The CL300 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.
The CL300 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:
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, the code length can be changed to 5 or 7
digits. Shorter codes are not recommended.
Code Change Instructions
1.Take your CL300 lock off the door by unscrewing the 2 screws in the back plate.
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 coloredtipped code tumblers correspond in position to the existing code. The silver tipped
non-code tumblers fill the other positions. The C tumbler is not colored.
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 square 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.
