Attempted to set combo on the lock and failed. Couldn't get the latch to work at the desired combination, nor the original 0-0-0. Sat there and went through every possible combo to get it to open again. About to give up when I read Marcus Me's 1-star review about lining up the grooves above the number dial. I had the lock open in SECONDS!! Now we never intended the lock to withstand serious thieves, more so to put off casual pickpockets who wouldn't be coming at us with wirecutters in hand. But a flashlight and a few seconds does the trick. What a waste of $!
