A single CR2032 (Intelligent Key) coin cell. ### Can you use a CR2032 instead of a CR2025 in a Nissan Altima key fob? This fob takes a CR2032 (Intelligent Key), 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 Nissan Altima 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 - [Nissan USA Newsroom, 2019 Altima specifications (oil capacities, weights, fuel tank)](https://usa.nissannews.com/en-US/releases/release-215892633e2d484998bf260cfe01349c-2019-nissan-altima-specifications) - [AMSOIL product lookup, 2019 Altima 2.5L PR25DD (0W-20, 5.4 qt, drain plug 22-29 ft-lbs)](https://www.amsoil.com/lookup/auto-and-light-truck/2019/nissan-datsun/altima/2-5l-4-cyl-engine-code-pr25dd-d/) - [NHTSA recall 25V-437, VC-Turbo engine bearings](https://static.nhtsa.gov/odi/rcl/2025/RCLRPT-25V437-0139.pdf) - [NHTSA recalls by vehicle, 2019 Nissan Altima (18V-922, 19V-235, 19V-316, 19V-654, 23V-628)](https://api.nhtsa.gov/recalls/recallsByVehicle?make=nissan&model=altima&modelYear=2019) - [Nissan parts, 16546-6CA0A engine air filter fitment (2019-2025 Altima)](https://nissan.oempartsonline.com/oem-parts/nissan-air-filter-165466ca0a) - [Nissan parts, 22401-6LD1C spark plug (2019-2025)](https://parts.nissanusa.com/parts/nissan-spark-plug-224016ld1c) - [TirePressure.org, 2019 Nissan Altima placard pressures](https://tirepressure.org/nissan/altima/2019) - [fueleconomy.gov, 2019 Nissan Altima EPA ratings](https://www.fueleconomy.gov/feg/bymodel/2019_Nissan_Altima.shtml) - [Cars.com, Nissan drops VC-Turbo from 2025 Altima](https://www.cars.com/articles/nissan-axes-turbocharged-engine-from-2025-altima-adds-sv-special-edition-488081/) - [Goodyear tire lookup, 2019 Altima OE sizes by trim](https://www.goodyear.com/en-us/vehicles/Nissan/Altima/2019) ## Find your exact Altima - [2025](https://whichcarparts.com/cars/nissan/altima/2025) - [2024](https://whichcarparts.com/cars/nissan/altima/2024) - [2023](https://whichcarparts.com/cars/nissan/altima/2023) - [2022](https://whichcarparts.com/cars/nissan/altima/2022) - [2021](https://whichcarparts.com/cars/nissan/altima/2021) - [2020](https://whichcarparts.com/cars/nissan/altima/2020) - [2019](https://whichcarparts.com/cars/nissan/altima/2019) - [2018](https://whichcarparts.com/cars/nissan/altima/2018) - [2017](https://whichcarparts.com/cars/nissan/altima/2017) - [2016](https://whichcarparts.com/cars/nissan/altima/2016) - [2015](https://whichcarparts.com/cars/nissan/altima/2015) - [2014](https://whichcarparts.com/cars/nissan/altima/2014) - [2013](https://whichcarparts.com/cars/nissan/altima/2013) - [2012](https://whichcarparts.com/cars/nissan/altima/2012) More Nissan Altima guides: - [Oil & filter](https://whichcarparts.com/cars/nissan/altima/oil) - [Battery](https://whichcarparts.com/cars/nissan/altima/battery) - [Tires & wheels](https://whichcarparts.com/cars/nissan/altima/tires) - [Wiper blades](https://whichcarparts.com/cars/nissan/altima/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/nissan/altima/filters) - [Bulbs](https://whichcarparts.com/cars/nissan/altima/bulbs) - [Brakes](https://whichcarparts.com/cars/nissan/altima/brakes) - [Fluids](https://whichcarparts.com/cars/nissan/altima/fluids) - [Service schedule](https://whichcarparts.com/cars/nissan/altima/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/nissan/altima/common-problems) - [Oil light reset](https://whichcarparts.com/cars/nissan/altima/oil-reset) - [Specs](https://whichcarparts.com/cars/nissan/altima/specs) Specifications vary with engine option, production date, and market.
