How to open the fob without breaking it, and which substitutions actually work. **Quick answer**: The 2014-2019 Toyota Highlander key fob takes a CR2032 coin-cell battery, available at any pharmacy, hardware store, or online for a few dollars. ## Replacing the 2014-2019 Toyota Highlander 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 Toyota Highlander model years does this cover? These key fob battery specifications apply to every Toyota Highlander built from 2014 through 2019, the XU50 (3rd generation), mid-size 3-row crossover suv.

A single CR2032 coin cell. ### Can you use a CR2032 instead of a CR2025 in a 2014-2019 Toyota Highlander 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 2014-2019 Toyota Highlander 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 - [Toyota technical data, Highlander XU50 fluids & capacities (toyota-club.net)](https://toyota-club.net/files/techdata/ttx/highlander_50u.htm) - [Toyota OEM parts, 17801-0P090 engine air filter fitment (2017-2019 incl. hybrid)](https://toyota.oempartsonline.com/oem-parts/toyota-air-filter-178010p090) - [Toyota Genuine spark plug application chart (toyotapartsandservice.com)](https://www.toyotapartsandservice.com/wp-content/uploads/2022/11/09_SparkPlugs2022_hi.pdf) - [Toyota TrueStart battery application chart, 24F / 24F EFB stop-start](https://www.toyotapartsandservice.com/wp-content/uploads/2022/11/03_Batteries2022_hi.pdf) - [NHTSA recall 20V-682, Denso fuel pump (2017-2019 Highlander)](https://www.nhtsa.gov/recalls?nhtsaId=20V682000) - [ToyotaNation, T-SB-0160-18 UA80F transmission TSB discussion](https://www.toyotanation.com/threads/did-toyota-really-fix-the-transmission-issue-for-2019.1722708/) - [O'Reilly How-To, reset maintenance light, 2014-2019 Highlander](https://www.oreillyauto.com/how-to-hub/how-to-reset-the-maintenance-light-in-a-2014-to-2019-toyota-highlander) - [Wheel-Size.com, 2016 Toyota Highlander OE fitments](https://www.wheel-size.com/size/toyota/highlander/2016/) - [fueleconomy.gov, 2016 / 2018 Highlander EPA ratings](https://www.fueleconomy.gov/feg/bymodel/2018_Toyota_Highlander.shtml) ## Other Toyota Highlander generations - [2020-2025 Toyota Highlander key fob battery](https://whichcarparts.com/cars/toyota/highlander/2020-2025/key-fob-battery) - [2012-2013 Toyota Highlander key fob battery](https://whichcarparts.com/cars/toyota/highlander/2012-2013/key-fob-battery) Or [compare all generations](https://whichcarparts.com/cars/toyota/highlander/key-fob-battery). ## More for the 2014-2019 Toyota Highlander - [Oil & filter](https://whichcarparts.com/cars/toyota/highlander/2014-2019/oil) - [Battery](https://whichcarparts.com/cars/toyota/highlander/2014-2019/battery) - [Tires & wheels](https://whichcarparts.com/cars/toyota/highlander/2014-2019/tires) - [Wiper blades](https://whichcarparts.com/cars/toyota/highlander/2014-2019/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/toyota/highlander/2014-2019/filters) - [Bulbs](https://whichcarparts.com/cars/toyota/highlander/2014-2019/bulbs) - [Brakes](https://whichcarparts.com/cars/toyota/highlander/2014-2019/brakes) - [Fluids](https://whichcarparts.com/cars/toyota/highlander/2014-2019/fluids) - [Service schedule](https://whichcarparts.com/cars/toyota/highlander/2014-2019/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/toyota/highlander/2014-2019/common-problems) - [Oil light reset](https://whichcarparts.com/cars/toyota/highlander/2014-2019/oil-reset) - [Specs](https://whichcarparts.com/cars/toyota/highlander/2014-2019/specs) Specifications vary with engine option, production date, and market.
