We have a Windgate 3-Lite Patio door and would like to replace standard handle with a keyed handle. Screws on handle are 3 15/16 inches apart. On inside screws are 3 1/2 and 5 1/4 inches apart.

I see you were looking at our 82-086, and I agree this handle set should work for you. If you need to replace the door's mortise lock as well, see our 82-227.
