what trim are you trying to remove? if its the dent trim, most of it has plastic spring clips that hold it. i believe the springs are on the bottom so you would have to lift up on the trim, then pull the top away from the body, then let it drop down. the ends of most pieces will have a nut inside the body panel you have to find and take off too. i think some also have a screw but that would be obvious. the racetrack trim i believe just has nuts on the inside of the body panels although i have never removed any. the wide trim along the bottom i believe is similar to the dent trim. if you have any more problems ask again.
