Finding the Right Replacement Battery for Your 2011 Ford Flex Key Fob

How to Replace the Battery in Your 2011 Ford Flex Key Fob
Replacing the key fob battery is a quick and easy process that anyone can do at home with a few simple tools. Here’s a step-by-step guide:
- Locate the Key Release: On the back of your key fob, you’ll find a small button or tab. Press this to release the metal key blade.
- Open the Key Fob: With the key blade removed, you should see a small slot on the side of the key fob. Insert the tip of the key blade (or a small flathead screwdriver) into the slot and gently pry open the casing.
