Patio door lock

Question

I'm hoping to replace this lock and handle set for the patio door, would you please help me identify the parts to order.

Thank you,
Ann

This looks like our 82-265 Mortise Lock. For an accompanying keeper see the 82-249. If you need a new handle set as well, see our 82-086. I think this handle set should work, but it only will if the key lock and thumb lever are closer to the bottom of your older handle set, rather than perfectly centered. I can't tell for sure from these photos, so please send me ones that show the handle set more clearly if you're uncertain.
