OPERATIO AL OTE:
Prior to beginning installation, please check that all parts are working
correctly. Press the “C” button 3–5 times. Enter the code from the factory
supplied code card. Turn the outside knob clockwise and release. The knob
should return easily under spring pressure. If you intend to change the code,
you should do it before installing the lock (See Code Change Instructions).
Make sure that the inside handle moves freely. Make sure the latch holdback
button will engage and hold the handle in the “latch–open” position, if it is a
model with latch holdback. If you intend to remove the latch holdback feature,
you should do it before installing the lock (See Removing the atch Holdback).
Check that the latch bolt moves freely by pressing the bolthead at the end,
and also by turning the flat spindle in the latch cam.

A. DETERMI I G THE HA D OF YOUR DOOR
Many of the installation instructions refer to
the handing of your door. The hand of the door
is determined with the door in the closed position,
from the exterior or pushbutton side of the door.
A) Right Hand Door. Door opens inward
(push). Hinged on the right side.
B) eft Hand Door. Door opens inward
(push). Hinged on the left side.
C) Right Hand Reverse Door. Door opens
outward (pull). Hinged on the right side.
D) eft Hand Reverse Door. Door opens out-
ward (pull). Hinged on the left side.
B. MARKI G THE TEMPLATE A D DRILLI G THE DOOR
B-1 Find and remove the template from the installation manual. Carefully fold
along the dotted line that matches the backset the application requires.
B-2 From the exterior (or push button side) of the
door, place the dotted line of the template along
the edge of the door.
B-3 Carefully mark the 4 holes on the template
(2 mounting holes, 1 tailpiece/spindle hole, 1
latch support post hole).
B-4 Drill the 4 holes, making sure to drill them straight. The latch support
post hole will only be drilled on the side matching lock/latch installation.
C. I STALLI G THE LATCH
C-1 Using the center line of the latch (marked on template), mark the point
where the cross bore for the latch should be drilled.
C-2 Drill a 1" (25 mm) diameter hole, 3 3⁄4" (96mm) deep, on that center point
of the edge of the door.
C-3 Insert the latch into the hole and outline the face of the latch (already
prepped on most metal doors). Remove the latch.
C-4 Using a chisel, remove the material 1⁄8" (3 mm) deep from the door for
the faceplate of the latch (already prepped on most metal doors).
C-5 Reinsert the latch and install the latch using the mounting screws provided.

D. I STALLI G THE LATCH SUPPORT POST
Install the latch support post into
the back of the lock as shown.
For right-hand doors, use hole A.
For left-hand doors, use hole B.
E. I STALLI G THE TAILPIECE / SPI DLE
E-1 For doors ranging in thickness from 1 3⁄8"
(35 mm) to 1 3⁄4" (44 mm) use the shorter
tailpiece (supplied) and align as shown.
E-2 For doors ranging in thickness from 1 7⁄8"
(48 mm) to 2 1⁄2” (64 mm) use the longest
tailpiece (supplied) and align as shown.
E-3 Make sure the tailpiece/spindle matches
the picture shown depending on the hand
of the lock.
F. I STALLI G THE LOCK
F-1 Place the rubber gaskets around the lock
body with the lock body sitting into the recessed portion of the gasket.
Assure the holes in the back of the lock and the gasket match.
F-2 If using the cover plate (supplied), place it on the back of the lock
between the gasket and the door (extra length of the cover plate should
be placed so that it is below the unit)
F-3 For doors ranging in thickness from 1 3⁄8" ( 35 mm) to 1 3⁄4" ( 44 mm), use
the shorter mounting screws (supplied) and align as shown
F-4 For doors ranging in thickness from 1 3⁄4" (44 mm) to 2 1⁄4" (57 mm), use
the medium mounting screws (supplied) and align as shown.
F-5 For doors ranging in thickness from 2 1⁄4" (57 mm) to 2 1⁄2" (64 mm), use
the longest mounting screws (supplied) and align as shown.

ote: Assurance that the proper
tailpiece/spindle is used is extremely
critical. If the wrong spindle is used,
binding or a lockout can occur.

