A single CR2032 coin cell. ### Can you use a CR2032 instead of a CR2025 in a Honda Accord 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 Accord 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 - [Goodyear fitment, 2024 Accord tire sizes by trim](https://www.goodyear.com/en-us/vehicles/Honda/Accord/2024) - [Honda News, 2023 Accord specifications & features](https://hondanews.com/en-US/honda-automobiles/releases/release-4e58b4e0fcd795affa5685a66a387e28-2023-honda-accord-specifications-features) - [College Hills Honda, 2023-2026 Accord maintenance parts (filters, 15400-PLM-A02)](https://www.collegehillshonda.com/category/11thgen-honda-accord-maintenance-parts.html) - [NHTSA recall 23V-782, seat belt pretensioner (2023-2024 Accord/HR-V)](https://static.nhtsa.gov/odi/rcl/2023/RCLRPT-23V782-1271.PDF) - [Wards Auto, Honda recalls ~257K Accord Hybrids for ICM software (25V-785)](https://www.wardsauto.com/news/honda-recalls-257K-accord-hybrids-software-error-nhtsa/807113/) - [Honda News, 2023-2024 Accord and HR-V seat belt pretensioner recall](https://hondanews.com/en-US/honda-corporate/releases/release-ce25b2bdc6167d48c9de61f4f905d5be-2023-2024-accord-and-hr-v-seat-belt-pretensioner-recall) - [Advance Auto Parts, 2023 Accord H5 battery fitments](https://shop.advanceautoparts.com/find/2023-honda-accord-batteries) - [EngineOilDB, 2023/2024 Accord oil capacities (1.5T 3.7 qt, hybrid 4.2 qt)](https://engineoildb.com/oil-info/2023-honda-accord/) ## Find your exact Accord - [2025](https://whichcarparts.com/cars/honda/accord/2025) - [2024](https://whichcarparts.com/cars/honda/accord/2024) - [2023](https://whichcarparts.com/cars/honda/accord/2023) - [2022](https://whichcarparts.com/cars/honda/accord/2022) - [2021](https://whichcarparts.com/cars/honda/accord/2021) - [2020](https://whichcarparts.com/cars/honda/accord/2020) - [2019](https://whichcarparts.com/cars/honda/accord/2019) - [2018](https://whichcarparts.com/cars/honda/accord/2018) - [2017](https://whichcarparts.com/cars/honda/accord/2017) - [2016](https://whichcarparts.com/cars/honda/accord/2016) - [2015](https://whichcarparts.com/cars/honda/accord/2015) - [2014](https://whichcarparts.com/cars/honda/accord/2014) - [2013](https://whichcarparts.com/cars/honda/accord/2013) More Honda Accord guides: - [Oil & filter](https://whichcarparts.com/cars/honda/accord/oil) - [Battery](https://whichcarparts.com/cars/honda/accord/battery) - [Tires & wheels](https://whichcarparts.com/cars/honda/accord/tires) - [Wiper blades](https://whichcarparts.com/cars/honda/accord/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/honda/accord/filters) - [Bulbs](https://whichcarparts.com/cars/honda/accord/bulbs) - [Brakes](https://whichcarparts.com/cars/honda/accord/brakes) - [Fluids](https://whichcarparts.com/cars/honda/accord/fluids) - [Service schedule](https://whichcarparts.com/cars/honda/accord/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/honda/accord/common-problems) - [Oil light reset](https://whichcarparts.com/cars/honda/accord/oil-reset) - [Specs](https://whichcarparts.com/cars/honda/accord/specs) Specifications vary with engine option, production date, and market.
