this machine is on DemRedstonepOp's plot because i needed a safe place to build from learners :D
numpad is layed out like this:
reset 7 8 9
set code 4 5 6
0 1 2 3
enter the 10 digit code and if correct you can set a new one, this machine auto resets when the code its right or wrong but a reset button is available if you enter a wrong number by accident :)