F-7 Finger-tighten the (2) mounting screws, assuring the lock is vertical and
sitting flush against the door.
F-8 Before final tightening, make sure the code works and all features on the
unit work as intended.
F-9 Tighten the mounting screws firmly, being careful not to over tighten the
screws, as this may cause the lock to function poorly or not at all.
G. I STALLI G THE STRIKE PLATE
G-1 Push the door nearly shut to locate the center line of the
latch bolt. Mark the center line on the door frame.
G-2 Using the strike, align the center of the strike opening with
the center just marked.
G-3 Carefully trace the outside profile of the strike. Also trace the latch hole in
the strike.
G-4 Using a chisel, carefully remove approximately 1⁄16” (1 mm) deep worth of
material from the traced area (already prepped on most metal doors). The
latch face plate should sit flush with the edge of the door.
G-5 Drill or cut a recess in the door frame for the latch bolt in
the center of the strike latch hole, traced earlier.
G-6 Place the strike into the newly chiseled area, making sure
it sits flush and there are no obstructions in the latch hole
of the strike (remove any obstructions or debris).
G-7 Install the strike plate with 2 screws provided.
H. REMOVI G THE LATCH HOLDBACK
H-1 If this feature is not needed, it can be removed by unscrewing the 4 corner
screws from the inside unit assembly and removing the metal plate. The
latch holdback button, a small spring and ball bearing, should be removed
and discarded.
H-2 Install the plastic clip enclosed to cover the latch holdback button hole. Reinstall
the metal cover plate and resecure with the 4 screws removed earlier.

ote: Do not close the door until the lock has been tested and you are
confident it works properly.
Make sure to account for any weather stripping or door stop if
necessary.
OTE: The dead-latch must not fall into the latch hole. The dead-latch
protects against manipulation of the latch bolt. If the dead-latch is able
to fall into the latch hole, remove the strike and reposition it so this
condition does not happen.

I. CHA GI G THE CODE
I-1 Remove the lock from the door.
I-2 Remove the 4 retaining (red) screws from
the back of the outside unit assembly.
Take extra care to keep the outside unit
assembly on a flat surface when you are
removing the cover plate because there
are many small components inside.
I-3 You will now see that there are 5 red
color coded tumblers and 8 blue colored
un-coded tumblers, plus 1 clear tumbler
(‘C’ button).
I-4 To change your code, hold the outside unit
assembly with the push-buttons facing
down. Press the “C” button and hold it.
If the “C” is not held in while changing
the code, the lock can be damaged.
I-5 Using the tweezers supplied (or small
needle nose pliers), you can easily
remove one or more of the coded and un-
coded tumblers.
ote: The red tumblers represent coded
digits and the blue tumblers represent
non-coded digits.
ote: NEVER remove the ‘C’ tumbler.
I-6 Please note the different shapes of the tumblers before reinserting them
into the lock body. There is a difference in shape between the coded and
un-coded tumblers as illustrated. When refitting the tumblers into the lock
body, they must be fitted facing the correct way as show in the illustration.
ote: All square cutouts must face outwards. The bump on the tumbler
(either color) must fall into the machined slot.
I-7 After you have refitted the tumblers and made a note of the new code,
replace the metal cover plate with the 4 screws.
ote: With the spare tumblers provided, you can either increase the number
of digits in your code to 6-7, or reduce to 3-4.

J. Trouble Shooting
Installation Issues:
?The latch cannot be withdrawn when entering the code
The lock has been fitted to the wrong hand hung door
All locks were set to fit right-hand hung doors. The lock needs to be
removed from the door and reversed. Refer to instructions.
?Both the inside and outside knobs retract when turned towards the door frame.
The spindle is in position at the wrong angle.
Remove the lock from the door, and reposition the spindles as shown in the
instructions.
?The knob will not turn after entering a new code.
One or more of the code tumblers are turned the wrong way
Re-read the code change instructions and check that the red tumblers are
all facing with the square notches facing outward.
?The latch bolt does not move smoothly in or out.
The lock is not installed correctly.
Check that the lock is square on the door and positioned accurately over
the latch. Check that the latch is positioned horizontally and parallel to the
door surface. Check the spindle length. It may be trapped between the
front and back plate if the spindle is too long.
?The outside knob turns after entering a correct code, but does not retract
the latch.
The spindle is too short for the door thickness.
If the spindle is too short, then it will not engage with both the outside knob
and the inside handle at the same time. It may also slip out of one side
after same use. Replace the spindle.
Post-Installation Issues:
?The outside knob turns freely without retracting the bolt.
The knob has been forcibly turned.
Return the lock. Someone may have tried to force the knob to gain entry.
?The inside lever handle does not return to the upright position after operating.
The lever return spring is broken.
Replace the return spring.
?The latch does not engage. The door remains unlocked after use.
The latch is not entering the strike.
Your door or frame may have warped since the lock was installed. Check
that the latch bolt is lined up with the strike hole. Realign the position of
the strike as necessary. Make sure the deadlatch does not fall into the
strike hole.
