The lock is a four number combination lock. You have four sets of numbers, and one set missing the last number. In numerical order, you can count one to four in the tens place...but the number 14- is missing it's last number, and 166 doesn't fit. Maybe the number is "146?"
On the lock, you see the number "1" - as if it is the first lock. So, does 1-1-3 mean, "First lock, first number...?"
