Ford Explorer Key Fob Battery Type and Replacement

Each row links to the full specification for that generation, including trim-by-trim breakdowns and the part numbers. Where engines within a generation differ, that page separates them.

The key fob battery on a Ford Explorer is set by its generation, not its model year, so each generation has one page carrying the complete figures, part numbers and fitment notes for every year it covers.

What battery does the Ford Explorer key fob take?

A single CR2450 (2020–2025 Intelligent Access fob; some manuals/fobs differ. Check the old cell when you open it) coin cell.

Can you use a CR2032 instead of a CR2025 in a Ford Explorer key fob?

Usually. Both are 20 mm across; the 2032 is 3.2 mm thick against the 2025's 2.5 mm, so it holds more charge but is a tighter fit and can strain the contacts in a shallow housing. If the case will not close cleanly, use the specified CR2450 (2020–2025 Intelligent Access fob; some manuals/fobs differ. Check the old cell when you open it).

How do you open a Ford Explorer key fob?

Slide out the mechanical emergency key first, which usually releases a catch, then part the halves with a plastic pry tool or a coin wrapped in tape. A screwdriver will mark the case and can crack the seam.
