CL400 - Code Change Instructions
Many Codes to Choose From
The CL400 code chamber (CL410 and CL420) 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; e.g. 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 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, the code length can be changed to 4 or 6 digits. Shorter codes are
possible, but 1 or 2 digit codes are not recommended.
