need help with patio door locking mechanism

A quick learner from Maui, Hawaii says:
My part looks just like your 82-259, almost same dimensions. I need only the keeper for this unit. Some person installed the partial lock on my 93 old mother's door. I just now noticed that the keeper was not installed and there is no key to this lock.I found the lever and the lock pieces.

Now please inform me if I can just buy the keeper or all the different pieces
to make this work, so that my poor 93 old mother will be safe in her own home.
PLEASE HELP me with some good advise.
God bless you all. James

Hey, James! Many customers have been able to use our 82-249 as a keeper for the 82-259. Look it over and see what you think. I'm not sure about the other parts, though. We may be able to recommend a key lock, but I'd like to see a picture of the handle itself. That way we can find something compatible.
