The plate locking mechanism of the door handle

The locking mechanism of the sliding door handle is broken. I need a replacement. The sliding door will no longer lock. I would be grateful if you can advise where to get replacement.

It seems the plate fallen inside at the bottom. I suspect this cannot be reattached to the door handle assembly.

Thanks for posting. The only replacement we carry for your hardware is the handle set, part 82-078. Look over the dimensions and compare them to your existing hardware to confirm that this is the right replacement.

I apologize that we cannot provide you with a replacement for the other pieces of hardware.

Question- Is There a keyed tumbler to fit the 82-078 and work in the door in picture?

I'm afraid we don't carry the internal mortise lock or an outside key lock for this handle set. We aren't sure if they're available any longer. I am very sorry for the inconvenience.
