Jim,
My 54 has a hood release handle is attached to a cable located to the left of the steering wheel fastened to the lower part of the dashboard, this operates a cable that runs to the primary latch on the hood lock. When the handle is pulled back, the spring on the hood lock should pop the hood open far enough for you to be able to reach between the hood and the radiator support and unlatch the secondary lock while you lift the hood. Once you get this open lube all this stuff (including hinges) so it doesn't bind up on you again BEFORE closing, you'll get'er, just keep at it.
