated. But don’t worry, changing the battery in your BMW key fob is a surprisingly simple task that you can tackle yourself. This guide will walk you through the process step-by-step, so you can get back on the road in no time.
Let’s face it, we’ve all been there: you’re rushing to get somewhere important, only to find that your BMW key fob is unresponsive. Before you panic and start searching for expensive replacements, consider this: it might just be a dead battery.
What You’ll Need:
- A brand new CR2032 battery (you can find these at most supermarkets, electronics stores, or online)
- A small flathead screwdriver or a plastic pry tool
How to Change the Battery in Your BMW Key Fob:
-
Locate the release button. On the back of your BMW key fob, you’ll find a small, usually metallic button. This is the release button for the emergency key.
-
Release the emergency key. Gently press the release button and slide the emergency key out of the key fob.
-
Open the key fob casing. With the emergency key removed, you can use it or a small flathead screwdriver to pry open the key fob casing. Carefully insert the tool into the groove where the emergency key was and gently twist to separate the two halves of the casing.
-
Replace the battery. Inside the key fob, you’ll see the old CR2032 battery. Carefully remove it and replace it with the new one, making sure to match the positive (+) and negative (-) sides.
-
Reassemble the key fob. Align the two halves of the key fob casing and press them firmly together until you hear a click, indicating that they’re securely closed.
-
Reinsert the emergency key. Slide the emergency key back into its slot on the key fob.
-
Test your key fob. Try locking and unlocking your BMW to make sure the new battery is working correctly.
Still Having Trouble?
While changing the battery in your BMW key fob is generally straightforward, there might be instances where you encounter difficulties. Here are some common issues and solutions:
Problem: The key fob still doesn’t work after replacing the battery.
Solution:
- Double-check that you’ve inserted the battery correctly, with the positive (+) and negative (-) sides aligned properly.
- Try using a different brand of CR2032 battery, as some brands might be of higher quality than others.
- There could be an issue with the key fob itself, such as a malfunctioning circuit board. In this case, it’s best to consult your BMW dealership or a qualified automotive locksmith.
Problem: I can’t seem to pry open the key fob casing.
Solution:
- Make sure you’re applying pressure in the right spot. Refer to your car’s manual if needed.
- The casing might be stuck due to dirt or debris. Try cleaning the groove with a cotton swab and some rubbing alcohol before trying again.
- If you’re still having trouble, consider seeking assistance from a professional to avoid damaging the key fob.
Tips for Maintaining Your BMW Key Fob Battery Life:
- Avoid exposing your key fob to extreme temperatures, as this can shorten the battery life.
- Don’t keep your key fob in the same pocket or bag as your phone, as the electromagnetic signals can drain the battery.
- If you’re not using your BMW for an extended period, consider removing the battery from the key fob to prevent any potential for leakage or damage.
Changing the battery in your BMW key fob is a quick and easy DIY task that can save you time, money, and a whole lot of hassle. By following the steps outlined in this guide, you can regain control of your BMW and get back on the road with confidence.
