There is a common mechanical type of keypad where the actual combination doesn't matter as long as you hit the numbers. I mean, the order of the number doesn't matter. Say the combination is officially 2134 then 1234 also works, as does 4321, etc. As long as those four digits get pressed in any order, it works. My last four workplaces have had this type of lock. I used to prank co-workers who didn't know this with the "wrong" number.
