Even with those four numbers there are countless possible combinations. Good luck with figuring out which one is the right one you punk.

*straightens calculator*

It’s pretty likely that it’s a four digit number, and as there are four digits chosen there, that means that there cannot be any repetition. This means that there are:

n!/(n-4)! possible orders. As ‘n’ is 4 (number of digits available). 4!/0! which becomes 4x3x2x1/1 which simplifies to 24. That means that there are 24 possible combinations of codes. This would take you about two or three minutes to input all possible codes.

Unless an alarm goes off if you don’t get it right in 3 tries.
