- Decreased range: You find yourself having to stand closer to your car for the key fob to work.
- Intermittent functionality: The key fob works sometimes, but not always.
- Dim or flashing key fob light: The LED indicator on your key fob is weaker than usual or flickers instead of shining brightly.
- Slow response: There’s a noticeable delay between pressing a button on your key fob and the car responding.
If any of these situations sound familiar, it’s time to roll up your sleeves and tackle that battery replacement.
DIY Battery Replacement: Quick and Easy
Replacing the battery in your 2015 BMW M3 key fob is a surprisingly simple task that won’t require a trip to the dealership. Here’s a step-by-step guide to get you started:
- Gather your tools: You’ll only need a few things: a small flathead screwdriver, a fresh CR2032 battery (easily found at most supermarkets, drugstores, and online retailers), and your trusty 2015 BMW M3 key fob.
- Open the key fob: Locate the small groove on the side of the key fob. Insert the flathead screwdriver and gently pry open the casing. It should separate into two halves.
- Replace the battery: Carefully remove the old CR2032 battery from its slot. Insert the new battery, ensuring the positive (+) side faces up.
- Reassemble the key fob: Align the two halves of the key fob casing and press them firmly together until you hear a click.
- Test it out: Try locking and unlocking your car to confirm your new battery is working properly.
Pro Tip: While you have the key fob open, take a moment to clean the inside with a soft, dry cloth. This can help ensure optimal performance.
