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.

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).
