Mark where cylinder hole may need to be enlarged slightly to accommodate new 60mm backset. Remove lockset and enlarge hole. Reinstall lock and screw tightly in place.Install spindle and handles in place so spindle fits through handle-hole and thumbturn hole is lined up with cylinder hole in lock body. Screw in place.Install cylinder from the inside so key hole is on outside. Open door and install set screw just under deadbolt on edge of door.There are three options when it comes to replacing your deadbolt strike plate (diagram below):It is possible to reuse your original strike plate by moving it up or down with the door jamb to fit new lock. Alternatively, original strike plate may also be modified with a hack saw to fit new lock.Or you can replace strike plate with new strike plate (included in kit #40177). *Note: new strike plate has squared ends and door jamb will have to be modified; old cut-out may be visible on door jamb under new strike plate.Or new optional HOPPE strike plate (part #1963546) can be installed as an alternative; long enough and wide enough to cover old cut-out (HOPPE strike not included in kit).
