I thought you meant you were replacing the lock above the plate area.
According to my book, in order to remove the latch there are three screws: one behind the lock, and two right next to it, much closer than the ones in your pic. The book doesn't mention anything about the touring model. Those circle look a lot like the plastic retaining clips elswhere in the car. You may be able to pry them up and out, and then remove the trim.
