Identifying Your Key Fob Type

Before you begin, it’s important to determine which type of key fob your 2001 BMW 330i uses. There are two main possibilities:

Standard Key Fob: This features a rectangular shape with rounded edges and three buttons on one side.

The battery replacement process for each type is slightly different, so correctly identifying your key fob is crucial.

2001 BMW 330i Key Fob Battery Replacement: A Step-by-Step Guide

For Standard Key Fobs:

Locate the Release Button: On the back of your key fob, find the small, circular release button.
Release the Emergency Key: Press the release button and gently slide out the metal emergency key blade hidden within the fob.
Separate the Key Fob Halves: Using the edge of the emergency key blade or a small flat-head screwdriver, carefully pry open the key fob casing along the seam. You should hear a click when it separates.
Identify the Battery: Inside, you’ll see the battery, typically a CR2032 3-volt lithium battery.
Remove and Replace: Gently remove the old battery and install the new one, ensuring the positive (+) side faces up.
Reassemble: Align the two halves of the key fob and press firmly until they snap back together.
Test the Key Fob: Check if all buttons are functioning correctly.

For Diamond Key Fobs:

Locate the Battery Compartment: The battery compartment is located on the back of the fob, typically covered by a small panel.
Open the Compartment: Use a small flat-head screwdriver or a coin to gently pry open the battery compartment cover.
Replace the Battery: Remove the old battery (likely a CR2032) and install the new one, ensuring the positive (+) side is facing up.
Close the Compartment: Snap the battery compartment cover back into place.
Test the Key Fob: Verify that all buttons are working properly.

Troubleshooting Tips

Key Fob Still Not Working? Ensure you’ve installed the new battery correctly, with the positive (+) side facing up. If problems persist, there may be an issue with the key fob itself, and a trip to your BMW dealership or a qualified automotive locksmith might be necessary.
Programming Your Key Fob: In most cases, your 2001 BMW 330i won’t require key fob reprogramming after a battery replacement. However, if the key fob still doesn’t function correctly, you may need to re-synchronize it with your car. Consult your owner’s manual or seek professional assistance for the specific programming procedure.
