You missed the point. You don't tell them its for a Yanmar. You just go in and say you want a key for a John Deere 850 tractor. And they will sell it to you. There is no need to tell them, what you are going to use it for. I don't know of anything, that you buy from anyone, that you have to tell them what you are going to use what you buy from them for. I agree, if you go in and run your mouth, about what you want it for, they won't sell it to you. I go down and buy a computer, they aren't going to ask me if I am going to use it for email or what ever, it just isn't done. I'm not trying to be nasty, its just the way it is.
