Is your 2010 Ford Fusion key fob not working as reliably as it used to? You might be facing a common issue: a dead or dying key fob battery. Fortunately, replacing the battery in your Ford Fusion key fob is a straightforward process you can easily do yourself. This guide will walk you through each step, ensuring you can get your key fob back in top shape quickly.
Before you start, it’s important to know the type of battery your key fob uses. For the 2010 Ford Fusion key fob, you’ll typically need a CR2032 battery. These batteries are widely available at drugstores, supermarkets, and online retailers. Keeping the correct battery type in mind will save you a trip back to the store.
Now, let’s get to the battery replacement process:
-
Locate the Notch: On your Ford Fusion key fob, find the small notch. This is usually located on the side or bottom of the fob.
-
Open the Fob: Use a small flathead screwdriver or a similar tool. Gently insert the screwdriver into the notch and twist to pry the key fob casing open. Be careful not to apply too much force, as you could damage the plastic casing.

Remove the Old Battery: Once the key fob is open, you’ll see the battery. Note the orientation of the battery (usually positive side up). Carefully remove the old CR2032 battery. You might be able to use your fingertip or the edge of the screwdriver to gently pry it out.

Insert the New Battery: Take your new CR2032 battery and insert it into the battery compartment. Make sure the orientation is correct – the positive (+) side should usually face upwards.
-
Close the Fob: Carefully snap the two halves of the key fob casing back together. Ensure they are firmly closed and that there are no gaps.
-
Test Your Key Fob: Press a button on your key fob to test if it’s working. The doors should lock or unlock, or the panic alarm should sound, depending on the button you press.
If your key fob still doesn’t work after replacing the battery, there might be another issue. In some cases, especially after a battery has been dead for a while, you might need to reprogram the key fob to your 2010 Ford Fusion. Refer to the original programming instructions for remote only and remote key combo for steps on how to do this. However, battery replacement solves the issue in most cases, getting you back on the road with a functioning key fob.
