A single CR2032 (Intelligent Key) coin cell. ### Can you use a CR2032 instead of a CR2025 in a Nissan Sentra 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 Sentra 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 - [2021 Nissan Sentra Owner's Manual (capacities, NS-3, bulbs, schedule, CR2032, tires)](https://www.nissan-techinfo.com/refgh0v/og/sentra/2021-Nissan-Sentra.pdf) - [NHTSA recall 23V-581, tie rod assembly, 2020-2022 Sentra](https://www.nhtsa.gov/vehicle/2021/NISSAN/SENTRA/recalls) - [NHTSA recalls, 2024/2025 Sentra (driveshaft 24V-304, 26V-410)](https://www.nhtsa.gov/vehicle/2024/NISSAN/SENTRA/recalls) - [AMSOIL lookup, 2020 Sentra 2.0L MR20DD (0W-20, drain plug 22-29 ft-lb)](https://www.amsoil.com/lookup/auto-and-light-truck/2020/nissan-datsun/sentra/2-0l-4-cyl-engine-code-mr20dd-b/) - [KBB / Car and Driver, 2020 Sentra specs (149 hp, 3,047 lb curb weight)](https://www.caranddriver.com/nissan/sentra/specs/2020/nissan_sentra_nissan-sentra_2020) - [Go-Parts, 2020-2025 Sentra rear brakes (260mm discs SV/SR, drums S)](https://www.go-parts.com/garage/brakes-rear-nissan-sentra-2020-2025) - [Nissan parts, 15208-65F0E oil filter](https://parts.nissanusa.com/parts/nissan-oil-filter-1520865f0e) - [fueleconomy.gov, 2021 Sentra EPA ratings](https://www.fueleconomy.gov/feg/bymodel/2021_Nissan_Sentra.shtml) ## Find your exact Sentra - [2025](https://whichcarparts.com/cars/nissan/sentra/2025) - [2024](https://whichcarparts.com/cars/nissan/sentra/2024) - [2023](https://whichcarparts.com/cars/nissan/sentra/2023) - [2022](https://whichcarparts.com/cars/nissan/sentra/2022) - [2021](https://whichcarparts.com/cars/nissan/sentra/2021) - [2020](https://whichcarparts.com/cars/nissan/sentra/2020) - [2019](https://whichcarparts.com/cars/nissan/sentra/2019) - [2018](https://whichcarparts.com/cars/nissan/sentra/2018) - [2017](https://whichcarparts.com/cars/nissan/sentra/2017) - [2016](https://whichcarparts.com/cars/nissan/sentra/2016) - [2015](https://whichcarparts.com/cars/nissan/sentra/2015) - [2014](https://whichcarparts.com/cars/nissan/sentra/2014) - [2013](https://whichcarparts.com/cars/nissan/sentra/2013) - [2012](https://whichcarparts.com/cars/nissan/sentra/2012) More Nissan Sentra guides: - [Oil & filter](https://whichcarparts.com/cars/nissan/sentra/oil) - [Battery](https://whichcarparts.com/cars/nissan/sentra/battery) - [Tires & wheels](https://whichcarparts.com/cars/nissan/sentra/tires) - [Wiper blades](https://whichcarparts.com/cars/nissan/sentra/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/nissan/sentra/filters) - [Bulbs](https://whichcarparts.com/cars/nissan/sentra/bulbs) - [Brakes](https://whichcarparts.com/cars/nissan/sentra/brakes) - [Fluids](https://whichcarparts.com/cars/nissan/sentra/fluids) - [Service schedule](https://whichcarparts.com/cars/nissan/sentra/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/nissan/sentra/common-problems) - [Oil light reset](https://whichcarparts.com/cars/nissan/sentra/oil-reset) - [Specs](https://whichcarparts.com/cars/nissan/sentra/specs) Specifications vary with engine option, production date, and market.
