How to open the fob without breaking it, and which substitutions actually work. **Quick answer**: The 2015-2020 Ford F-150 key fob takes a CR2032 (flip key); two CR2025 (2015-17 intelligent-access fob); CR2450 (2018+ smart fob), open the fob and match the old cell coin-cell battery, available at any pharmacy, hardware store, or online for a few dollars. ## Replacing the 2015-2020 Ford F-150 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 Ford F-150 model years does this cover? These key fob battery specifications apply to every Ford F-150 built from 2015 through 2020, the 13th generation (2015-2020, aluminum body), full-size pickup (aluminum body, steel frame). Nothing in this specification changes between those model years. - [2015 F-150](https://whichcarparts.com/cars/ford/f-150/2015) - [2016 F-150](https://whichcarparts.com/cars/ford/f-150/2016) - [2017 F-150](https://whichcarparts.com/cars/ford/f-150/2017) - [2018 F-150](https://whichcarparts.com/cars/ford/f-150/2018) - [2019 F-150](https://whichcarparts.com/cars/ford/f-150/2019) - [2020 F-150](https://whichcarparts.com/cars/ford/f-150/2020) ## What changed during the 2015-2020 Ford F-150 | Years | What changed | | --- | --- | | 2015 | All-new aluminum body (~700 lb lighter); 2.7L EcoBoost debuts; 5.0L drops to 7.7 qt oil capacity (through 2017) | | 2017 | Raptor returns (450-hp 3.5L HO); second-gen PFDI 3.5L EcoBoost + 10R80 10-speed introduced (MERCON ULV fluid) | | 2018 | Facelift: 3.3L replaces 3.5L NA base engine, 5.0L rises to 395 hp and 8.8 qt capacity, 10-speed spreads to 2.7L/5.0L, Auto Start-Stop standard on EcoBoost | | 2018-2020 | 3.0L Power Stroke diesel offered (from mid-2018) | | 2020 | Final year of the generation; carryover mechanicals | ## 2015-2020 Ford F-150 key fob battery: common questions ### What battery does the 2015-2020 Ford F-150 key fob take? A single CR2032 (flip key); two CR2025 (2015-17 intelligent-access fob); CR2450 (2018+ smart fob), open the fob and match the old cell coin cell. ### Can you use a CR2032 instead of a CR2025 in a 2015-2020 Ford F-150 key fob? Usually. Both are 20 mm across; the 2032 is 3.2 mm thick against the 2025's 2.5 mm, so it holds more charge but is a tighter fit and can strain the contacts in a shallow housing. If the case will not close cleanly, use the specified CR2032 (flip key); two CR2025 (2015-17 intelligent-access fob); CR2450 (2018+ smart fob), open the fob and match the old cell. ### How do you open a 2015-2020 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 - [Blauparts / Ford owner-manual data, 13th-gen oil capacities by engine](https://www.blauparts.com/ford-f-150-oil-change-kit-2018-20-5-0l-v8-5w20.html) - [NOLN Tech Spec, 2018 Ford F-150 service specifications](https://www.noln.net/topics/news/article/11496835/tech-spec-2018-ford-f-150-2018-03-01) - [NHTSA recall 20V-332, brake master cylinder, 2014-2017 F-150 3.5L EB](https://static.nhtsa.gov/odi/rcl/2020/RCLRPT-20V332-1472.PDF) - [NHTSA recall 17V-652 / Ford 17S33, door latch](https://static.nhtsa.gov/odi/rcl/2017/RCMN-17V652-3541.pdf) - [NHTSA recall 18V-568, seat belt pretensioners](https://static.nhtsa.gov/odi/rcl/2018/RCLRPT-18V568-3762.PDF) - [Motorcraft FL-2081 diesel oil filter fitment (2018-2021 3.0L Power Stroke)](https://puredieselpower.com/ford/2018-2021-f-150-powerstroke/2018-2021-ford-3.0l-powerstroke-upgraded-replacement-parts/18-21-ford-f-150-3.0l-powerstroke-ford-motocraft-oil-filter-fl-2081) - [fueleconomy.gov, 2018 Ford F-150 EPA ratings](https://www.fueleconomy.gov/feg/bymodel/2018_Ford_F150.shtml) - [Hardrock Offroad, F-150 OEM wheel/tire fitment guide by generation](https://hardrockoffroad.com/fitment-guides/ford-f150/) - [BatteryMart / Interstate, 2015-2020 F-150 H6/H7 battery fitment](https://www.batterymart.com/c-ford-f-150-car-battery.html) ## Other Ford F-150 generations - [2021-2025 Ford F-150 key fob battery](https://whichcarparts.com/cars/ford/f-150/2021-2025/key-fob-battery) - [2012-2014 Ford F-150 key fob battery](https://whichcarparts.com/cars/ford/f-150/2012-2014/key-fob-battery) Or [compare all generations](https://whichcarparts.com/cars/ford/f-150/key-fob-battery). ## More for the 2015-2020 Ford F-150 - [Oil & filter](https://whichcarparts.com/cars/ford/f-150/2015-2020/oil) - [Battery](https://whichcarparts.com/cars/ford/f-150/2015-2020/battery) - [Tires & wheels](https://whichcarparts.com/cars/ford/f-150/2015-2020/tires) - [Wiper blades](https://whichcarparts.com/cars/ford/f-150/2015-2020/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/ford/f-150/2015-2020/filters) - [Bulbs](https://whichcarparts.com/cars/ford/f-150/2015-2020/bulbs) - [Brakes](https://whichcarparts.com/cars/ford/f-150/2015-2020/brakes) - [Fluids](https://whichcarparts.com/cars/ford/f-150/2015-2020/fluids) - [Service schedule](https://whichcarparts.com/cars/ford/f-150/2015-2020/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/ford/f-150/2015-2020/common-problems) - [Oil light reset](https://whichcarparts.com/cars/ford/f-150/2015-2020/oil-reset) - [Specs](https://whichcarparts.com/cars/ford/f-150/2015-2020/specs) Specifications vary with engine option, production date, and market.
