I made a 4 digit door lock made with redstone. I did not watch any torturial or anything, but i spent some hours making this pretty large redstone contraption that open a door by entering the right 4 digit code. There are signs with further instructions in the world itself. There is also a bonus building with villagers that attracts zombies whom gets pushed into lava when touch the building.
