Before you swap it
- CR2430 is the same 24.5 mm width as a CR2450 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.
- Note which way up the old cell sits before you take it out. Fitted upside down, the key won't work at all.
