## Replacing the 2012-2016 Honda CR-V 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.

## 2012-2016 Honda CR-V key fob battery: common questions

### What battery does the 2012-2016 Honda CR-V key fob take?

A single CR1620 (remote-head key, 2012-2014); CR2032 (smart key on 2015-2016 EX and above). Check the old battery coin cell.

### Can you use a CR2032 instead of a CR2025 in a 2012-2016 Honda CR-V key fob?

This fob takes a CR1620 (remote-head key, 2012-2014); CR2032 (smart key on 2015-2016 EX and above). Check the old battery, 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 2012-2016 Honda CR-V 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.
