2012–2017 Jeep Wrangler Key Fob Battery Type and Replacement

Which Jeep Wrangler model years does this cover?

These key fob battery specifications apply to every Jeep Wrangler built from 2012 through 2017 — the JK (2007–2018 platform; US 2012–2017 shown), off-road suv, solid front/rear axle (2-door; 4-door unlimited). 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 changed during the 2012–2017 Jeep Wrangler

• 20123.6L Pentastar V6 replaces the old 3.8L V6 across the JK lineup; 5-speed automatic (W5A580) replaces the 4-speed

What battery does the 2012–2017 Jeep Wrangler key fob take?

A single CR2032 coin cell.

Can you use a CR2032 instead of a CR2025 in a 2012–2017 Jeep Wrangler 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 2012–2017 Jeep Wrangler 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.
