Code Change Instructions - CODELOCKS CL500 Instructions Manual

24/9/2561
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.
