Amazon sells a lockset. "Sliding Glass Patio Door Handle Set with Mortise Lock, White, Keyed, 3-15/16 Screw Holes by TechnologyLK " That would work.

Hi Martin

A dead bolt lock for a regular door and a

lock for a sliding door unfortunately are two completely different mechanisms and operate in very differnt ways. You must go to

a specialty locksmith shop ( Don't only go to one ) get a few ideas. Locks and catches for a pocket door is sort of what you are looking for , but obviously in your case , for a Exterior application and key operation. this is not something you will be able to buy on line or at a HD.

The door looks fairly new. I would try to contact the builder or a window/door specialist to actually come and have a look and get some ideas.

I am not sure what your application is, but what about a security bar in the sliding track of the door? This will not work from the outside however.

Another option might be a magnetic strip lock that can be installed on the glass door and can be operated by a key to turn on and off.
