Source: Energizer Key Fob Battery Replacement Guide (©2023, model years 2014–2023), PDF checked 12 November 2026. “—” means the source lists no battery for that year and key type; it does not mean the vehicle has no fob.
How to confirm before you buy
- Open the fob and read the code printed on the old coin cell (e.g. “CR2032”). That printed code beats any chart, including this one.
- Check which kind of fob you have. Many models list a different battery for a smart key (push-button start / keyless entry) than for a remote key (flip or blade key with buttons).
- Match the code exactly. CR2025 and CR2032 have the same diameter but different thickness, so the wrong one can fit loosely or force the case open.
- Insert the new cell with + and − matching the markings, then test lock and unlock before closing up.
