Call a local lock and safe company (try yellow Pages) that handles Eagle range - would be the quickest option - it is meant to be a safe anyway . . . .one onllne with a helpline is Saunderson Security 0800 376 0700 or another is Needasafe on 0800 073 1590 who have a technical helpline and opening tech. line - may be able to help. There may be a master code that over-rides any combination
Course, how do they know its your safe . . .?
Only other way is a happy 5 hours with a hired jack hammer and lift the floor around it, relay and repair. . . .
