## Ford Fusion key fob battery: common questions

### What battery does the Ford Fusion key fob take?

A single CR2032 coin cell.

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

This fob takes a CR2032, so start there. The two cells share a 20 mm diameter but differ in thickness, and the thicker one does not always seat in a housing built for the thinner.

### How do you open a Ford Fusion 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.
