Is your 2015 BMW 5 Series key fob acting up? Before you panic and schedule a pricey dealership visit, there’s a good chance a simple battery replacement is all you need. This quick guide will walk you through the process, getting you back on the road and in control in no time.
Why is My BMW Key Fob Battery Dying?
Like all batteries, your key fob’s power source has a limited lifespan. Factors like frequency of use, exposure to extreme temperatures, and even just time can contribute to its depletion. If your car only responds to the key fob when it’s very close or you’re experiencing inconsistent locking/unlocking, it’s a telltale sign that a dead battery is the likely culprit.
What Kind of Battery Does a 2015 BMW 5 Series Key Fob Take?
The 2015 BMW 5 Series key fob typically uses a CR2032 battery – a common type found at most electronics or automotive stores. You can grab one online or at your local supermarket.
How to Replace Your 2015 BMW 5 Series Key Fob Battery
Don’t worry, you don’t need to be a mechanic to tackle this DIY task. Here’s a step-by-step guide:
- Locate the release button: On the back of your key fob, you’ll find a small button or slider.
- Release the emergency key: Press the release button and gently slide out the emergency key blade.
- Open the key fob casing: Use the emergency key blade (or a small flat-head screwdriver) to carefully pry open the key fob casing along the indicated seam.
- Remove and replace the battery: Carefully remove the old battery and install the new CR2032 battery, ensuring the positive (+) side faces up.
- Reassemble the key fob: Align the two halves of the casing and press them firmly together until you hear a click.
- Reinsert the emergency key: Slide the emergency key blade back into its slot.
- Test the key fob: Ensure all buttons are functioning correctly.
