Patio Door Lock

A home owner from Twain Harte, CA says:
This is a 45 year old patio door that I would like to convert to be a key locking unit from the exterior. The only marking I can find on the door is "Hilite Convertable". It has a 4" spread for the screws and the door is 1" wide. Can you suggest any new lock set unit I can purchase from you?

I think you should start by looking at our 82-063. This is for a HiLite door. Let me know what you think.
