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.

NOTE: On models 415 and 425: 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’ or ‘C’ tumbler.

1. Take your CL400 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. Note: Fit either the BLUE or RED

tipped spindle to the code side

,

dependant on hand of door.

9. Fit the butterfly

spindle to the inside,

non-coded side

.

Most people will set a code in the range of 4 to 7 digits, and the total number of codes
in this range is 5,434.

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.

The CL400 code chamber (models 410 and 420) 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 CL400 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 digit = 1716
“7” = 1716
“8” = 1287
“9” = 715
“10” = 286

‘C’ plus 11 digit = 78
“12” = 13
“13” = 1
Total = 8191

MANY CODES TO CHOOSE FROM CODE CHANGE INSTRUCTIONS

MAINTENANCE

NOTE: Models 415 and 425 have 12 coded buttons giving 4,095 different codes.
