Adding exterior lock to sliding glass door

Question

My sliding glass door has a latch lock inside but there is no way to lock the door from the outside. I would like to replace the hardware so we can lock and unlock the door from the outside. Unfortunately, I don't see a brand or stamp anywhere in the door frame to identify the model. Do these photos give you any clues for options/solutions?

Thanks for writing in. Your outside pull looks like our 82-044. This can be fitted with the 82-315 Key Lock & Housing. See the video below for details.
