The difference is only $11 more for a 97 to 00 key fob. The tire TPS does seem to be much more of a price difference.
You can replace the entire key fob and TPS system with the newer (01/04) style. It doesn't seem to be too hard to update.
They changed a couple ways. '97 to '99 had a passive switch on the remote. The '00 did not have the passive any more, but still works with the buttons for all the '97 to '00 cars.
Upgrading to the newer '01-'04 system is pretty easy. I did it on my '99 in an afternoon. Doing it again would be shorter time.
