It depends on the diameter of the snake and the size of the pipe it is in. If it is a 1/2″ snake and it is in the main drain, then it is most likely coiled up like a pretzel and will have to be dug op and removed from the other end. If this is the case, and you are lucky, it will be right where the pipe leaves the house. If it is outside the house, you have two choices. Dig it up where it is stuck, or pull on the rod until it either comes loose or breaks. If it comes loose that problem is solved, if it breaks you have to dig it up anyway. Your bigger problem is why it stuck.
