Key fob battery size by make and model

GarageDex lists which coin cell your remote or smart key takes - CR2032, CR2025, CR2450 and the rest - for 60 models across 13 makes, by year range. Pick your make.

Key takeaways

  • Most fobs take a CR2032, but CR2025 and CR2016 are the same width and thinner - a thinner cell rattles and loses contact.
  • Match the code printed on the old cell; the number is the size (20 mm wide, 3.2 mm thick for a CR2032).
  • Note which side faces up before you pull the old cell - orientation matters.
  • A dying fob battery usually shows up as shorter range first, then a dash warning.
