We found no public copy of Toyota’s owner’s manuals for these model years, so every row below comes
from one source only: Panasonic’s key fob battery finder, with the finder entry named on the row.
We checked 4 models across the 2019 and 2025 model years; the cells that come up are CR2016, CR2032, CR2450.
Your own manual is the authority.
Camry key: CR2032 for 2019,
CR2450 for 2025. Check the year on your own manual before you swap the cell.
Corolla smart key: CR2032 for 2019,
CR2450 for 2025. Check the year on your own manual before you swap the cell.
Corolla wireless remote: CR2016 for 2019,
CR2032 for 2025. Check the year on your own manual before you swap the cell.
Tacoma smart key: CR2032 for 2019,
CR2450 for 2025. Check the year on your own manual before you swap the cell.

What this page doesn’t cover
Only the model years listed. Other years may use a different cell; the manual for your year is the authority.
Trim levels can come with different keys. The key type named in each row is the finder’s own name for it; where the finder names none, the row just says “Key”.
We found no public source that names the cell for: 2018 RAV4, 2024 Corolla and 2024 Tacoma.
Step-by-step replacement is in the owner’s manual; we don’t reproduce it here.
