Ford Key Fob Battery Replacement
CR2032 across most Ford smart keys — the standard 20 × 3.2 mm cell.
Ford smart keys use CR2032 across most models. The 2-panel key splits at the seam; a coin or screwdriver blade works. Ford fobs are among the easiest to open — the trick is finding the seam notch.

FAQ
Which battery does a Ford key fob take?
CR2032 for the vast majority of Ford smart keys and remotes.
How do I open a Ford key fob?
Look for the seam notch near the key ring; most fobs split there without tools.
My Ford fob still does not work after a new cell?
Clean the contacts, check orientation; a battery that reads below 3.0V is weaker than the fob needs.
