"The cost for the machinery is less than what it takes to buy a brake turning lathe. " Would you mind stating what that price would be? I purchases a Used on car lathe for $1500, which was 10 years out of date. A new late would have set me back $5700. And you expect the keys to be given out free or at a ridiculously below cost price (parts/labor/equipment)?
Another thing, "If you are selling a product that can cost upwards of $35K or more and it comes equipped with an essential part that is easily lost or damaged rendering the product useless, then providing a low-cost means of replacement is just plain good service." Are you saying you purchased the Murano from a Toyota Dealer for $35K and expect the Nissan Dealer to make you a special deal? Why do you think that Toyota Dealer quoted a high price for the key? Didn't they need to get it from the Nissan Dealer? Nissan and Toyota are 2 entirely different companies with product lines that have nothing to do with the other. You simply purchased a car that was used as a trade-in, just as any other used car dealer does. BTW, I purchased my Murano NEW from a Nissan Dealer for $35K and it came will the 2 keys/fobs & a valet key. I'm skeptical you paid Toyota the $35K and are just quoting the new car price.
