2012–2021 Jeep Grand Cherokee Key Fob Battery Type and Replacement

Which Jeep Grand Cherokee model years does this cover?

These key fob battery specifications apply to every Jeep Grand Cherokee built from 2012 through 2021 — the WK2 (4th generation), mid-size 2-row suv. 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 2012–2021 Jeep Grand Cherokee key fob take?

A single CR2032 coin cell.

Can you use a CR2032 instead of a CR2025 in a 2012–2021 Jeep Grand Cherokee 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 2012–2021 Jeep Grand Cherokee 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.
