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.
