I have a v60 master lock for a locker, how can i find the combo to open it again?

Take the lock if at all possible to a locksmith. You might be able to find one on fixya's directory. All locks have a code on the back. Manufacturers will not give the key codes or combos out so you will need a locksmith. The locksmith will contact the manufacturer or look up in his book your combo. For security reasons they are recalcitrant about giving you the combo unless you walk in with it. Otherwise you may have to call them out. The service call stinks but how do they (the locksmith) know that you are the actual owner of the lock? So they will need to verify all that. I hope this locks your problem in.
