# 2012 Ford Fusion Key Fob Battery Type and Replacement

The 2012 Ford Fusion key fob takes a CR2032 coin cell. How to open the fob without breaking it, and which substitutions actually work.

**Quick answer**: The 2012 Ford Fusion key fob takes a CR2032 coin-cell battery, available at any pharmacy, hardware store, or online for a few dollars.

## Replacing the 2012 Ford Fusion key fob battery

- Pry the fob open gently at the seam with a small flathead screwdriver or a coin, working around the edge. Many fobs have a hidden release slot near the key ring or emergency-key blade.
- Note the battery orientation (usually positive side up) before removing the old cell.
- Avoid touching the new battery's faces with bare fingers; skin oils can shorten its life.
- If the fob doesn't work after replacement, check that the battery is seated fully and the contacts weren't bent. Most vehicles do not need re-pairing after a battery change.

## Which Ford Fusion model years does this cover?

## 2012 Ford Fusion key fob battery: common questions

### What battery does the 2012 Ford Fusion key fob take?

A single CR2032 coin cell.

### Can you use a CR2032 instead of a CR2025 in a 2012 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 2012 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.
