I have an American Eagle gun safe manufactured by Cannon Safe. The base of the combination dial is loose. I have to hold the base up and go throught the combination about ten times to get it open. Sometimes it seems to help if I rattle the dial base and door handle. I am concerned that it will get worse and I may never be able to get it open. I have removed the inside door panel but do not see a simple way of adjusting the lock assembly. Have any of you had this problem? Do I need to call out a lock smith?
