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?
