CODE CHANGE INSTRUCTIONS

MAINTENANCE

No maintenance of the working parts is necessary.

DO NOT OIL.

To maintain the nish the lock should be cleaned
regularly with a soft cloth. A silicone spray or similar
should be used to provide a protective lm against grit
and grime.

MANY CODES TO CHOOSE FROM

The CL500 code chamber (CL500, CL510, CL520)
consists of 11 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 rst digit of a code. Buttons may only be used
ONCE in a code. For example, 1212 is not possible.

A CL500 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 11 buttons, a total of 2,047 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 1,584.

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.

NOTE: CL505, CL515 and CL525 have 10 coded buttons
giving 1,023 different codes.

Take your CL500 lock off the door by unscrewing the
2 bolts in the backplate.

Press the C button to reset the chamber and place the
lock case on a at surface with the buttons down.

Remove the 4 red screws and carefully lift off the code
chamber plate. Check that all 12 springs are held in place
on the plate.

Note that the red tipped code tumblers correspond in
position to the existing code. The blue tipped non-code
tumblers ll 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 re­position 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.
