Ours broke as well. It would open from the outside but not the inside. I think Camco makes a generic one that fits. I saw it in a couple campground stores.
We had the trailer at the dealer a couple weeks ago for a couple other minor issues, and they ordered the part and installed it at n/c as a warranty job. Was pleasantly surprised on that. I wouldn't have blamed them for calling it normal wear and tear.

I can see buying a few these to carry as spares - that mechanism is pretty flimsy.
