Mechanical Keypad Door Lock provides secure locking while avoiding the
hassle and cost of dealing with providing, duplicating, or replacing keys. Unlike keyed locks, the
lock code can be easily changed by the user at any time. The code is not sequential, so the code
letters/digits can be entered in any order. Since it is completely mechanical, there is no need to run
wires from a power supply or replace batteries. The inside handle always operates to allow safe
egress in an emergency.

The Lock Code:
Each lock assembly is given a random code at the factory
and that code is printed on a card shipped with the lock. The
code can be easily changed as shown below.
NOTES:
A. When changing the lock code, it is crucial that you
press and hold the "C" button throughout the duration
of the code changing process. Failure to do so will
damage the lock code module.
B. Never remove the tumbler from the "C" position (Fig. 2).
C. Take care to insert the lock code tumblers properly. The
red or blue marks on the code tumblers should all be in
line if the code tumblers are inserted correctly.
D. Place a drop cloth on a good, flat surface to help
prevent screws and code tumblers from accidentally
bouncing off the table and getting lost.
E. The lock code is not sequential. In other words, if the
lock code numbers are 135Y, any sequence (Y135,
513Y, 3Y51, etc.) will unlock the door
IMPORTANT: Failure to adhere to the above could result in
a damaged lock code module or lost parts.
Changing the Lock Code
1. From the back of exterior assembly, remove the 4 RED
lock code plate retaining screws (see Figs. 1 and 2).
2. The factory setting uses 5 RED active lock code
tumblers, 8 BLUE inactive lock code tumblers, and 1
code clearing tumbler in the "C" position.
IMPORTANT: Never remove the code clearing tumbler
from the "C" position.
3. Determine the desired lock code and write it down to
avoid any mistake. Use that to determine which code
tumblers must be replaced. Red code tumblers
represent the code and blue code tumblers represent
the numbers/digits that are not part of the code.
4. While pressing the “C” button, use the provided tweezers to remove one or more code
tumblers as needed for the desired lock code (the numbers for each button are etched into
the housing next to its corresponding code tumbler, see Fig. 2).
5. While continuing to hold the "C" button down, insert the appropriate colored code tumbler(s)
as needed. Ensure that each code tumbler is inserted such that the side with one square cut
is facing the outside of the housing (see Fig. 3).

Determine Door Swing and Handedness:
Prepare the Door and Install the Latchbolt:
Setting the Lock Code (Continued):
1.
Fold the template on the dotted line and place it on the door
so that the line marked "Latch center line" is aligned with the
latch strike plate's center line when the door is closed. Use
tape to hold the template temporarily in place (see Fig. 5).
2. Drill the six 3/8" (10mm) holes as shown on template.
3. Viewing the door from the latch edge, mark the horizontal
center point on the "Latch center line" and drill a 1" (25mm)
hole to a depth of 33/4" (95mm).
4. Use a chisel to form the 4 horizontally-aligned 3/8" (10mm)
holes into a single slot.
5. Insert the latch into the latch hole and mark around the
faceplate to determine the size of the recessed area needed
to allow the faceplate to be flush with the door.
6. After marking around the faceplate, remove the latch and
use a chisel to cut a 1/8" (3mm) deep hole as marked. This
will ensure that the faceplate fits flush with the door (Fig. 6).
7. Insert the latch assembly, ensuring that curved part of the
latchbolt is correctly oriented for the door's swing. Secure
the latch assembly with 2 wood screws provided.

or
left-handed.
When facing the door from the outside, if the hinge
is on your right, then the door is right-handed. If
the hinge is on your left, the door is left-handed
(see Fig. 4).
6.
Replace
the lock code plate and
secure
it
with
the
4 RED screws.
7. Check the code to ensure accuracy before installing. First press the "C" (Clear)
button followed
by the chosen code and move the handle on the keypad assembly to test the lock.
IMPORTANT NOTES:
A. Spare code tumblers are provided to increase the number of code digits if needed.
B. Carefully note each code tumbler's orientation as it is inserted into the lock code assembly.
The square cut should be oriented toward the outside of the housing.
C. Do not leave any code tumbler position empty.
D. Store the manual, actual code, and unused code tumblers in a safe place.

