We start the opening process at the connector side. It consists of 2 parts: the top which is made from plastic and the bottom which is made from aluminium. They are hold in position by pins (so don't use a lot of force when you feel a resistance) and glued together.

Heat it up and gently cut between the top and the alcantara. Watch out not to tilt your opening tool, otherwise you will likely cause permanent damage on the alcantara. Keep it open with the opening picks and work your way along the top until it pops up.
