Before you swap it
- CR1632 is the same 16 mm width as a CR1620 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.
