Many
Codes to choose from ...
The PushButton code
chamber consists of 13 buttons from which
the code is selected, and a 'C' button which
is used to re-set the chamber after an incorrect
entry, and which must always be used as the
first digit of a code. Buttons may only be
used ONCE in a code. For example, 1212 is
not possible. A PushButton code, or combination,
can be entered in any order or sequence; e.g
1234 can be 4321 or 1342 or whatever sequence
is most convenient to remember.
With 13 buttons,
a total of 8,191 different codes are available, any of which
can be entered in any sequence.The total is
arrived at as follows:

Most people will
set a code in the range of 4 to 7 digits,
and the total number of codes in this range
is 5434. The lock is factory set with a randomly
selected 6 digit code starting with the C
button. The code is not recorded by the factory.
The code can be changed as often as required
to any other 6 digit code. Every new code
must start with the C button. Using the spare
tumblers, one red and one blue, the code length
can be changed to 5 or 7 digits. Shorter codes
are not recommended.
Code
Change Instructions
 |
Take
your PushButton combination door lock
off the door by unscrewing the 2 screws
in the backplate. |
|
Press
the C button to reset the chamber and
place the lock case on a flat surface
with the buttons down. |
|
Remove
the 2 red screws and carefully lift
off the code chamber plate. Check that
all 14 springs are held in place on
the plate. |
|
Note
that the 5 red tipped code tumblers
correspond in position to the existing
code. The 8 blue tipped non-code tumblers
fill the other positions. The C tumbler
is not coloured. |
|
Hold
the lock in your hand and depress the
C button. Keeping the C button depressed
use tweezers to re-position the tumblers
to correspond with your new code. DO
NOT force the tumblers in. |
NB:
Holding the C button depressed whilst
re-positioning the tumblers is ESSENTIAL to
avoid damaging the internal mechanism. DO
NOT attempt to reposition the C tumbler. The
square notches of all the tumblers MUST face
outwards with the coloured tips ON TOP.
|
Replace the
code chamber plate carefully with the
2 red screws. |
|
Check the
operation of the new code, and make
a written note of it before re-installing
the lock. |
|
On the spring
latch models 250 and 255, the spindle
must engage the latch. |
