How to open the fob without breaking it, and which substitutions actually work. **Quick answer**: The 2020-2025 Toyota Highlander key fob takes a CR2032 coin-cell battery, available at any pharmacy, hardware store, or online for a few dollars. ## Replacing the 2020-2025 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 2020 through 2025, the XU70 (4th generation), mid-size 3-row crossover suv (tnga-k platform). Nothing in this specification changes between those model years. - [2020 Highlander](https://whichcarparts.com/cars/toyota/highlander/2020) - [2021 Highlander](https://whichcarparts.com/cars/toyota/highlander/2021) - [2022 Highlander](https://whichcarparts.com/cars/toyota/highlander/2022) - [2023 Highlander](https://whichcarparts.com/cars/toyota/highlander/2023) - [2024 Highlander](https://whichcarparts.com/cars/toyota/highlander/2024) - [2025 Highlander](https://whichcarparts.com/cars/toyota/highlander/2025) ## What changed during the 2020-2025 Toyota Highlander | Years | What changed | | --- | --- | | 2020 | Generation launch on TNGA-K.

A single CR2032 coin cell. ### Can you use a CR2032 instead of a CR2025 in a 2020-2025 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 2020-2025 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 XU70 fluids & capacities (toyota-club.net)](https://toyota-club.net/files/techdata/ttx/highlander_70u.htm) - [Toyota Owners, 2021 Highlander Hybrid owner's manual, 12-volt battery location](https://www.toyota.com/owners/warranty-owners-manuals/digital/article/highlander-hv/2021/om0e143u/ch06se030405/) - [Toyota TrueStart battery application chart, H6 EFB (gas) / H5 LN2 (hybrid)](https://www.toyotapartsandservice.com/wp-content/uploads/2022/11/03_Batteries2022_hi.pdf) - [Lakeland Toyota parts, 17801-F0050 engine air filter, 2021/2023 Highlander fitment](https://parts.lakelandtoyota.com/p/toyota_2023_HIGHLANDER/Engine-Air-Filter/14760743/17801F0050.html) - [Woburn Toyota parts, 04152-YZZA1 oil filter element fitment for the 2.4L turbo](https://parts.woburntoyota.com/p/Toyota_2025_GRAND-HIGHLANDER-24L-AT-AWD-Limited-Sport-Utility/Engine-Oil-Filter-Element/49507508/04152YZZA1.html) - [Lakeland Toyota parts, 90919-A1008 spark plug (2.4L turbo)](https://toyotaparts.lakelandtoyota.com/oem-parts/toyota-spark-plug-90919a1008) - [AMSOIL lookup, 2023 Highlander 2.4L T24A-FTS: 0W-20, 5.6 qt](https://www.amsoil.com/lookup/auto-and-light-truck/2023/toyota/highlander/2-4l-4-cyl-engine-code-t24a-fts-g-turbo/) - [NHTSA recall 23V-865, occupant classification sensor](https://www.nhtsa.gov/recalls?nhtsaId=23V865000) - [NHTSA recall 25V-595, instrument cluster display](https://www.nhtsa.gov/recalls?nhtsaId=25V595000) - [ClassAction.org, 2020-2021 Highlander Hybrid fuel tank fill issue](https://www.classaction.org/news/venting-issue-prevents-2020-2021-toyota-highlander-hybrid-fuel-tank-from-being-filled-to-capacity-class-action-claims) - [The Weekly Driver, 2020-2025 Highlander NHTSA complaint analysis (transmission cluster)](https://theweeklydriver.com/reliability/toyota/highlander/2020-2025/) - [Wheel-Size.com, 2023 Toyota Highlander OE fitments](https://www.wheel-size.com/size/toyota/highlander/2023/) - [fueleconomy.gov, 2021 / 2023 Highlander EPA ratings](https://www.fueleconomy.gov/feg/bymodel/2023_Toyota_Highlander.shtml) ## Other Toyota Highlander generations - [2014-2019 Toyota Highlander key fob battery](https://whichcarparts.com/cars/toyota/highlander/2014-2019/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 2020-2025 Toyota Highlander - [Oil & filter](https://whichcarparts.com/cars/toyota/highlander/2020-2025/oil) - [Battery](https://whichcarparts.com/cars/toyota/highlander/2020-2025/battery) - [Tires & wheels](https://whichcarparts.com/cars/toyota/highlander/2020-2025/tires) - [Wiper blades](https://whichcarparts.com/cars/toyota/highlander/2020-2025/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/toyota/highlander/2020-2025/filters) - [Bulbs](https://whichcarparts.com/cars/toyota/highlander/2020-2025/bulbs) - [Brakes](https://whichcarparts.com/cars/toyota/highlander/2020-2025/brakes) - [Fluids](https://whichcarparts.com/cars/toyota/highlander/2020-2025/fluids) - [Service schedule](https://whichcarparts.com/cars/toyota/highlander/2020-2025/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/toyota/highlander/2020-2025/common-problems) - [Oil light reset](https://whichcarparts.com/cars/toyota/highlander/2020-2025/oil-reset) - [Specs](https://whichcarparts.com/cars/toyota/highlander/2020-2025/specs) Specifications vary with engine option, production date, and market.
