problem removing door knob
 

The problem is an entry door with a knob that has no detent, no obvious hole to push in and would not pry off. I'm attaching pictures that show the door knob. Any suggestions on how to remove the doorknob without destroying the hardware?Attachment 2985

There may be a set screw, look for a small hole with a hex head inside, the set screw is like a screw but without a head. Generally they are on the inside door knob on the under side.
