Mine were just stuck on with 2-sided tape. Here's a trick, Take some fishing line (the stronger, the better) or some thin gauge wire and wrap the ends either around two bolts or your fingers and place it between the molding and the metal. Now gently work the fishing line up and down in a sawing motion, you can work your way down the side of the car and you will cut the molding off. Once you're done you will have to go back with some solvent and cut the adhesive. Let me know if you have any questions.
