Various key fobs info
The 2000 key fob is the same and will work on the 1997 - 1999 cars it just doesn't have the "passive" switch on it, which makes it a less expensive option to the 10253839 fob, however it is the hardest to find.
2001 - 2004 fobs will not work in the 1997 - 2000 cars.
1997 - 1999 $78.12 GM #10253839
2000 60.36 GM #10432147
2001 - 2004 60.36 GM #25695954 #1
2001 - 2004 60.36 GM #25695955 #2
You can change out the receiver on the 97 - 00 cars to the newer 2001-04 style, but you will also have to change your tire pressure sensors (TPS) and your key fobs. The TPS on the 01 - 04's are much cheaper than the 97 - 00 TPS.
Please note that I do not have any of these fobs or TPS for sale, I just gathered up this info and now I'm sharing it.
