Where I suggest starting is just remove the outside door handle, with
lock cylinder in it.
( one large phillips head screw holdsthat handle  in place, the screw
head is hidden under the rubber seal on the edge of the door.
it hooks into the hole in the door at the forward end. _

I would just try lots of lube to start with. LOTS.
Sometimes I might even remove a latch mounting screw just to be able to
shoot lube in the latch mechanism.

I have not seen any fail the way you describe.
It may be that yours is somehow actually broken and a good used latch
assembly is what you really need.

Have fun !

I’m hoping to feel out the problem.  tips on what to look for or possible repair needed appreciated.  At this point not only does the key turning not do anything but the lock will not go up or down from the inside either.  luckily it is stuck in the unlocked position so the door opens and shuts normally.
