Lori deadbolts, manufactured by Ilco Industries, are high quality mortised deadbolts available in both thumb latch and double-keyed models. Whether you are removing the Lori deadbolt to refinish or replace the door, or as part of a security upgrade, the procedure is a simple one to complete.
Open the door.
Detach the slide bolt faceplate from the door edge by removing the two flathead screws using a Phillips screwdriver.
Remove the thumb latch assembly from the interior side of the door, if applicable, by removing the two screw bolts on either side of the latch handle, then pulling the assembly horizontally from the door.
Slip the long shaft of a 5/16-inch Allen wrench into the space on either side of the slide bolt to engage in the cylinder set screws and turn the set screw counterclockwise two to three full turns to loosen. Repeat for the set screw on the other side of the slide bolt.
Remove the deadbolt cylinders by turning the cylinders counterclockwise until the cylinder is free of the mortise housing. You can insert the deadbolt's key into the cylinder for leverage in turning the cylinder. Repeat for the opposite side cylinder in double-keyed models.
Pull the slide bolt assembly from the door edge, then remove the cylinder housing from the door hole.
