Installing your used Exterior Locksets on a new door
The tools you will need to complete the project: Drill, 2 1/8” wood hole bit, (Steel if a steel door)1” spade bit, 1” wood chisel, hammer, Combination square, 1/8” drill bit tape measure, Phillips screw driver and pencil.
This article is those that have installed a new door and would like to install their used locksets. If you have bought new locksets, a detailed set of instructions will come with the locksets.
Install the lower handle set first, not the top deadbolt. The center of the handle set will be 37” from the ground. Mark on the door with your pencil 37”, now using your combination square set the heel against the door, narrow part and mark a line approx 3 “ in on the door, do the same on the other side. Make a line across the narrow part of the door at this same height and on the door jamb.
Measure in from each edge of the door on this line 2 3/8 inches. Using the 2 1.8 bit, drill the backset on one side until you see the small drill bit start to protrude on the other side. Check that the drill bit is in line with your mark, if not you will need to adjust your bit.
Remove the bit and drill on the other side of the door, this will prevent it from splintering if the bit were to go all the way through.
On the line you made that is on the thin side of the door, mark the center point with your pencil. Drill with your 1” spade bit until it goes all the way into the larger hole you just drilled. Insert the latch into the 1” hole, mark the outside of the plate.
Using your 1” wood chisel, remove the wood necessary to allow the plate of the latch to sit flush with the door. When you are flush, make a mark in each of the holes and remove the latch. Using a nail tap on these holes until you have created a dimple, next drill a pilot hole at each of these dimple points. The dimples will keep the drill bit from getting off the mark. Insert the Latch back in the hole and secure using screws.
Insert the outside handle first then the inside handle. The hard part, depending on the handle set, is lining everything up. Hold the inside handle back so you can see where the screws attach to the other side, insert the screws and just get them started. Some styles you might not be able to do this
Your might also have latch style. After you have completed the above tasks, depending on style, the bottom part will either screw into the door or you will need to drill all the way through the door and attach the latch using your long screw. You need to make sure the hole lines up with the screw hole.
On the door jamb, make a mark the same distance in as the Latch on the other side, should be in the center.
Using a 1”drill bit, drill through the jamb. Close the door, the door should latch.
Open the door and lay the strike plate in the center and as close to the edge as possible. The small tongue on the inside of the strike plate should touch the hole. Hold this in place and make a mark around the strike plate. This is the wood you need to remove, but only the depth of the plate. Start by using your wood chisel and follow the wood marks, just on the inside of the line you just draw.
Lay the strike plate in the chiseled area and mark the two screw holes, using the nail and hammer, dimple the pencil marks, pilot the holes and install the Strike Plate
The DEAD BOLT should be installed 5 inches above the lock set you just installed. You will pretty much follow the same procedure. The main difference will be the jamb side. Usually the 1” hole will need to be deeper, and you will need to chisel deeper for the extra plates. Also you might have one plate you will need to screw in first with very long screws and then install another plate over it. If so make sure you pilot the screw holes. If you have a hard time getting the screw to go all the way down, put a little soap on the threads.
