# 2018-2025 Jeep Wrangler Key Fob Battery Type and Replacement

The 2018-2025 Jeep Wrangler key fob takes a CR2032 coin cell. How to open the fob without breaking it, and which substitutions actually work.

**Quick answer**: The 2018-2025 Jeep Wrangler key fob takes a CR2032 coin-cell battery, available at any pharmacy, hardware store, or online for a few dollars.

## Replacing the 2018-2025 Jeep Wrangler 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.
- If the fob doesn't work after replacement, check that the battery is seated fully and the contacts weren't bent. Most vehicles do not need re-pairing after a battery change.

## Which Jeep Wrangler model years does this cover?

These key fob battery specifications apply to every Jeep Wrangler built from 2018 through 2025, the JL (3rd generation), off-road suv, solid front/rear axle (2-door; 4-door unlimited). Nothing in this specification changes between those model years.

## What changed during the 2018-2025 Jeep Wrangler

| Years | What changed |
| --- | --- |
| 2018 | JL launch; note that some dealers/titles carried over 'Wrangler JK' badging into 2018 for leftover previous-generation stock, a 2018-titled Wrangler may mechanically be a JK. Confirm by VIN/generation, not just model year. |
| 2019 | eTorque mild hybrid introduced as an option on the 2.0L turbo |
| 2020 | 3.0L EcoDiesel V6 added; eTorque became optional on the 3.6L V6 |
| 2021 | 4xe plug-in hybrid and Rubicon 392 (6.4L V8) both launch |
| 2022 | New High Tide and Beach special editions added; minor equipment shuffling across trims; 4xe becomes the only Wrangler variant offered in Europe |
| 2023 | Air conditioning becomes standard on all trims; Uconnect 4 replaces Uconnect 3 with a 7-in touchscreen standard (up from 5-in); Rubicon 20th Anniversary special edition |
| 2024 | eTorque dropped from the lineup entirely |
| 2025 | 3.6L V6 automatic reportedly phased toward manual-only on some trims as Jeep leans further into the 2.0L turbo and 4xe; verify current-year trim/engine availability before ordering parts |

## 2018-2025 Jeep Wrangler key fob battery: common questions

### What battery does the 2018-2025 Jeep Wrangler key fob take?

A single CR2032 coin cell.

### Can you use a CR2032 instead of a CR2025 in a 2018-2025 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 2018-2025 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.
