Good evening: During my last move, I lost the key to my Henry 2K2 Power Amp. I purchased this Amp. Some time a go as none working. I now have the time, but do not have the key that fits it. I wonder if all 2K2 units share the same lock? If they do, I would be more then pleased to purchase a copy. Thanks. Warren WW1HH ww1hh at cvok.net
