even at $250, it doesn't sound too bad. esp since your key would have the remote functionality.
the only reason i say that is because my friend lost his master key for his honda prelude, and it cost him 300 or so for a new key and ignition. it was going to cost him at least another 200 to get the remote and have that programed. not to mention changing all the key locks because the new key wouldn't fit! and added cost associated w/ that..
they mentioned that the parts (key and remote) were relatively cheap, but the programing fees was what drove the price up.
i suppose it's nice to have ignition protection codes in place, but once you lose your key, it'll be time to pay.. ....
