Having trouble with your 2012 BMW 5 Series key fob? A dead battery is often the culprit. Don’t worry, replacing it is a fairly straightforward process you can handle yourself. This guide will walk you through everything you need to know about a 2012 Bmw 5 Series Key Fob Battery Replacement.
What You’ll Need
Before you get started, gather the following items:
- A new battery: Your 2012 BMW 5 Series key fob likely uses a CR2032 battery. These are widely available at most stores that sell batteries.
- A small flathead screwdriver: This will be used to pry open the key fob casing.
How to Replace the Battery
Now, let’s get to the heart of the matter – replacing that old battery. Follow these simple steps:
- Locate the release button: On the back of your key fob, you’ll find a small release button. Press this button to release the metal key blade.
- Separate the key fob halves: With the key blade removed, you’ll notice a small slot where the two halves of the key fob casing meet. Gently insert the flathead screwdriver into this slot and carefully pry the halves apart. Be careful not to use too much force, as this could damage 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 battery, ensuring the positive (+) side is facing up.
- Reassemble the key fob: Align the two halves of the casing and press them firmly together until they snap back into place.
- Reinsert the key blade: Slide the metal key blade back into its slot on the key fob.
- Test the key fob: Make sure everything is working properly by trying to lock and unlock your car doors using the key fob buttons.
Troubleshooting
If your key fob still isn’t working after replacing the battery, there could be other issues at play. Here are a few things to check:
- Battery Orientation: Ensure the new battery is installed correctly with the positive (+) side facing up.
- Key Fob Programming: In some cases, you may need to reprogram your key fob to your car after replacing the battery. Refer to your owner’s manual for instructions on how to do this.
- Other Issues: If you’re still experiencing problems, it’s possible there might be a more complex issue with your key fob, such as a malfunctioning circuit board. In such cases, it’s best to consult a qualified BMW technician.
Keeping Your Key Fob Healthy
A few simple tips can help prolong the life of your key fob battery:
- Avoid frequent drops: While key fobs are designed to withstand some impact, repeatedly dropping them can damage the battery and internal components.
- Store your key fob properly: Keep your key fob in a cool, dry place away from extreme temperatures and moisture.
- Replace the battery regularly: Even with careful use, key fob batteries have a limited lifespan. It’s a good idea to replace the battery every 2-3 years as a preventative measure.
In Conclusion
Replacing the battery in your 2012 BMW 5 Series key fob is a task most car owners can handle themselves. By following these simple steps, you can have your key fob back in working order in no time, saving yourself a trip to the dealership.
