First remove the handle cover of the door trim panel. Take out the screwdriver, as shown in the figure, and pry it from the edge gap between the door trim panel and the inner handle cover, and pry up the clips inside bit by bit, one clip and three clips. Be sure to pry it in the right position and pry it gently!
After prying off all three clips, hold the handle cover of the door trim panel by hand, gently pull it out and remove it!
