Hi all,
I have a safe that I would like to open. It has a combination lock and a keyhole lock as well. The safe is made by M. G. Dyke and Sons. From the Internet searches I have made, it seems unusual to have 2 locks on this sort of safe. Was it standard practice in those days (approximately the 1950s) to have both kinds of lock on this sort of safe?

Does it mean that my efforts to open the safe will be doubly difficult? Not only will I need to crack the combination, but I will need to find a way to open the keyed lock.

Is this too big a challenge for a novice safe-cracker!?
