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.
- Keep the old cell until the new one works. If the car still won't respond, the new cell is usually in the wrong way up.
