Can’t get into your safe? Lost your combination?

BIG RED^® does not retain the combinations of the safe lock.  These are held by the safe manufacturer. If you have a safe equipped with a BIG RED^® lock in your home or business and have lost the combination, first contact the safe manufacturer.  If you do not know the safe manufacturer or are experiencing other problems, contact a local locksmith or certified safe technician for assistance. These can be found in your local yellow pages or the links below.
