Things you need


Before you get started, it is important to gather the right tools. The tools you will need to install an internal deadbolt lock are:
-Drill and drill bits

-Hole saw

-Measuring tape

-Hammer

-Dust mask

-Safety goggles

-Wood chisel

-Combination square

The first step is to close the door and trace the inside of the bolt hole onto the doorjamb. You will need to reference the traced line later.

The installation can begin with installing the strike box into the door jamb. After that is in place the latch bolt can be slid into the bolt hole. The outline of the latch plate should be traced on to the edge of the door. The bolt can then be removed and a mortise for the latch plate chiseled. After this, the bolt and latch place can be fitted back into place.

If the latch plate of the internal deadbolt lock is not flush with the edge of the door, it may be necessary to shim or deepen the mortise to make it flush. After the latch plate of the deadbolt is flush with the edge of the door it should be screwed into place and the bolt should be set in the unlocked position.

Next, the cylinder should be placed into the cylinder hole from the outside part of the door. When installing the deadbolt it is especially important to consult the manufacturer's instructions at this point, sine each deadbolt lock will be slightly different.

If the internal deadbolt has a thumb latch, that latch should be aligned with the cylinder, and then secured to the inside of the door. At this point the bolt should be checked to make sure that it operates properly.

The next step is to drill a hole for the bolt, using the mark made on the door jamb. Again, it is important to refer to the manufacturer's instructions, as these instructions will provide the exact diameter of the hole that is needed.

Next, the strike plate should be placed over the hold and the outline should be traced on the door jamb. After that a mortise should be chiseled for the strike plate and the plate can be screwed to the jamb.

For deadbolts that use a strike box, the bolt hole can be enlarged in order to accommodate the strike box, and the mortise can be chiseled for the strike box and strike plate, after which they can be screwed to the door jamb. The lock should then be tested to make sure it operates properly.
