Patio door lock replacement

Thanks for reaching out! Your patio door handle can be replaced with the 82-030 Sliding Patio Door Handle Set. You'll need to compare the distance between the installation holes to confirm that this is the right fit. 

The keyed versions of this set are the 82-030A (centered key lock) or 82-030B (offset key lock).

The mortise lock, sold separately from the handle set, can likely be replaced with the 82-260 Multi-Point Mortise Lock with Pocket Plate, which is compatible with the 82-249 Sliding Glass Door Multi-Point Keeper. Take a look over the diagrams below to determine if these are the correct replacements.
