Subaru key fob battery
The coin cell for each Subaru key below is read from Subaru’s own owner’s manual for that model year, with the PDF page it’s on. We checked 3 models across the 2019 and 2025 model years; the cells that come up are CR1620, CR2025, CR2032.
Where the cell changed between model years
Crosstrek transmitter: CR1620 for 2019, CR2025 for 2025. Check the year on your own manual before you swap the cell.
Forester transmitter: CR1620 for 2019, CR2025 for 2025. Check the year on your own manual before you swap the cell.
Outback transmitter: CR1620 for 2019, CR2025 for 2025. Check the year on your own manual before you swap the cell.

- 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 manual’s own name for it.
- Step-by-step replacement is in the owner’s manual page cited on each row; we don’t reproduce it here.
