How to open the fob without breaking it, and which substitutions actually work. **Quick answer**: The 2019-2025 Nissan Altima key fob takes a CR2032 (Intelligent Key) coin-cell battery, available at any pharmacy, hardware store, or online for a few dollars. ## Replacing the 2019-2025 Nissan Altima 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 Nissan Altima model years does this cover? These key fob battery specifications apply to every Nissan Altima built from 2019 through 2025, the L34 (6th generation), mid-size sedan (fwd; awd available with 2.5l). Nothing in this specification changes between those model years. - [2019 Altima](https://whichcarparts.com/cars/nissan/altima/2019) - [2020 Altima](https://whichcarparts.com/cars/nissan/altima/2020) - [2021 Altima](https://whichcarparts.com/cars/nissan/altima/2021) - [2022 Altima](https://whichcarparts.com/cars/nissan/altima/2022) - [2023 Altima](https://whichcarparts.com/cars/nissan/altima/2023) - [2024 Altima](https://whichcarparts.com/cars/nissan/altima/2024) - [2025 Altima](https://whichcarparts.com/cars/nissan/altima/2025) ## What changed during the 2019-2025 Nissan Altima | Years | What changed | | --- | --- | | 2019 | Generation launch: PR25DD 2.5L with first-ever Altima AWD option, 2.0L VC-Turbo replaces the V6, ProPILOT Assist available, electronic parking brake standard | | 2020 | Platinum VC-Turbo's last year; Safety Shield 360 standard on more trims | | 2021 | VC-Turbo now SR-only | | 2022 | Carryover year: S/SV/SR/SR VC-Turbo/Platinum lineup and powertrains unchanged ahead of the 2023 facelift | | 2023 | Facelift: new grille and wheels, available 12.3-in touchscreen with wireless CarPlay, updated Intelligent Cruise | | 2024 | Carries over following the 2023 refresh; lineup unchanged (S, SV, SR, SR VC-Turbo, SL) ahead of the VC-Turbo's discontinuation for 2025 | | 2025 | Final model year.

A single CR2032 (Intelligent Key) coin cell. ### Can you use a CR2032 instead of a CR2025 in a 2019-2025 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 2019-2025 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) ## Other Nissan Altima generations - [2013-2018 Nissan Altima key fob battery](https://whichcarparts.com/cars/nissan/altima/2013-2018/key-fob-battery) - [2012 Nissan Altima key fob battery](https://whichcarparts.com/cars/nissan/altima/2012/key-fob-battery) Or [compare all generations](https://whichcarparts.com/cars/nissan/altima/key-fob-battery). ## More for the 2019-2025 Nissan Altima - [Oil & filter](https://whichcarparts.com/cars/nissan/altima/2019-2025/oil) - [Battery](https://whichcarparts.com/cars/nissan/altima/2019-2025/battery) - [Tires & wheels](https://whichcarparts.com/cars/nissan/altima/2019-2025/tires) - [Wiper blades](https://whichcarparts.com/cars/nissan/altima/2019-2025/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/nissan/altima/2019-2025/filters) - [Bulbs](https://whichcarparts.com/cars/nissan/altima/2019-2025/bulbs) - [Brakes](https://whichcarparts.com/cars/nissan/altima/2019-2025/brakes) - [Fluids](https://whichcarparts.com/cars/nissan/altima/2019-2025/fluids) - [Service schedule](https://whichcarparts.com/cars/nissan/altima/2019-2025/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/nissan/altima/2019-2025/common-problems) - [Oil light reset](https://whichcarparts.com/cars/nissan/altima/2019-2025/oil-reset) - [Specs](https://whichcarparts.com/cars/nissan/altima/2019-2025/specs) Specifications vary with engine option, production date, and market.
