Ford Fusion Key Fob Battery Replacement: Step-by-Step Guide to Easy Access, Removal, and Installation

If you own a Ford Fusion manufactured from 2017 onwards and need to change the fob key battery, this guide is for you. The process is relatively simple and requires minimal tools. Here’s a step-by-step tutorial on how to do it.

Step 1: Accessing the Back of the Battery

Start by pressing the button at the top of the fob to remove the internal valet key. Then, flip the fob over to reveal a backing that needs to be popped off. To do this, you can use a flathead screwdriver or simply pry it off with the valet key.

Step 2: Removing the Old Battery

After removing the back cover, you’ll see the battery that needs to be replaced. There’s a small hole to access the battery. Use a paper clip or a small flathead screwdriver to pop the old battery out.

Step 3: Installing the New Battery

When inserting the new battery, ensure that the positive side is facing towards you. The positive side should have the battery rating on it and a plus sign.

Step 4: Reassembling the Fob

Once the new battery is in place, reattach the backing by inserting the notch first and then snapping everything back into place. Finally, put the valet key back in, and you’re done!

It’s important to note that the battery you’ll need for the Ford Fusion or modern smart key fob is a CR 2450.

That’s all there is to it! With these simple steps, you can easily change the fob key battery in your Ford Fusion. Thanks for reading!
