This is a combination lock that has 9 numbers to choose from, and 5 when pressed in the correct order complete the combination. This is an alternative to the original combo locks that took lots of redstone and logic gates. This one instead uses command blocks. You can easily change the combination on this because all you need to do is edit the parameters in one command block. You no longer need to rewire a big setup. It is also somewhat compact (22 wide X 23 long X 12 High). All feedback and comments are appreciated.
