Many Codes to Choose From

The code chamber consists of 9 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 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 9 buttons, a total of 511 different codes are available, any of which can be
entered in any sequence.
The total is arrived at as follows:
It is recommended that the code is changed regularly to prevent compromise.
Code Change Instructions
1. Remove the lock from 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 10 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 re-positioning 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 2 red screws.
7. Check the operation of the new code, and make a written note of it before re-installing the lock.
8. Insert the spindle, with the spring on the code side. On latchbolt locks the spindle must engage the latch
