I changed all the exterior door locks from brass kwikset locks to both Satin Nickel and Aged Bronze. I thought the door knob locks could have felt a little more stout.  A couple of the locks have a click when turning the knob and pushing the door open.  I've made minor adjustments to see if that helps, but it doesn't. I also adjusted and repaired stripped screw holes on all of the door frames and hinges, to eliminate door sag, which happens over time - the door settles within the frame.  So I knocked off 2 stars on the rating due to quality concerns.  I'm pretty handy with tools and watching you tube videos.
