How to open the fob without breaking it, and which substitutions actually work. **Quick answer**: The 2013-2017 Honda Accord key fob takes a CR2032 (smart key and remote-head key) coin-cell battery, available at any pharmacy, hardware store, or online for a few dollars. ## Replacing the 2013-2017 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 2013 through 2017, the 9th generation, mid-size sedan and coupe. Nothing in this specification changes between those model years. - [2013 Accord](https://whichcarparts.com/cars/honda/accord/2013) - [2014 Accord](https://whichcarparts.com/cars/honda/accord/2014) - [2015 Accord](https://whichcarparts.com/cars/honda/accord/2015) - [2016 Accord](https://whichcarparts.com/cars/honda/accord/2016) - [2017 Accord](https://whichcarparts.com/cars/honda/accord/2017) ## What changed during the 2013-2017 Honda Accord | Years | What changed | | --- | --- | | 2013 | Generation launch; Earth Dreams engines, CVT replaces the old 5AT on 4-cylinders | | 2014 | Accord Hybrid (196 hp i-MMD) and Accord Plug-In launch; Plug-In sold in limited states for 2014 only | | 2016-2017 | Facelift: new fascias, Honda Sensing widely available, Sport/Touring move to 19-in wheels, electronic parking brake, LED headlights on upper trims.

A single CR2032 (smart key and remote-head key) coin cell. ### Can you use a CR2032 instead of a CR2025 in a 2013-2017 Honda Accord key fob? This fob takes a CR2032 (smart key and remote-head 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 2013-2017 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, 2015 Accord Group 51R battery](https://www.autozone.com/batteries-starting-and-charging/battery/honda/accord/2015) - [Goodyear fitment, 2013 Accord tire sizes by trim](https://www.goodyear.com/en-us/vehicles/Honda/Accord/2013) - [AMSOIL lookup, 2013 Accord 2.4L K24W1 oil capacity](https://www.amsoil.com/lookup/auto-and-light-truck/2013/honda/accord/2-4l-4-cyl-engine-code-k24w1-k/) - [AMSOIL lookup, 2013 Accord 3.5L J35Y1 oil capacity](https://www.amsoil.com/lookup/auto-and-light-truck/2013/honda/accord/3-5l-6-cyl-engine-code-j35y1-j/) - [CarComplaints, 2014 Accord TSB index (CVT judder A17-017, starter A16-002, VTC, EPS A15-056)](https://www.carcomplaints.com/Honda/Accord/2014/tsbs/) - [CarComplaints, Accord/Crosstour starter motor lawsuit (TSB A16-002)](https://m.carcomplaints.com/news/2017/honda-accord-crosstour-starter-motor-lawsuit.shtml) - [Honda parts catalog, 17220-5A2-A00 air filter (2.4L)](https://www.hondapartsnow.com/oem-honda-accord-air_filter.html) - [Honda parts, spark plug 12290-R71-L01 (NGK DILZKR7A11G)](https://www.hondapartsguys.com/oem-parts/honda-2008-2017-honda-spark-plug-dilzkr7a11g-ngk-12290r71l01) - [Oil filter cross-reference, Honda 15400-PLM-A02 equivalents](https://www.oilfilter-crossreference.com/convert/HONDA/15400-PLM-A02) ## Other Honda Accord generations - [2023-2025 Honda Accord key fob battery](https://whichcarparts.com/cars/honda/accord/2023-2025/key-fob-battery) - [2018-2022 Honda Accord key fob battery](https://whichcarparts.com/cars/honda/accord/2018-2022/key-fob-battery) Or [compare all generations](https://whichcarparts.com/cars/honda/accord/key-fob-battery). ## More for the 2013-2017 Honda Accord - [Oil & filter](https://whichcarparts.com/cars/honda/accord/2013-2017/oil) - [Battery](https://whichcarparts.com/cars/honda/accord/2013-2017/battery) - [Tires & wheels](https://whichcarparts.com/cars/honda/accord/2013-2017/tires) - [Wiper blades](https://whichcarparts.com/cars/honda/accord/2013-2017/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/honda/accord/2013-2017/filters) - [Bulbs](https://whichcarparts.com/cars/honda/accord/2013-2017/bulbs) - [Brakes](https://whichcarparts.com/cars/honda/accord/2013-2017/brakes) - [Fluids](https://whichcarparts.com/cars/honda/accord/2013-2017/fluids) - [Service schedule](https://whichcarparts.com/cars/honda/accord/2013-2017/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/honda/accord/2013-2017/common-problems) - [Oil light reset](https://whichcarparts.com/cars/honda/accord/2013-2017/oil-reset) - [Specs](https://whichcarparts.com/cars/honda/accord/2013-2017/specs) Specifications vary with engine option, production date, and market.
