These are 3 different versions of my new combination lock. The second and third (based on pictures) are incredibly compact for an order sensitive, 100% customizable combination lock. The first has an added feature of an indicator light which, while adding to the size, improves the security and overall appearance of the combination lock. The smallest one, in terms of square blocks, is the third one at only 16 wide, 4 high and 9 long. In order to change the combination on any one of these locks, simply move the "indent" of redstone along the top to whichever number you would like (unlike many other combination locks, you CAN use the same number twice in a row). If you like this project, feel free to comment/diamond/subscribe for more.

The current combination for all of these locks is 7063 (buttons go from 0-9)
