You can't & you don't have to. The inner & outer door panels are bonded together with foam & can't be seperated without stuffing up the whole door. The door handle is held on with a retaining plate & one screw at the edge of the door. The other end of the handle is curved & is slipped in to the hole on the door before putting the retainer & screw back on the other end.
