I wouldn't count on that too much...
I tried a couple of dealers and they would look it up and their computers. When they saw that the VIN wasn't in it anymore, they told me it couldn't be done.
The closer I got to getting my 1989 240sx's car key copied was at auto gouverneur. Speak with the director of the parts dept. He told me he'd send the VIN over to nissan and have the info retrieved. I couldn't test it thus because I ended up scrapping the car for parts instead of using it in the end. So the key wasn't an issue anymore. I'd try that route if you want a car key copied.
