How To Install A Deadbolt:

You don’t have to be Mr.Fix-It to perform the installation of a new deadbolt.

Spring-loaded doorknobs can’t be counted upon to keep you and your loved ones safe. Installation of a new deadbolt lock that can only be opened with a key from either side is a small price to pay for peace of mind, and it’s a quick, easy way to upgrade your door! Just add a fresh coat of paint and some shiny new hardware, and you’re all set.



1.  Your Manufacturer’s Template Exists For A Reason:

Your deadbolt-lock undoubtedly came with its very own manufacturer’s template for ease of installation. The template will work regardless of how thick your door may or may not be, and its reference points should be marked right on your door with an awl. Be sure to measure at least 6” above your knob.

2.  Cut A Hole For Your Deadbolt:

Once you’ve marked the reference points from your template, you’ll want to get right into it and start using a hole saw to open a hole for the installation of a new deadbolt. Once your hole saw’s pilot bit has made it through to the other side of your door, cease cutting. Finish the hole off from the other side of your door to keep from getting splinters! In the event that your saw isn’t deep enough to penetrate through to the exterior face of your door, use a standard bit to wrap up drilling the hole you’re going to be using as a handy reference point.

3.  Drill A Hole Through To The Other Side Of The Door:

Pretty much exactly what it sounds like. Carefully, using a 7/8″ spade bit to drill a hole through the edge of the door for the bolt.

4. Mortise the Area Around the Faceplate

If you’re wondering what on earth a mortise is, it’s a hole cut in a post or other piece of wood, in which another piece of wood cut to fit it, called a tenon, is put. Get your bolt right in that hole, and trace clearly around the faceplate. Making use of a wood chisel, mortise the space around the faceplate so it’s right up against the door. Be sure your chisel’s beveled side always faces the mortised area, and tap the tool with enough force that the faceplate is recessed. You might find that a smaller chisel comes in handy when it’s time to mortise the rounded corners!

5. Secure The Bolt To The Door

Don’t stop mortising until the faceplate has been correctly fitted. Drill pilot holes, and secure the bolt to the door with screws.

6. Install The Cylinder And Thumb Lever

You’re very nearly done. The thumb turn plate and cylinder must be fitted so that you see how the pieces are intended to fit together. The exterior side goes on the door first, and be sure the writing is right-side up! When you’ve got the interior pieces where they’re supposed to be, the screw holes must correspond to the mounting holes in the lock. The deadbolt is set in place with screws.

7. Drill Holes, Secure The Strike Plate

The end of the bolt must be marked, preferably with paint, but lipstick will do just fine in a pinch! Close the door, turning the deadbolt multiple times so as to properly mark the doorframe. Making use of your 7/8″ spade bit for the last time, drill two overlapping holes in the doorframe for the deadbolt and mortise the spaces around the hole, so the strike plat sits right up against the doorframe. Drill more pilot holes, and set the striker plate with screws.

And you’re done! That wasn’t nearly as hard as you thought it’d be, was it?
