Codelocks CL525 Mortice Lock with Double Cylinder - Manual (Page 2)

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: Models 505, 515, 525 only – before changing the code make sure that the
lock is in Code Control Mode, with the slot in the bottom left button in the vertical
position.
1. Take your CL500 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 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 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 4 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 lever handle.
Most people will set a code in the range of 4 to 7 digits, and the total number of codes
in this range is 1584.
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.
NOTE: Models 505, 515, 525 have 10 coded buttons giving 1,023 different codes.
The CL500 code chamber (models 500, 510, 520) 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;
eg 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:
Access under control – the simple and easy way.
‘C’ plus 1 digit = 11
“2” = 55
“3” = 165
“4” = 330
‘C’ plus 5 digit = 462
“6” = 462
“7” = 330
“8” = 165
‘C’ plus 9 digit = 55
“10” = 11
“11” = 1
Total = 2047
