I don't use a tool. I use a thin spring steel paint scraper. I slide it between the trim and the edge of the body until I contact a clip, then I bend the trim and clip forward while gently working the trim up with my other hand. Eventually you will bend the clip far enough to pop the trim up. I just move on to the next and do the same thing. I've learned not to trust my ability with those tools, and the day I tossed mine... I stopped damaging trim and paint.
