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 first 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; e.g. 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, 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.
Code Change Instructions
1. Take your CL500 lock off the door by unscrewing the 2 bolts 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 4 red screws and carefully lift off the code chamber plate. Check that all 12 springs are held in place on the plate.
4. Note that the coloured code tumblers correspond in position to the existing code. The silver 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 reposition 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.
Note: 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 4 red screws.
7. Check the operation of the new code, and make a written note of it before reinstalling the lock.
8. (See below)
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.
