The code chamber (models 0460 and 0470) 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 code, or combination, can be entered in any order or
sequence; eg 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:
‘C’ plus 1 digit = 13
“2” = 78
“3” = 286
“4” = 715
“5” = 1287
‘C’ plus 6 digits = 1716
“7” = 1716
“8” = 1287
“9” = 715
“10” = 286
‘C’ plus 11 digits = 78
“12” = 13
“13” = 1
Total = 8191
Note: models 0465 and 0475 have 12 coded buttons
giving 4,095 different codes.
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 5 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 5 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 4 or 6 digits. Shorter codes
are possible, but 1 or 2 digit codes are not recommended.
MAINTENANCE
No maintenance of the working parts is necessary.
DO NOT OIL. To maintain the finish the lock should be cleaned
regularly with a soft cloth. A silicone spray or similar should
be used to provide a protective film against grit and grime.
CODE CHANGE INSTRUCTIONS
NOTE: On models 0465 and 0475: a) press the 'Y' button
and the 'C' button to ensure that the lock is not in passage set
mode, b) when changing code do not reposition 'Y' tumbler.
1. Take your PushButton lock off the door by unscrewing
the 2 bolts in the backplate.
2. Press the C button to reset the chamber and place
the lock case on a flat surface with the buttons down.
3. 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.
4. Note that the red tipped code tumblers correspond in
position to the existing code. The blue tipped non-code
tumblers fill the other positions. The C tumbler is not
coloured.
5. 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. The square notches of ALL tumblers MUST face
outwards, with the coloured tips ON TOP: See diagram
below. DO NOT force the tumblers in.
NB: Holding the C button depressed whilst removing
or replacing the tumblers is ESSENTIAL to avoid
damaging the internal mechanism. DO NOT attempt
to reposition the C tumbler.
6. Replace the code chamber plate carefully with the
2 red screws.
7. Check the operation of the new code, and make a
written note of it before re-installing the lock.
8. Fit the blue or red tipped spindle into the cam on the code
side according to the hand of your door (see below).
Fit the butterfly spindle into the cam on the Non-code side
(see below).
