Trying to find this door handle replacement

A friend from Ladera Ranch says:
My friends locking mechanism snapped and so I assume she needs a whole new handle/locking mechanism. Can you advise a replacement part? Thanks. Julie

Take a look at handle 82-031 to see if that matches up to yours. Also check to see if your internal mortise latch is in good working order.
