Door security

A quick learner from Orlando Florida says:
I have this door on a home i just purchased which won't allow egress because there is bo way to lock the door. In the process of repairing this would it be possible to upgrade the locking mechanism.

Hey there. Please take a look at the 82-002K handle set, or the 82-002WK, which is the same but with a white finish. These look like the same type that should match your patio glass door. Compare them with yours and see what you think. They both come with a key lock and keeper. We also sell the keeper by itself under the 89-003, as well as the 88-009 chrome pull handle if you needed it
