Reflectolyte patio door lock is broken

Thanks for posting! I think we can help, but we won't be able to replace this part by itself. This looks like the latch from our 82-005 handle set, but unfortunately we cannot supply the individual components individually. I apologize for the inconvenience. 

The latch in the 82-005 can be removed, yes. Refer to the video below.

I'm starting to have doubts now, though. I've never seen a latch like yours installed in the door itself. I cannot guarantee if the 82-005 latch can work in the same capacity.
