What year is your car? On my 99 Accord (if I remember correctly), I had to remove the splash guards to take off the skirts. Then you will slide them either forward or rearward and then pull down. I found a local body shop to do the door mouldings, as I didn't feel like pulling the door panels myself to expose the mounting studs. But, I think the shop just pulled them off. There may also be double-sided tape. Body shop charged me $40 to pull the old ones off my sedan and put the new ones on.
