Peugeot 107 key fob battery (2005–2014): CR2016

The Peugeot 107 key fob (2005–2014) takes one CR2016 3V lithium coin cell.

Before you swap it

• A CR2016 is 1.6 mm thick. CR2025 and CR2032 look the same from the front, but they aren't the same cell, and a thinner one can rattle or lose contact.
• 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.
