door kick plate removal

[studyolic]

Hello,
I want to replace the rubber door seal mounted on the car body that runs around the edge of where the door fits when closed. Along the lower edge it is underneath the edge of two plastic strips; on the inner edge it is under the edge of the black plastic strip that runs the length of the door sill, hiding the edge of the carpet. On the outer side, there is a black plastic kick plate that is fixed somehow to the sill. It looks like you could pry these up, at the risk of snapping some plastic clips. Does anyone know how to remove these plastic strips safeley, to allow replacement of the rubber door seal and neat re-fixing of the strips?

Thanks.
