'02 V70 Keyless Remote?

I now have an '02 V70 wagon which came with just one key and one keyless
remote. My mechanic gave me a 2nd keyless remote but told me that the dealer
would have to program it (actually program the car for it). I recently had
to go to the dealer to get the leaking fuel pump replaced under extended
warranty.  At that time I asked for a 2nd key and to have that keyless
remote activated for the car. The dealer asked if I had the code that came
with the remote. When I said I didn't he told me that he could not program
the car without it and that a new remote was a couple of hundred buck plus
this, plus that, etc.  I asked if I would be able to get into and operate
the car with just the spare key; he said "yes" and I just opted for a single
new key.

It seems kind of strange that a dealer can't activate the remote from the
S/N on the back rather than needing a code that no one knows the instant
after it becomes separated from the remote.  Is it true that there is no way
to activate a remote without the papers that came with it? It seems like
Volvo believes that all Volvo owners have baskets of cash with nothing
better to do than spend it at the dealer.
