How to install/replace door knob:




Step 1:



Remove the Old Doorknob
Begin by removing the screws holding the doorknob in place. The screws will be located on the interior side of the door.

If your doorknob has screws on the cover plates, remove those to loosen the old knob. If not, look for a small slot with a metal piece on the side of the handle. Then use a clip or the key from the new doorknob to push in on the metal piece as show in the image. That should make the doorknob pop loose.

Step 2:

Remove the Underlying Plate
Pull off the doorknob to reveal the plate below. Look for a slot in the plate along the seam where it butts against the door. Wedge a flathead screwdriver in the slot and then give the plate a half twist to pop it off.


Step 3:




Remove the Old Screws and Latch
With plate removed, you'll see the screws you should remove with a power drill (Image 1).

Remove the old latch by taking out the screws with a power drill or screwdriver (Image 2).


Step 4:

Install the New Latch and Doorhandle
Depending on your door, you may need to adjust the backset, the distance between the edge of the door and the center of the doorknob. Most doorknobs can accommodate different backsets.

Reverse the removal procedure to install the new doorknob. In most cases the holes for the new doorknob will match your existing holes. Be sure to orient the new striker in the correct direction to ensure that the door will close properly.

Screw the new latch in, setting the screws by hand first and then tightening them with a power drill. Set the doorknobs in place, set the screws by hand, and then tighten. Don't over-tighten the screws or you'll bind the doorknob.

Test the new handle to make sure it turns and locks properly.



Deadbolt:





How to install/replace deadbolt:

Step 1:



Reference the Manufacturer's Template
Most deadbolt-lock manufacturers provide a template to help you install the lock. The template is designed to work with doors of different thicknesses and has reference points that may be marked on the door with an awl. The deadbolt should be at least 6" above your doorknob.


Step 2:




Cut a Hole for the Deadbolt
After you mark the reference points from the template, use a hole saw to begin cutting the hole for the deadbolt (Image 1). When the pilot bit on the hole saw comes through the other side of the door, stop cutting. Finish the hole from the other side of the door to prevent splinters. If your hole saw isn't deep enough to penetrate the exterior face of the door, use a standard bit to finish drilling the hole you'll use as a reference point (Image 2).


Step 3:



Use a 7/8" spade bit to drill a hole through the edge of the door for the bolt.


Step 4:



Mortise the Area Around the Faceplate
Dry-fit the bolt into the hole, and trace around the faceplate. Use a wood chisel to mortise the area around the faceplate so that it will be flush with the door. When using the chisel, keep the beveled side in toward the mortised area, and tap the tool deep enough to recess the faceplate. You may need a smaller chisel to mortise the rounded corners.


Step 5:

Secure the Bolt To the Door
Continue mortising until the faceplate fits properly. Drill pilot holes, and secure the bolt to the door with screws.


Step 6:

Install the Cylinder And Thumb Lever
Dry-fit the cylinder and thumb-turn plate so you'll know how the pieces fit together. Fit the exterior side onto the door first, making sure the writing is upright. Then set the interior piece in place, and align the screw holes with the mounting holes inside the lock. Fasten the deadbolt in place with screws.


Step 7:



Drill Holes and Secure the Strike Plate
Mark the end of the bolt with lipstick or paint. Close the door, and turn the deadbolt several times to mark the doorframe. Use a 7/8" spade bit to drill two overlapping holes in the doorframe for the deadbolt.

Mortise the area around the hole so the strike plate will fit flush with the doorframe. Drill pilot holes and secure the striker plate with screws.
