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

  1. 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.
  2. 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).
  3. 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.
  4. Insert the new cell with + and − matching the markings, then test lock and unlock before closing up.

Hyundai key fob help

Coin cells are dangerous if swallowed. Keep new and used batteries away from children. Energizer warns that swallowing can cause serious injury or death in as little as 2 hours; if a battery may have been swallowed, get medical help immediately (US National Battery Ingestion Hotline 800-498-8666, as listed by Energizer).
