Experiencing issues with your 2015 BMW 4 Series key fob? A dead battery is often the culprit. This guide provides all the information you need to replace your key fob battery and get back on the road with ease.
How to Identify a Dying Key Fob Battery in Your BMW
Several telltale signs indicate your key fob battery needs replacing:
- Decreased Range: Do you find yourself standing closer to your car to lock or unlock the doors? This diminished range is a classic sign of a weakening battery.
- Intermittent Functioning: Is your key fob working sporadically? You may press the buttons multiple times before your BMW responds, suggesting the battery is nearing its end.
- Warning Messages: Your BMW’s dashboard might display warnings like “Key Fob Battery Low” or “Replace Key Fob Battery.”
If you’re experiencing any of these symptoms, it’s time to consider a battery swap.
What Type of Battery Does a 2015 BMW 4 Series Key Fob Use?
Your 2015 BMW 4 Series key fob utilizes a CR2032 battery, a common type found at most electronics stores.
Can I Replace the Battery Myself?
Absolutely! Replacing the key fob battery is a quick and straightforward process you can do at home. Here’s how:
- Gather your tools: You’ll only need a small flat-head screwdriver and a new CR2032 battery.
- Locate the battery compartment: On the back of your BMW key fob, you’ll find a small slot. Insert the flat-head screwdriver gently into this slot and pry open the key fob casing.
- Remove the old battery: Carefully remove the old CR2032 battery from its compartment.
- Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side faces upwards.
- Reassemble the key fob: Align the two halves of the key fob and press them together firmly until you hear a click.
“It’s always satisfying to empower car owners with the knowledge to perform simple maintenance tasks themselves,” says Mike Alvarez, a seasoned BMW technician. “Replacing the key fob battery is a perfect example of this – it saves you a trip to the dealership and puts you in control.”
Key Fob Still Not Working?
If you’ve replaced the battery and your key fob is still acting up, there might be other issues at play. Some potential culprits include:
- Key Fob Programming: Your key fob might need to be re-programmed to your BMW.
- Antenna Issues: Your BMW’s antenna, responsible for receiving the key fob’s signal, might be malfunctioning.
- Other Key Fob Malfunctions: Internal damage to your key fob can also cause operational issues.
