So I bought a new case and never set the codes from 000 but were driving over to drop my son off at school today and he randomly starts rolling them around on one latch. It was in the open position when he did this but he has inadvertantly set a combination and he has no idea what it is. Now it is locked and can not be used on that latch. Can you re-set these without knowing the original combination? How can I get this thing open to use the latch again?
