Mazda key fob battery
We have not checked Mazda’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 5 models across the 2019 and 2025 model years; the cells that come up are CR2025, CR2032. Your own manual is the authority.

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”.
- Panasonic’s finder lists a model called “3” under Mazda, but the result page it returns is titled “Tesla 3”, so we left out: 2019 Mazda3 and 2025 Mazda3.
- Step-by-step replacement is in the owner’s manual; we don’t reproduce it here.
How we read the sources: method. All makes: key fob battery by make.
