if you dont have access to the information then, firstly find a flat and stiff two prong fork shaped item (nylon type preferred) and a long piece of card (business card thickness)
slide the business card between the metal and plastic panel to "feel" the plastic pins. Once you feel them, pop it with the tool. proceed to the next and pop out each one.
The handle is usually screwed into the door and so is the door pull - it may have a cover on it. the upper edge of it always pulls upwards, but assist it with some tool from the window ledge (dont break the glass) - gently lift off the panel, undo the cables/rods, electrics etc.
