Peugeot Expert key fob battery (2007–2016): CR1620

The Peugeot Expert key fob (2007–2016) takes one CR1620 3V lithium coin cell.

Before you swap it

• A CR1620 is 2 mm thick. CR1632 looks the same from the front, but it isn't the same cell, and a thinner one can rattle or lose contact.
• Note which way up the old cell sits before you take it out. Fitted upside down, the key won't work at all.
