Add keyock

Thanks for posting. I am afraid it might be difficult to adapt a certain key cylinder in this case. This is an Andersen door, and Andersen is rather particular about the hardware that is compatible with their doors. In this case, the compatible key lock adaptation is our 82-316 and 82-317. Handing determined by outside looking in by which panels is operating. Let me know what you think.

Correct. If from the outside, the operating panel (or rather, the panel that moves) goes from left to right, then you need the left-handed lock, the 82-316. Let me know if you have further questions.
