If you’re experiencing issues with your 2017 BMW 330i key fob, a dead battery might be the culprit. Don’t worry, it’s a common issue with a simple fix. This comprehensive guide will walk you through everything you need to know about your 2017 Bmw 330i Key Fob Battery, from identifying the signs of a dying battery to replacing it yourself.
How to Tell if Your 2017 BMW 330i Key Fob Battery is Dying
A fading key fob battery can manifest in several ways. Recognizing these early warning signs can save you from a potentially frustrating lockout situation:
- Decreased Range: Is your car only responding to the key fob at very close range? This is often the first sign of a weakening battery.
- Intermittent Functioning: Are you experiencing inconsistent locking, unlocking, or trunk release? A dying battery can cause these functions to work erratically.
- Warning Messages: Your BMW may display warning messages on the dashboard, such as “Key Fob Battery Low,” alerting you to the need for a replacement.
- Physical Inspection: Sometimes, a visual inspection of the key fob battery (if accessible) can reveal corrosion or leakage, indicating it’s time for a new one.
What Type of Battery Does a 2017 BMW 330i Key Fob Use?
Your 2017 BMW 330i key fob uses a CR2032 battery, a common type of lithium coin battery readily available at most electronics stores, auto parts stores, and even online retailers.
DIY: Replacing Your 2017 BMW 330i Key Fob Battery
Replacing the battery in your key fob is a surprisingly easy task you can do yourself in minutes. Here’s a step-by-step guide:
- Locate the Battery Compartment: On the back of your key fob, you’ll find a small release button or slider. Press or slide it to detach the emergency key blade.
- Open the Fob: With the key blade removed, you’ll see a small slot. Gently pry open the key fob casing using a small flathead screwdriver or a coin.
- Remove the Old Battery: Carefully remove the old CR2032 battery. Note the battery’s orientation (+/-) for correct placement of the new one.
- Install the New Battery: Insert the new CR2032 battery into the compartment, ensuring the positive (+) side faces up.
- Reassemble the Fob: Align the two halves of the key fob casing and press them together until you hear a click, indicating it’s securely closed.
- Reinsert the Key Blade: Slide the emergency key blade back into its slot until it locks into place.
Troubleshooting: Key Fob Still Not Working?
If you’ve replaced the battery and your key fob is still acting up, don’t panic. Here are some additional troubleshooting steps:

- Check for Other Issues: Make sure there are no other issues with your vehicle’s battery or electrical system that could be interfering with the key fob’s signal.
