A single CR2032 coin cell. ### Can you use a CR2032 instead of a CR2025 in a Honda Civic key fob? This fob takes a CR2032, 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 Honda Civic 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 - [Honda techinfo, 2025 Civic Sedan Hybrid owner's manual specifications (oil 0W-20, 4.2 qt with filter)](https://techinfo.honda.com/rjanisis/pubs/OM/AH/AT542525IOM/enu/details/131266047-16992.html) - [AMSOIL product application guide, 2025 Civic Type R 2.0L K20C1 (5.7 qt with filter)](https://www.amsoil.com/lookup/auto-and-light-truck/2025/honda/civic/2-0l-4-cyl-engine-code-k20c1-2-turbo/) - [NHTSA recall 24V-744, steering gearbox worm wheel ('sticky steering')](https://static.nhtsa.gov/odi/rcl/2024/RCLRPT-24V744-4093.PDF) - [Honda News, American Honda recalls ~1.7M vehicles to repair steering gearboxes](https://hondanews.com/en-US/releases/american-honda-recalls-approximately-17-million-vehicles-to-repair-steering-gearboxes) - [Honda News, 2025 Civic Sedan specifications (fuel tank, curb weight)](https://hondanews.com/en-US/honda-automobiles/releases/release-c28e8d1efb94e520fef21ff3f800cb30-2025-honda-civic-sedan-specifications-features) - [fueleconomy.gov, 2025 Honda Civic EPA ratings (incl. hybrid)](https://www.fueleconomy.gov/feg/bymodel/2025_Honda_Civic.shtml) - [Honda parts, 76620-T20-A01 wiper blade, 2022-2025 Civic](https://honda.oempartsonline.com/oem-parts/honda-wiper-blade-76620t20a01) - [Honda parts, 17220-5BA-A00 air filter (2016-2026, 2.0L non-turbo)](https://honda.oempartsonline.com/oem-parts/honda-air-filter-172205baa00) - [TireSize.com, 2023 Honda Civic OE tire sizes by trim](https://tiresize.com/tires/Honda/Civic/2023/) - [Civic11 forum, Touring sedan door-placard pressures (33/32)](https://www.civic11forum.com/threads/psa-check-your-tire-pressure.802/) - [Honda techinfo, 2022 Civic Maintenance Minder usage](https://techinfo.honda.com/rjanisis/pubs/OM/AH/AT202222IOM/enu/details/131229047-12935.html) ## Find your exact Civic - [2025](https://whichcarparts.com/cars/honda/civic/2025) - [2024](https://whichcarparts.com/cars/honda/civic/2024) - [2023](https://whichcarparts.com/cars/honda/civic/2023) - [2022](https://whichcarparts.com/cars/honda/civic/2022) - [2021](https://whichcarparts.com/cars/honda/civic/2021) - [2020](https://whichcarparts.com/cars/honda/civic/2020) - [2019](https://whichcarparts.com/cars/honda/civic/2019) - [2018](https://whichcarparts.com/cars/honda/civic/2018) - [2017](https://whichcarparts.com/cars/honda/civic/2017) - [2016](https://whichcarparts.com/cars/honda/civic/2016) - [2015](https://whichcarparts.com/cars/honda/civic/2015) - [2014](https://whichcarparts.com/cars/honda/civic/2014) - [2013](https://whichcarparts.com/cars/honda/civic/2013) - [2012](https://whichcarparts.com/cars/honda/civic/2012) More Honda Civic guides: - [Oil & filter](https://whichcarparts.com/cars/honda/civic/oil) - [Battery](https://whichcarparts.com/cars/honda/civic/battery) - [Tires & wheels](https://whichcarparts.com/cars/honda/civic/tires) - [Wiper blades](https://whichcarparts.com/cars/honda/civic/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/honda/civic/filters) - [Bulbs](https://whichcarparts.com/cars/honda/civic/bulbs) - [Brakes](https://whichcarparts.com/cars/honda/civic/brakes) - [Fluids](https://whichcarparts.com/cars/honda/civic/fluids) - [Service schedule](https://whichcarparts.com/cars/honda/civic/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/honda/civic/common-problems) - [Oil light reset](https://whichcarparts.com/cars/honda/civic/oil-reset) - [Specs](https://whichcarparts.com/cars/honda/civic/specs) Specifications vary with engine option, production date, and market.
