MANY CODES TO CHOOSE FROM
The CL100 and CL200 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 CL100 and CL200 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
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.
1. Take your CL100 or CL200 lock off the door by
unscrewing the 2 screws 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 re-positioning
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. Insert the spindle, with the spring on the code side. On
latchbolt locks the spindle must engage the latch as follows:
Red tipped code
tumbler with square
notch in low position
Blue tipped non-code
tumbler with square
notch in high position
Section through lockcase
showing square notches in
tumblers facing outwards
Door hung on right viewed from outside
Door hung on left viewed from outside
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.
