2020–2025 Toyota Highlander Key Fob Battery Type and Replacement

Which Toyota Highlander model years does this cover?

These key fob battery specifications apply to every Toyota Highlander built from 2020 through 2025 — the XU70 (4th generation), mid-size 3-row crossover suv (tnga-k platform). Nothing in this specification changes between those model years. Pick your year for the engines it offered, what changed that year, and the problems recorded against it.

What battery does the 2020–2025 Toyota Highlander key fob take?

A single CR2032 coin cell.

Can you use a CR2032 instead of a CR2025 in a 2020–2025 Toyota Highlander 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 2020–2025 Toyota Highlander 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.
