Citroën C3 Picasso key fob battery (2009–2017): CR1620

The Citroën C3 Picasso key fob (2009–2017) takes one CR1620 3V lithium coin cell.

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.
• Note which way up the old cell sits before you take it out. Fitted upside down, the key won't work at all.
