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).
