They come locked down (with a tie or a plastic rod) set at 000. Holding the latch to the left (when the latch is unlocked and open) allows you to set the combination of your choice. If 000 doesn’t open it, it’s whatever the original owner made it. Try, 001, 002, 003... and you’ll have it in less than an hour.
