For help with installation of Atrium locks, please read The Atrium Lock Installation Instructions. 

To change to the 40024 (keyed) or 40031 (non-keyed) trim hardware you will have to drill a new hole about 5/8" above the existing top screw hole. The trim plate is longer towards the top and will cover the existing top screw hole.

The bottom portion of the plate is slightly smaller (~1/8 inch), and will leave a small part of the old trim imprints visible.

Priced and sold each.
