A single CR2450 (intelligent-access smart fob); base remote-head keys use CR2032, open the fob and match the old cell coin cell. ### Can you use a CR2032 instead of a CR2025 in a Ford F-150 key fob? This fob takes a CR2450 (intelligent-access smart fob); base remote-head keys use CR2032, open the fob and match the old cell, 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 Ford F-150 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 - [2022 Ford F-150 Owner's Manual (Ford service content), capacities and specifications](https://www.fordservicecontent.com/Ford_Content/Catalog/owner_information/2022-Ford-F-150-Owners-Manual-version-1_om_EN-US_10_2021.pdf) - [F150gen14 forum, 2021 5.0L 5W-30 / 7.7-qt sump change discussion (owner's manual excerpts)](https://www.f150gen14.com/forum/threads/2021-v8-oil-capacity.4358/) - [NHTSA recall 24V-635 chronology, 2.7L/3.0L EcoBoost intake valves](https://static.nhtsa.gov/odi/rcl/2024/RMISC-24V635-2546.pdf) - [Astro Ford / NHTSA, F-150 recall hub (driveshaft, trailer brake, axle, EBB campaigns)](https://www.astroford.com/recalls/ford-f-150-recalls.htm) - [Car and Driver, Ford EcoBoost intake-valve engine failure recall](https://www.caranddriver.com/news/a62044486/ford-f150-bronco-explorer-edge-lincoln-nautilus-aviator-engine-failure-recall/) - [fueleconomy.gov, 2023 Ford F-150 EPA ratings](https://www.fueleconomy.gov/feg/bymodel/2023_Ford_F150.shtml) - [Wheel-Size.com, 2022 Ford F-150 OE fitments](https://www.wheel-size.com/size/ford/f-150/2022/) - [Cars.com, 2021 F-150 towing capacities breakdown (14,000-lb max)](https://www.cars.com/articles/breaking-down-the-2021-ford-f-150s-towing-capacities-433112/) - [Motorcraft, MERCON ULV automatic transmission fluid (10R80)](https://www.motorcraft.com/us/en_us/home/our-products/chemicals-and-lubricants/transmission-fluid/mercon-ulv-automatic-transmission-fluids.html/100) ## Find your exact F-150 - [2025](https://whichcarparts.com/cars/ford/f-150/2025) - [2024](https://whichcarparts.com/cars/ford/f-150/2024) - [2023](https://whichcarparts.com/cars/ford/f-150/2023) - [2022](https://whichcarparts.com/cars/ford/f-150/2022) - [2021](https://whichcarparts.com/cars/ford/f-150/2021) - [2020](https://whichcarparts.com/cars/ford/f-150/2020) - [2019](https://whichcarparts.com/cars/ford/f-150/2019) - [2018](https://whichcarparts.com/cars/ford/f-150/2018) - [2017](https://whichcarparts.com/cars/ford/f-150/2017) - [2016](https://whichcarparts.com/cars/ford/f-150/2016) - [2015](https://whichcarparts.com/cars/ford/f-150/2015) - [2014](https://whichcarparts.com/cars/ford/f-150/2014) - [2013](https://whichcarparts.com/cars/ford/f-150/2013) - [2012](https://whichcarparts.com/cars/ford/f-150/2012) More Ford F-150 guides: - [Oil & filter](https://whichcarparts.com/cars/ford/f-150/oil) - [Battery](https://whichcarparts.com/cars/ford/f-150/battery) - [Tires & wheels](https://whichcarparts.com/cars/ford/f-150/tires) - [Wiper blades](https://whichcarparts.com/cars/ford/f-150/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/ford/f-150/filters) - [Bulbs](https://whichcarparts.com/cars/ford/f-150/bulbs) - [Brakes](https://whichcarparts.com/cars/ford/f-150/brakes) - [Fluids](https://whichcarparts.com/cars/ford/f-150/fluids) - [Service schedule](https://whichcarparts.com/cars/ford/f-150/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/ford/f-150/common-problems) - [Oil light reset](https://whichcarparts.com/cars/ford/f-150/oil-reset) - [Specs](https://whichcarparts.com/cars/ford/f-150/specs) Specifications vary with engine option, production date, and market.
