Ok so I have a couple year old set of kwikset locks for my home, and all is good except for 1 of the 4 the key goes in upside down instead of the proper way. So I took it apart and can't figure out how to do it. There is no hole on the outside knob, so it has to be tricker than the older ones. Here is a pic of the back side of the lock.
