How to open the fob without breaking it, and which substitutions actually work. **Quick answer**: The 2022-2025 Jeep Grand Cherokee key fob takes a CR2450 coin-cell battery, available at any pharmacy, hardware store, or online for a few dollars. ## Replacing the 2022-2025 Jeep Grand Cherokee 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 Grand Cherokee model years does this cover? These key fob battery specifications apply to every Jeep Grand Cherokee built from 2022 through 2025, the WL (5th generation), mid-size 2-row suv (giorgio-derived platform). Nothing in this specification changes between those model years. - [2022 Grand Cherokee](https://whichcarparts.com/cars/jeep/grand-cherokee/2022) - [2023 Grand Cherokee](https://whichcarparts.com/cars/jeep/grand-cherokee/2023) - [2024 Grand Cherokee](https://whichcarparts.com/cars/jeep/grand-cherokee/2024) - [2025 Grand Cherokee](https://whichcarparts.com/cars/jeep/grand-cherokee/2025) ## What changed during the 2022-2025 Jeep Grand Cherokee | Years | What changed | | --- | --- | | 2022 | WL launch: redesigned 2-row Grand Cherokee debuts alongside the continuing WK2 "Grand Cherokee WK"; 3.6L and 5.7L at launch, 4xe plug-in hybrid added as a mid-year addition | | 2023 | Final model year the 5.7L HEMI V8 was orderable in the 2-row Grand Cherokee (continued longer in the 3-row Grand Cherokee L) | | 2024 | 2-row lineup narrows to 3.6L Pentastar and 2.0L turbo 4xe only, no V8, no inline-six Hurricane option on the 2-row model | | 2025 | Carryover year on the 2-row; 4xe lineup expands with more trims | ## 2022-2025 Jeep Grand Cherokee key fob battery: common questions ### What battery does the 2022-2025 Jeep Grand Cherokee key fob take? A single CR2450 coin cell. ### Can you use a CR2032 instead of a CR2025 in a 2022-2025 Jeep Grand Cherokee key fob? This fob takes a CR2450, 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 2022-2025 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. ## Sources - [Jeep Garage forum, "WL V8 no longer an option in 2 Row Grand Cherokee"](https://www.jeepgarage.org/threads/wl-v8-no-longer-an-option-in-2-row-grand-cherokee.241866/) - [Autoevolution, "2023 Jeep Grand Cherokee Drops 5.7L HEMI V8, Grand Cherokee L Still Has It"](https://www.autoevolution.com/news/2023-jeep-grand-cherokee-drops-57l-hemi-v8-grand-cherokee-l-still-has-it-207348.html) - [Car and Driver, 2022 Jeep Grand Cherokee 4xe Hybrid specs](https://www.caranddriver.com/jeep/grand-cherokee-4xe-2022) - [NHTSA press release, Jeep Wrangler/Grand Cherokee 4xe high-voltage battery "park outside" recall](https://www.nhtsa.gov/press-releases/park-outside-recall-jeep-wrangler-phev) - [NHTSA recall 23V-352, steering intermediate shaft](https://static.nhtsa.gov/odi/rcl/2023/RCLRPT-23V352-5968.PDF) - [NHTSA recall 23V-413, rear coil spring detachment](https://static.nhtsa.gov/odi/rcl/2023/RCLRPT-23V413-6565.PDF) - [Jeep Garage forum, WL ESS (Stop/Start) auxiliary battery location thread](https://www.jeepgarage.org/threads/grand-cherokee-wl-ess-stop-start-system-battery-location.245932/) - [Cabral CDJR, How to Change the Battery on a Jeep Grand Cherokee (2025 model, under passenger/driver seat)](https://www.cabralchryslerjeepdodge.com/blog/how-to-change-the-battery-on-a-jeep-grand-cherokee) - [Fontana CDJR, Jeep Grand Cherokee Oil Type & Capacity Guide (2011-2026)](https://www.fontanacdjr.com/service-department/service-and-parts-tips/jeep-grand-cherokee-oil-type/) - [Reddit r/GrandCherokee, 2025 GC losing 5.7/3.6, 4-cyl turbo/4xe only discussion](https://www.reddit.com/r/GrandCherokee/comments/1cexvv9/2025_gc_losing_57_36_engines/) ## Other Jeep Grand Cherokee generations - [2012-2021 Jeep Grand Cherokee key fob battery](https://whichcarparts.com/cars/jeep/grand-cherokee/2012-2021/key-fob-battery) Or [compare all generations](https://whichcarparts.com/cars/jeep/grand-cherokee/key-fob-battery). ## More for the 2022-2025 Jeep Grand Cherokee - [Oil & filter](https://whichcarparts.com/cars/jeep/grand-cherokee/2022-2025/oil) - [Battery](https://whichcarparts.com/cars/jeep/grand-cherokee/2022-2025/battery) - [Tires & wheels](https://whichcarparts.com/cars/jeep/grand-cherokee/2022-2025/tires) - [Wiper blades](https://whichcarparts.com/cars/jeep/grand-cherokee/2022-2025/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/jeep/grand-cherokee/2022-2025/filters) - [Fluids](https://whichcarparts.com/cars/jeep/grand-cherokee/2022-2025/fluids) - [Service schedule](https://whichcarparts.com/cars/jeep/grand-cherokee/2022-2025/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/jeep/grand-cherokee/2022-2025/common-problems) - [Oil light reset](https://whichcarparts.com/cars/jeep/grand-cherokee/2022-2025/oil-reset) - [Specs](https://whichcarparts.com/cars/jeep/grand-cherokee/2022-2025/specs) Specifications vary with engine option, production date, and market.
