How do you remove a Kwikset keyed latch
Loosen the set screws.
Pull handle off (may have to tap or wiggle handle to get it to come off).
Use a flathead screwdriver to pry the  escutcheon (rose, rosette) off (pry right near the dimple, to release the rose).
Once free, slide the escutcheon off.
Remove the screws that were hidden.
