6-digit coded doors

Hello, this is my first project and it took me fro about 2-3 days. This are 6-digit coded doors with reset button, lever for lock, torches that indicates button state...
Code is: 1-on
2-off
3-off
4-on
5-on
6-off

I did not hide it so you guys can see how it works.
I am pretty shure that you will know how to change the code =)

Fell free to use it and edit it!!

P.S. : PLAY ON PEACEFUL ONLY!!!
Craters in the world were fails =)
Map is really laggy, or it is just my computer.
I do not speak English so don't be angry if I has misspelled something =)
