If you’re experiencing issues with your 2015 BMW 328i key fob, like decreased range or unresponsive buttons, there’s a good chance the battery needs replacing. Don’t worry, it’s a fairly simple process you can handle at home in minutes.
Recognizing a Dying Key Fob Battery
Before we jump into the replacement, how can you be sure it’s actually the battery? Here are some telltale signs:
- Reduced Range: You need to be much closer to your car for the key fob to unlock it.
- Intermittent Functioning: The buttons work sometimes, but not always.
- Warning Message: Your BMW might display a “Key Fob Battery Low” message on the dashboard.
If any of these sound familiar, a new battery is likely the answer.
What You’ll Need for the Replacement
The good news is you only need a couple of things:
- A new CR2032 battery: You can find these at most hardware stores, auto parts stores, or online.
- A small flat-head screwdriver: This will help you open the key fob.
Replacing the Battery: A Step-by-Step Guide
Ready to get started? Here’s a simple guide:
- Locate the release button: On the back of your key fob, find the small button near the key ring.
- Release the metal key: Press the release button and gently pull out the metal key.
- Open the key fob: Insert the flat-head screwdriver into the slot you just revealed by removing the metal key. Gently pry open the two halves of the key fob.
- Remove the old battery: Carefully lift out the old CR2032 battery.
- Insert the new battery: Make sure the positive (+) side of the new battery is facing up, the same way the old battery was positioned.
- Close the key fob: Align the two halves of the key fob and press them firmly together until you hear a click.
- Reinsert the metal key: Slide the metal key back into its slot until it locks into place.
That’s it! Your key fob should be working like new.
Troubleshooting Tips
Still having issues? Here are a couple of things to check:
- Battery Orientation: Make sure the new battery is inserted correctly with the positive (+) side facing up.
- Clean Contacts: Use a cotton swab and a bit of rubbing alcohol to clean the battery contacts inside the key fob. This can improve connectivity.
When to Consult a Professional
If you’ve replaced the battery and are still experiencing problems, there might be another issue with your key fob, such as a faulty button or a programming problem. In these cases, it’s best to consult a qualified BMW technician or an experienced automotive locksmith.
Keeping Your Key Fob Healthy
To prolong the life of your key fob battery, avoid:
- Dropping your key fob: Impacts can damage the battery and internal components.
- Exposing your key fob to extreme temperatures: Extreme heat or cold can shorten battery life.
- Leaving your key fob unused for long periods: Regular use can actually help keep the battery charged.
