I have a safe i was just given by an work friend, he gave me the supposed combo and two keys (both marked with an LG)
The combo is 4 sets of numbers with Right - left - right - left written under each
I attempted to open it with the combo but am not sure of the proper sequence of clearing / turns / when to use the key etc
I appreciate any help - and look forward to cleaning the safe up and enjoin it
