## Full specifications by generation

The key fob battery on a Toyota Camry 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.

## Toyota Camry key fob battery: common questions

### What battery does the Toyota Camry key fob take?

A single CR2032 coin cell.

### Can you use a CR2032 instead of a CR2025 in a Toyota Camry 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 Toyota Camry 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.
