Whatever PIN you choose can be entered in any sequence. It is called non-sequential PIN entry and means your chosen PIN code can be entered in any order providing the correct digits are used. E.g. if you chose 1234 as your code this could be entered as 4321, 3241, 1432 or any other variation of 1234.
This system applies to all mechanical push button locks. The only alternative is a
Dial Combo Lock Key Safe. The lock is similar to a bike lock with a PIN that must be entered in sequence.
