In just a few minutes, you’ll be back to enjoying seamless entry and ignition. Let’s get started!

What You’ll Need

Before we dive in, gather a few basic tools:

A brand new CR2032 battery (you can find these at most supermarkets, electronics stores, and auto parts stores)

Step-by-Step Guide: Replacing Your 2014 BMW Key Fob Battery

Follow these simple steps to replace your BMW key fob battery like a pro:

Locate the Release Button: Take a close look at your BMW key fob. You’ll notice a small, rectangular button on the back, usually near the key ring. This is the release button for the emergency key.
Release the Emergency Key: Gently press the release button and carefully slide the emergency key out of the fob.
Open the Key Fob: With the emergency key removed, you’ll see a small slot. Insert your flathead screwdriver or pry tool into this slot and gently twist or lever it open. The key fob should separate into two halves. Be careful not to use excessive force, as this could damage the fob.
Replace the Battery: Inside the key fob, you’ll find the CR2032 battery. Carefully remove it by gently prying it up from the positive (+) side, which is usually marked. Insert the new battery, making sure the positive (+) side faces up, just like the old one.
