How to install a door deadbolt lockset.
A primary component of a door is its deadbolt
lockset. Installing a deadbolt lockset may seem difficult at
first, given all the precision holes that must be made in a door,
but with the right tools and determination, it can easily be done.
Caution: When dealing with sharp objects, such as
a power drill, make sure you take precautions;
read all product manufacturer instructions.
Tape the deadbolt
lockset paper template to the door, per the deadbolt lockset
manufacturer's instructions, around 6 inches from the
center of the doorknob.
With either a
sharp pencil or awl, mark the hole center points, per the
manufacturer's instructions, through the taped-on template and
onto the door underneath such a template.
Upon making the
necessary marks and then removing the template off the door,
with a power drill attached with the appropriate drill bit, drill
in the lockset center hole as a precursor to the saw-hole
with the power drill attached with the appropriate hole saw, drill
in the lockset hole through the door, using the appropriate
center-point marking made earlier as your guide.
Next, use the
power drill attached with the appropriate spade bit to drill in
the lockset bolt hole on the edge of the door, using the appropriate marking made
earlier as your guide.

Then, with the
mechanical assembly of the lockset inserted, on top of this
bolt lockset hole found on the edge of the door, place the
deadbolt lockset plate in position and make an outlining of this
plate and markings of where the plate screws will go with a
In preparation to
chisel out a recessed frame/mortise for the permanent placement
the deadbolt lockset plate, temporarily remove the mechanical
assembly of the lockset and put two scrap pieces of wood on the
door--one on each side of the door--that make up the sides of
the lockset bolt hole, securing such pieces of scrap with two
clamps; make sure the clamps do not block the view/access to the
outlining of the lockset bolt plate. (The clamps will be
properly screwed tight when the screw swivel and metal
protection pad of each clamp have scrap pieces of wood in
between them and the actual surface of the door.) The
whole purpose of clamping on scrap pieces of wood around the
door sides of where the lockset bolt plate will be secured is to
prevent any possible splintering of the wooden door when
With the clamps
securely in place, use a chisel and hammer to chisel out
the outlining of the deadbolt lockset plate so as to make a
recessed frame in the side edge of this door for the permanent
flush placement of this plate.
out the recessed frame for the deadbolt lockset plate, next use a
power drill with the appropriate drill bit to drill in pilot
holes that will ultimately be occupied by screws that secure the
deadbolt lockset plate.
lockset bolt mechanical assembly into the newly made deadbolt
lockset hole and follow this by the flush placement of the
deadbolt lockset plate into its recessed frame/mortise; secure
the deadbolt lockset plate by screwing in the appropriate screws through the
previously made pilot holes with a screwdriver.
deadbolt lockset bolt set in the locked position (while the door
is opened wide) so as to have the bolt stick out, and per the
manufacturer's instructions, attach the lock cylinder (with its
plate) and thumb-turn plate (that operates the lock from the
inside) to the door deadbolt lockset,
making the appropriate internal connections with the
already-inserted mechanical assembly of the lockset, and
screwing in the appropriate screws of both the lock cylinder and
thumb-turn plates with a
screwdriver; read the lockset manufacturer's instructions for
any additional, relevant information.
Now, use the
thumb-turn and keyhole to see that the deadbolt lockset operates
correctly with your hands and key, respectively.
Mark the end of
the deadbolt that sticks out of the lockset with either lipstick or
a grease pencil, then retract this deadbolt by turning the
While the deadbolt is kept retracted, completely shut the door so that the door is normally
aligned with its door frame (as normally is the case when shut).
With the door shut, cause the deadbolt to stick out (while in
the door frame) so as to inherently make its marking on the corresponding
latch door frame to determine where you will need to make your
next cut; you may need to retract and then cause to stick out
several times while the door is shut in order to get a good
marking (with the tip of the deadbolt that, again, has been covered with
either lipstick or a grease pencil).
Open the door
with the deadbolt retracted again by turning the thumb-turn in the
Take the strike
plate of the deadbolt lockset and place it on the latch door frame side
where the lipstick-or grease-covered deadbolt of the lockset made
its marking; the marking should be visible in the center of the
opening of this strike plate, as this marking is the center of
where a hole will be bored for the deadbolt when the door is
properly closed and locked by the deadbolt. With the strike plate placed as so on the latch
door frame side, make an outlining of this plate with a pencil, and
use either the same pencil or an awl to make markings of where
the plate screws will go.
Use the power
drill again, with the appropriate drill bit, to drill a hole
in the latch door frame, using the deadbolt marking on the frame
made in the previous step as a guide. This hole should be
7/8 of an inch in diameter and 1 inch deep to ensure
that the deadbolt will fit in the door frame when the door is
completely shut (and the deadbolt sticks out as a matter of
engaging its locking mechanism).
the same method to chisel out a recessed frame/mortise for the
permanent placement of the lockset bolt plate, now chisel out a
thinner recessed frame/mortise for the permanent placement of
the strike plate on the latch door frame, following the previous
outline of such a plate as a guide in the process.
out the recessed frame/mortise for the strike plate, as may be
necessary, put the strike plate back on the latch door frame
side where it should be to remark the markings where the plate
screws will go with a sharp pencil or an awl.
Next, drill the
pilot holes in the latch door frame, using the appropriate hole
markings as guides.
Place the strike
plate into its recessed frame/mortise, making sure that the
plate is relatively flush with the rest of the surface of the
latch door frame; secure the strike plate by screwing in the
appropriate screws through the previously made pilot holes with
