A single CR2032 coin cell. ### Can you use a CR2032 instead of a CR2025 in a Honda CR-V 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 CR-V 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 - [NHTSA Part 573 report, 24V-744 steering gearbox ('sticky steering') recall](https://static.nhtsa.gov/odi/rcl/2024/RCLRPT-24V744-4093.PDF) - [NHTSA Part 573 report, 24V-763 high-pressure fuel pump recall](https://static.nhtsa.gov/odi/rcl/2024/RCLRPT-24V763-9335.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) - [Car and Driver, Honda recalls 720K Accord/Civic/CR-V over fuel pump](https://www.caranddriver.com/news/a62693114/honda-accord-civic-crv-fuel-pump-recall/) - [College Hills Honda, 2023-2027 CR-V maintenance parts (80291-TF3-E01, 17220-64A-A00)](https://www.collegehillshonda.com/category/6thgen-honda-crv-maintenance.html) - [Honda OEM Parts Online, 17220-6MA-J01 hybrid air filter (2023-2026)](https://honda.oempartsonline.com/oem-parts/honda-air-filter-172206maj01) - [AMSOIL lookup, 2023 CR-V 2.0L LFC3 oil capacity 4.2 qt](https://www.amsoil.com/lookup/auto-and-light-truck/2023/honda/cr-v/2-0l-4-cyl-engine-code-lfc3-8/) - [TireSize.com, 2023 CR-V OE fitments by trim](https://tiresize.com/tires/Honda/CR-V/2023/) - [AutoZone, 2024 CR-V battery (Group 47/H5)](https://www.autozone.com/batteries-starting-and-charging/battery/honda/cr-v/2024) - [HondaPartsNow, 2024 CR-V Hybrid OEM 12V battery (Group 51, 500 CCA)](https://www.hondapartsnow.com/oem-2024-honda-cr_v_hybrid-car_batteries.html) - [fueleconomy.gov, 2024 CR-V / CR-V Hybrid EPA ratings](https://www.fueleconomy.gov/feg/bymodel/2024_Honda_CR-V.shtml) - [WiperSizeChart, 2023/2024 CR-V wiper sizes 24/19/10](https://www.wipersizechart.com/make/honda/cr-v/2023) ## Find your exact CR-V - [2025](https://whichcarparts.com/cars/honda/cr-v/2025) - [2024](https://whichcarparts.com/cars/honda/cr-v/2024) - [2023](https://whichcarparts.com/cars/honda/cr-v/2023) - [2022](https://whichcarparts.com/cars/honda/cr-v/2022) - [2021](https://whichcarparts.com/cars/honda/cr-v/2021) - [2020](https://whichcarparts.com/cars/honda/cr-v/2020) - [2019](https://whichcarparts.com/cars/honda/cr-v/2019) - [2018](https://whichcarparts.com/cars/honda/cr-v/2018) - [2017](https://whichcarparts.com/cars/honda/cr-v/2017) - [2016](https://whichcarparts.com/cars/honda/cr-v/2016) - [2015](https://whichcarparts.com/cars/honda/cr-v/2015) - [2014](https://whichcarparts.com/cars/honda/cr-v/2014) - [2013](https://whichcarparts.com/cars/honda/cr-v/2013) - [2012](https://whichcarparts.com/cars/honda/cr-v/2012) More Honda CR-V guides: - [Oil & filter](https://whichcarparts.com/cars/honda/cr-v/oil) - [Battery](https://whichcarparts.com/cars/honda/cr-v/battery) - [Tires & wheels](https://whichcarparts.com/cars/honda/cr-v/tires) - [Wiper blades](https://whichcarparts.com/cars/honda/cr-v/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/honda/cr-v/filters) - [Bulbs](https://whichcarparts.com/cars/honda/cr-v/bulbs) - [Brakes](https://whichcarparts.com/cars/honda/cr-v/brakes) - [Fluids](https://whichcarparts.com/cars/honda/cr-v/fluids) - [Service schedule](https://whichcarparts.com/cars/honda/cr-v/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/honda/cr-v/common-problems) - [Oil light reset](https://whichcarparts.com/cars/honda/cr-v/oil-reset) - [Specs](https://whichcarparts.com/cars/honda/cr-v/specs) Specifications vary with engine option, production date, and market.
