A single CR2032 coin cell. ### Can you use a CR2032 instead of a CR2025 in a 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 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. ## Sources - [NHTSA Part 573 Safety Recall Report 20V-124, clutch pressure plate](https://static.nhtsa.gov/odi/rcl/2020/RCLRPT-20V124-8022.PDF) - [NHTSA Part 573 Safety Recall Report 23V-787, 4xe HV battery fire risk](https://static.nhtsa.gov/odi/rcl/2023/RCLRPT-23V787-2073.PDF) - [The Drive, NHTSA opens investigation into 2018-2019 JL frame welds/steering](https://www.thedrive.com/news/29962/nhtsa-opens-investigation-on-2018-2019-jeep-wrangler-over-faulty-frame-welds) - [Go-Parts, 2019-2024 Jeep Wrangler steering damper guide, TSB 23-079-23](https://www.go-parts.com/garage/ps-2019-2024-jeep-wrangler-steering-damper) - [xtremediesel.com, 2020-2023 Wrangler 3.0 EcoDiesel oil spec (MS-12991, 5W-40, 9.0 qt)](https://www.xtremediesel.com/jeep-2020-wrangler-ecodiesel/fluids-filters/engine-oil) - [Victorville Motors / Fontana CDJR, Wrangler oil type & capacity by engine and year](https://www.victorvillemotors.com/service-department/service-tips/jeep-wrangler-oil-type/) - [Green Car Reports, 2021 Wrangler 4xe EPA electric range (22 mi) and MPGe (49)](https://www.greencarreports.com/news/1131650_2021-jeep-wrangler-4xe-plug-in-hybrid-rated-for-22-electric-miles) - [MotorTrend, 2021 Rubicon 392 EPA fuel economy (13/17/14 mpg)](https://www.motortrend.com/news/2021-jeep-wrangler-rubicon-392-fuel-economy-mpg) - [DrivingLine / MotorTrend, Xtreme Recon package factory 35-in tire spec (LT315/70R17)](https://www.drivingline.com/articles/37-s-and-no-lift-jeep-wrangler-unlimited-rubicon-392-xtreme-recon/) - [4 Wheel Parts, JL factory tire sizes by trim (Sport 245/75R17, Rubicon 285/70R17)](https://www.4wheelparts.com/articles/what-tires-fit-on-the-jeep-wrangler-jl) - [jlwranglerforums.com, JL cabin air filter part number and location](https://www.jlwranglerforums.com/forum/threads/cabin-air-filter-part-servicing.5432/) - [Edmunds, 2018 Jeep Wrangler specs (fuel tank, curb weight, EPA mpg)](https://www.edmunds.com/jeep/wrangler/2018/features-specs/) ## Find your exact Wrangler - [2025](https://whichcarparts.com/cars/jeep/wrangler/2025) - [2024](https://whichcarparts.com/cars/jeep/wrangler/2024) - [2023](https://whichcarparts.com/cars/jeep/wrangler/2023) - [2022](https://whichcarparts.com/cars/jeep/wrangler/2022) - [2021](https://whichcarparts.com/cars/jeep/wrangler/2021) - [2020](https://whichcarparts.com/cars/jeep/wrangler/2020) - [2019](https://whichcarparts.com/cars/jeep/wrangler/2019) - [2018](https://whichcarparts.com/cars/jeep/wrangler/2018) - [2017](https://whichcarparts.com/cars/jeep/wrangler/2017) - [2016](https://whichcarparts.com/cars/jeep/wrangler/2016) - [2015](https://whichcarparts.com/cars/jeep/wrangler/2015) - [2014](https://whichcarparts.com/cars/jeep/wrangler/2014) - [2013](https://whichcarparts.com/cars/jeep/wrangler/2013) - [2012](https://whichcarparts.com/cars/jeep/wrangler/2012) More Jeep Wrangler guides: - [Oil & filter](https://whichcarparts.com/cars/jeep/wrangler/oil) - [Battery](https://whichcarparts.com/cars/jeep/wrangler/battery) - [Tires & wheels](https://whichcarparts.com/cars/jeep/wrangler/tires) - [Wiper blades](https://whichcarparts.com/cars/jeep/wrangler/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/jeep/wrangler/filters) - [Bulbs](https://whichcarparts.com/cars/jeep/wrangler/bulbs) - [Brakes](https://whichcarparts.com/cars/jeep/wrangler/brakes) - [Fluids](https://whichcarparts.com/cars/jeep/wrangler/fluids) - [Service schedule](https://whichcarparts.com/cars/jeep/wrangler/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/jeep/wrangler/common-problems) - [Oil light reset](https://whichcarparts.com/cars/jeep/wrangler/oil-reset) - [Specs](https://whichcarparts.com/cars/jeep/wrangler/specs) Specifications vary with engine option, production date, and market.
