Olympus sliding patio door lick

Thanks for reaching out! I am unable to confirm the correct replacement lock needed for your patio door based on the brand alone. There are a few different parts that come up when I search the brand so I'll need to see the design of your hardware to narrow them down.

May I please see a photo of your existing mortise lock and the compatible handle set and keeper?

Thanks for the photos. It appears you have a version of our Legacy keyed handle set, part 82-087. To confirm that this is the replacement you'll need, carefully look over the dimensions and compare them to your existing lock set to determine if this is the correct replacement. Keep in mind, the thumb latch missing from your handle is not sold separately.
