replace lock and handle

Thanks for reaching out to us! Your patio door handle set is an exact match for the 82-086 Legacy Keyed Handle. The mortise lock, sold separately from the handle set, resembles the 82-218 Mortise Lock. 

We do not have an exact replacement for your keeper but I believe you can use the 89-021D Diecast Keeper to replace it. To determine if these are the right fit for your door, you'll need to carefully compare the dimensions, which can be viewed on the website.