Prepare the Door and Install the Latchbolt (Continued):
Changing the Interior Latchbolt Handedness (for left
-
handed doors)
NOTES:
A. The interior lock assembly is set for right-handed doors from the factory. You should only
need to set the handedness of this unit if your door is left-handed.
B. The exterior lock assembly is already set for left-handed doors from the factory.
Interior Lock Assembly
1. Hold the interior handle assembly as it would be oriented for the handedness and swing of the
door to determine the correct handle orientation.
2. Loosen the set screw (see Fig. 10) and rotate the handle to its correct horizontal position if
necessary (see Fig. 11). Tighten the set screw to maintain handle position.
3. Check that the lever handle now turns in a clockwise direction and returns freely.
4. Viewing the interior handle assembly from the back, note the blue handing screw's location—
right side for left-handed and left side for right-handed doors (see Fig. 11).
5. If necessary, remove and change the location of the blue screw depending on the orientation
of the interior handle.
Positioning the Spindles
8. Choose the correct spindle that best matches the door's thickness.
For doors less than 17/16" (37mm), use the shorter spindle 215/16"
(75mm). For doors 17/16"~115/16" (37~50mm) use the 33/8" (85mm)
spindle. For thicker doors, use the 315/16"(100mm) spindle.
9. Position the spindle in the center, through the latch hub (Fig. 7)
according to the door's handing as shown in Figs. 8 and 9.

1.
Select the appropriate screws depending on
the door's thickness. For doors less than 17/8"
(48mm), use the shorter 17/16 (36mm) screws.
2. Fit the neoprene seals to both the exterior and
the interior handle assemblies (see Fig. 14).
3. Screw the two hexagonal mounting posts in
place to the exterior handle assembly (Fig. 14).
4. Hold the exterior handle assembly onto the
door with the spindle in place and ensure that
the latchbolt support post engages the hole in
the latchbolt assembly.
5. Hold the interior handle assembly in place on
the inside of the door so that the spindle is
properly set in the handle interior handle
assembly hub.
6. Screw both sides together using the machine
screws on the top and bottom.
7. Before final tightening of screws, make sure
the door lock is vertical. Test to make sure the
lock functions correctly and moves easily.
NOTE: DO NOT over-tighten the machine screws as this can lead to poor operation or damage
the lock assembly.
8. For right-handed doors, change the exterior lever handing at this time.
a. To prevent damage from forced entry the external handle is fitted with a clutch.
b. To change the handle's orientation, simply apply force to rotate the handle to its proper
handing (see Fig. 15).
9. Check that the set code is able to unlock the door before closing it to avoid being locked out.
Exterior Handle Assembly
The handedness of the external handle assembly (default,
left-handed) will be set after installation.
Installing the Latchbolt Support Post
From the back of the exterior handle assembly, fit the latchbolt
support post in the correct position. For right-
handed doors, the
support post should be fitted on the left. For left-handed doors,
the support post should be fitted on the right (Fig. 12 and 13).

1.
Partially close the door and mark where the
latchbolt contacts the door frame.
2. Close the door. With the door in a closed
position, measure the distance from the
door latch to the edge of the door frame.
This is the door latch line. This is shown as
“X” in Figs. 16 and 17.
3. Open the door and mark the door latch line
on the frame.
4. Using the strike plate as a template, mark
the outer edges of the strike plate, the inner
hole and the screw holes.
5. Using a chisel, cut a 1/16" (1mm) deep
recess for mounting the strike plate so that it
fits flush with the frame. (Fig. 18.)
6. Use the strike dust box as a template to
mark, drill, and chisel out the latchbolt hole
to a depth of at least 1/2" (13mm) to
accommodate the strike dust box (Fig. 18,
dotted lines).
7. Insert the strike dust box into place along
with the strike plate. Secure both with the
provided wood screws.
8. Test that the door closes easily and that
latchbolt fits securely into the strike plate
aperture. Ensure that that the deadlatch
(Fig. 19) does not enter the strike plate
aperture. If it does, loosen and reposition
the strike plate as necessary.
To unlock the door:
1. Press the "C" (clear) key to make sure that no keys are already pressed or partially pressed.
2. Press
each key in the lock code in any order. The lock code is not sequential and therefore the
keys can be pressed in any order. For example, if the lock code numbers are 135Y, any
combination of these numbers (Y135, 513Y, 3Y51, etc.) will unlock the door.
3. Turn the lever to open the door.
In case of an error or if the door doesn't unlock, press the "C" (clear) key and press the keys in the
lock code again.

The code doesn't unlock the door.
 Press the "C" (clear) key and enter the passcode again.
 Ensure that each key (including the "C" key) has been fully
pressed.
 Remove the lock and the lock code plate to ensure that each
letter/digit in the chosen code is represented by a red code
tumbler and all other code tumblers are blue.
 Remove and reinsert the code tumblers, ensuring that they are
correctly oriented and fully inserted.
The latch lever turns, but the latchbolt
does not retract
 The spindle used is too short for the door's thickness. The
spindle must be long enough to simultaneously engage both
the interior and exterior levers. Use a longer spindle.
