How to open the fob without breaking it, and which substitutions actually work. **Quick answer**: The 2018-2022 Honda Accord key fob takes a CR2032 coin-cell battery, available at any pharmacy, hardware store, or online for a few dollars. ## Replacing the 2018-2022 Honda Accord 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 Honda Accord model years does this cover? These key fob battery specifications apply to every Honda Accord built from 2018 through 2022, the 10th generation, mid-size sedan (fastback roofline; coupe discontinued). Nothing in this specification changes between those model years. - [2018 Accord](https://whichcarparts.com/cars/honda/accord/2018) - [2019 Accord](https://whichcarparts.com/cars/honda/accord/2019) - [2020 Accord](https://whichcarparts.com/cars/honda/accord/2020) - [2021 Accord](https://whichcarparts.com/cars/honda/accord/2021) - [2022 Accord](https://whichcarparts.com/cars/honda/accord/2022) ## What changed during the 2018-2022 Honda Accord | Years | What changed | | --- | --- | | 2018 | Generation launch: turbo-only lineup, LED low beams standard, V6 and coupe dropped | | 2021 | Facelift: revised front end, Sport SE trim, hybrid gains steering-wheel deceleration paddles; manual transmission dropped after 2020 | | 2022 | Final year for the 2.0T and 10-speed in the Accord | ## 2018-2022 Honda Accord key fob battery: common questions ### What battery does the 2018-2022 Honda Accord key fob take? A single CR2032 coin cell. ### Can you use a CR2032 instead of a CR2025 in a 2018-2022 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 2018-2022 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 - [AutoZone fitment, 2018 Accord H5 (1.5T) / H6 (2.0T) batteries](https://www.autozone.com/batteries-starting-and-charging/battery/honda/accord/2018) - [Honda Info Center, 2022 Accord wheels and tires by trim](https://www.hondainfocenter.com/2022/Accord/Feature-Guide/Exterior-Features/Wheels-and-Tires/) - [AMSOIL lookup, 2022 Accord 1.5L L15BE oil capacity](https://www.amsoil.com/lookup/auto-and-light-truck/2022/honda/accord/1-5l-4-cyl-engine-code-l15be-8-turbo/) - [AMSOIL lookup, 2018 Accord 2.0L K20C4 oil capacity](https://www.amsoil.com/lookup/auto-and-light-truck/2018/honda/accord/2-0l-4-cyl-engine-code-k20c4-7-turbo/) - [NHTSA recall 20V-314, Denso fuel pump (Honda)](https://static.nhtsa.gov/odi/rcl/2020/RCLRPT-20V314-8555.PDF) - [Honda News, fuel pump recall statement listing 2018-2020 Accord](https://hondanews.com/en-US/honda-corporate/releases/release-a463299e9046a088b84018a75800469c-statement-by-american-honda-regarding-fuel-pump-recall-2017-2020-acura-and-honda-models) - [oemdtc, 2018-2020 Accord A/C condenser warranty extension bulletin](https://honda.oemdtc.com/1687/warranty-extension-2018-2020-honda-accord-a-c-condenser/) - [Honda parts, 17220-6A0-A00 (1.5T) air filter fitment](https://honda.oempartsonline.com/oem-parts/honda-air-filter-172206a0a00) - [Honda parts, spark plug 12290-6A0-A01 (1.5T/2.0T)](https://honda.oempartsonline.com/oem-parts/honda-spark-plug-122906a0a01) - [DriveAccord, 10th-gen hybrid spark plug 12290-6C1-A01 (NGK DILZKAR7D11S)](https://www.driveaccord.net/threads/2018-2022-accord-hybrid-spark-plug-replacement-ngk-dilzkar7d11s-or-bosch-96328.568347/) - [Wards Auto, Honda 1.5L oil dilution warranty extension](https://www.wardsauto.com/news/archive-wards-honda-extends-warranty-to-address-1-5l-gas-oil-dilution-problem/793295/) - [Honda Owners, 2022 Accord Maintenance Minder guide (reset procedure)](https://owners.honda.com/utility/download?path=/static/pdfs/2022/Accord%20Sedan/2022_Accord_4D_Maintenance_Minder.pdf) ## Other Honda Accord generations - [2023-2025 Honda Accord key fob battery](https://whichcarparts.com/cars/honda/accord/2023-2025/key-fob-battery) - [2013-2017 Honda Accord key fob battery](https://whichcarparts.com/cars/honda/accord/2013-2017/key-fob-battery) Or [compare all generations](https://whichcarparts.com/cars/honda/accord/key-fob-battery). ## More for the 2018-2022 Honda Accord - [Oil & filter](https://whichcarparts.com/cars/honda/accord/2018-2022/oil) - [Battery](https://whichcarparts.com/cars/honda/accord/2018-2022/battery) - [Tires & wheels](https://whichcarparts.com/cars/honda/accord/2018-2022/tires) - [Wiper blades](https://whichcarparts.com/cars/honda/accord/2018-2022/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/honda/accord/2018-2022/filters) - [Bulbs](https://whichcarparts.com/cars/honda/accord/2018-2022/bulbs) - [Brakes](https://whichcarparts.com/cars/honda/accord/2018-2022/brakes) - [Fluids](https://whichcarparts.com/cars/honda/accord/2018-2022/fluids) - [Service schedule](https://whichcarparts.com/cars/honda/accord/2018-2022/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/honda/accord/2018-2022/common-problems) - [Oil light reset](https://whichcarparts.com/cars/honda/accord/2018-2022/oil-reset) - [Specs](https://whichcarparts.com/cars/honda/accord/2018-2022/specs) Specifications vary with engine option, production date, and market.
