If you don't already have it, the door sill clips will come out undamaged using this tool from Amazon for $6.50 (
hyperlink)....without it, you will mar up your paint and bend up the plastic clip...the clips must unfortunately must be removed, and slid into the plastic sill trim before reinstalling the trim....the clips slide in from opposite directions, or you could just slide the trim in back on the clips without removal (Re: the gray clips with a rectangular head)
The tool will also come in handy in a lot of other areas of you car....
Nice writeup.
