New lock or door handle

A quick learner from Olympia, WA says:
I no longer have keys to this door handle so I need to either re-key it, or replace the handle. I can't seem to identify parts for either option.

Thanks for writing in. I'm afraid we can't provide new keys; a local locksmith might be able to help. Otherwise, consider buying a new outside pull like our 82-044. You can adapt our 82-315 Key Lock & Housing to this pull. See the video below.
