What Battery Does My 2007 BMW Key Fob Use?

How to Replace the Battery in a 2007 BMW Key Fob (Step-by-Step)
Here’s a detailed guide to replacing the battery in your 2007 BMW key fob:
-
Locate the Key Slot: Look for a small, rectangular slot on the side of your key fob. This slot is designed to release the metal key hidden inside.
-
Insert and Twist the Key: Insert your metal key into the slot and gently twist it. This will release a small panel on the back of the key fob.
-
Carefully Separate the Halves: Gently pry open the two halves of the key fob, being careful not to damage the internal components.
-
Identify and Remove the Old Battery: You’ll find the CR2032 battery inside. Use a small flathead screwdriver or your fingernail to carefully pry it out.

Insert the New Battery: Ensure the new battery is positioned correctly with the positive (+) side facing up. Gently press it into place.

Reassemble the Key Fob: Carefully align the two halves of the key fob and press them together firmly until you hear a click.

Test the Key Fob: Press each button on your key fob to ensure it’s functioning correctly. If everything works, congratulations! You’ve successfully replaced your 2007 BMW key fob battery.

If your key fob still doesn’t work after replacing the battery, try these tips:

Clean the Contacts: Over time, the battery contacts inside the key fob can accumulate dirt and grime. Use a cotton swab and rubbing alcohol to gently clean them.
