I. CHANGING 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.
Note
: The red tumblers represent coded
digits and the blue tumblers represent
non-coded digits.
Note
: 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.
Note
: 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.
Note
: With the spare tumblers provided, you can either increase the number
of digits in your code to 6-7, or reduce to 3-4.
