Peugeot 207 key fob battery (2006–2012): CR1620

The Peugeot 207 key fob (2006–2012) 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.
• 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.
