How to open the fob without breaking it, and which substitutions actually work. **Quick answer**: The 2012-2015 Toyota Tacoma key fob takes a CR2032 coin-cell battery, available at any pharmacy, hardware store, or online for a few dollars. ## Replacing the 2012-2015 Toyota Tacoma 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 Tacoma model years does this cover? These key fob battery specifications apply to every Toyota Tacoma built from 2012 through 2015, the 2nd generation (N250, facelift years), mid-size pickup (regular, access, double cab; 2wd/4wd).

A single CR2032 coin cell. ### Can you use a CR2032 instead of a CR2025 in a 2012-2015 Toyota Tacoma 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 2012-2015 Toyota Tacoma 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, Tacoma N200 fluids & capacities (toyota-club.net)](https://toyota-club.net/files/techdata/ttx/tacoma_200.htm) - [Toyota Support, which engines get 5,000 vs 10,000-mile oil intervals](https://support.toyota.com/s/article/What-are-the-oil-chan-7604) - [NHTSA recall 13V-557, 2TR-FE valve springs](https://static.nhtsa.gov/odi/rcl/2013/RCMN-13V557-5284.pdf) - [NHTSA TSB T-SB-0046-12, 4WD rear propeller shaft clunk](https://static.nhtsa.gov/odi/tsbs/2013/MC-10132101-9999.pdf) - [Reuters, Toyota $3.4B frame rust settlement (2005-2010 Tacoma)](https://www.reuters.com/article/business/toyota-to-settle-us-truck-rust-lawsuit-for-up-to-34-billion-idUSKBN1370PE/) - [TirePressures.co, 2013 Tacoma placard pressures](https://tirepressures.co/cars/toyota/tacoma/2013/) - [fueleconomy.gov, 2014 Tacoma EPA ratings](https://www.fueleconomy.gov/feg/bymodel/2014_Toyota_Tacoma.shtml) - [Kendall Toyota parts, 90915-YZZD1 oil filter supersession](https://parts.kendalltoyota.com/oem-parts/toyota-oil-filter-90915yzzd1) ## Other Toyota Tacoma generations - [2024-2025 Toyota Tacoma key fob battery](https://whichcarparts.com/cars/toyota/tacoma/2024-2025/key-fob-battery) - [2016-2023 Toyota Tacoma key fob battery](https://whichcarparts.com/cars/toyota/tacoma/2016-2023/key-fob-battery) Or [compare all generations](https://whichcarparts.com/cars/toyota/tacoma/key-fob-battery). ## More for the 2012-2015 Toyota Tacoma - [Oil & filter](https://whichcarparts.com/cars/toyota/tacoma/2012-2015/oil) - [Battery](https://whichcarparts.com/cars/toyota/tacoma/2012-2015/battery) - [Tires & wheels](https://whichcarparts.com/cars/toyota/tacoma/2012-2015/tires) - [Wiper blades](https://whichcarparts.com/cars/toyota/tacoma/2012-2015/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/toyota/tacoma/2012-2015/filters) - [Bulbs](https://whichcarparts.com/cars/toyota/tacoma/2012-2015/bulbs) - [Fluids](https://whichcarparts.com/cars/toyota/tacoma/2012-2015/fluids) - [Service schedule](https://whichcarparts.com/cars/toyota/tacoma/2012-2015/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/toyota/tacoma/2012-2015/common-problems) - [Oil light reset](https://whichcarparts.com/cars/toyota/tacoma/2012-2015/oil-reset) - [Specs](https://whichcarparts.com/cars/toyota/tacoma/2012-2015/specs) Specifications vary with engine option, production date, and market.
