Model: Citroen C3 Picasso MK 1 - Years 2008-2017
Part: Key

In this video tutorial, you will learn how to dismantle and replace the battery in the key for various Citroen models, particularly the C2 and C3 Picasso. First, take your remote and use a screwdriver to unscrew the key screw, removing it. Then, open the remote into two parts by inserting a lever into the designated hole and remove the electronic part along with the battery. Replace it with a new one of the correct type (usually a 2032) and insert it in the correct orientation. Then, reassemble the two halves of the remote and insert the key, finally putting the screw back in!
