Replacement Patio door handle

Hello there. Something like our 82-030 should be able to replace your old handle set; however this set works with a number of different mortise locks, so if you need the mortise lock as well please show us clear photos of it so I can identify it for you. Many thanks. 

Perfect, thanks. That looks like the 82-265 Mortise Lock, which is indeed compatible with the 82-030 Handle Set. For a new keeper, see the 82-249. Let me know if you have further inquiries!
