My latch assembly is broken? Not sure if that is correct part name or not. The button that protrudes from the handle and moves when you turn the handle no longer moves. Not sure what it is called. I have attached picture. I also cant find a model number just 081706911470716. Can you help

Sure, check out our 40-193 and see if this is a match. Carefully compare it to your own handle and see what you think.
