A five-digit pass code 2015-04-25
From Mary:

Question from Mary:

More on your published question:

I have the same type of lock, but set up a 5-digit pass code. Is that more or fewer possibilities than a 4-digit code. How many digits would make the lock most secure? I don't believe Werner specified this, but each number can only be used once. Thanks, Mary
