Need to replace all parts

Thanks for reaching out! Your patio door handle set looks like it can be replaced with our 82-030A Centered Keyed Handle Set. This handle set come with a new keyed lock and a compatible set of keys. Carefully look over the dimensions to confirm that this is a fit for your door.

Dimensions for 82-030A

Your mortise lock reminds me of our 82-218 Mortise Lock with a round face. Again, you'll need to compare the dimensions to confirm that this is the right replacement. This lock is sold separately from the handle set.
