Looking to add a keyed lock to this old Andersen sliding door.

Sure, look at our 82-316. This is an Andersen key lock designed to work with your style mortise. It's a left handed lock, as well, which is determined from the outside looking in and describes the operating panel. It seems to me that your operating panel is left handed from the outside, but see what you think.
