Before you swap it

  • CR2016 and CR2025 are the same 20 mm width as a CR2032 but a different thickness, so read the code on the old cell before you order, because a cell that's too thin can lose contact every time the fob gets knocked.
  • Car still ignoring the fob after a new cell? Check it went in the right way up. The + side usually faces the marking inside the case.
