I think it's a bit different if you turn up with the car and a working key already - in that case making you another key doesn't really change anything about the situation(although I suppose it could still be someone just borrowing a car intending to use the spare to steal it later....).
But yeah, I specifically mean a situation where someone doesn't have a key, turns up with the car on a trailer and asks for the key for it - in that case yeah, why would a dealership unlock and provide you with a key for a random car that you can't prove ownership of? That would be just weird.
Yeah. That would be very weird especially if it were a dealership you had no previous dealings with. (I don't actually know how interconnected a manufacturer's dealership network is at the back end.)
