I have a 2000 Monte carlo SS and just reprogrammed the Key FOB last night. The Key can be in the Ign. in the ACC mode. You do not need to go to the dealer to take care of this....
1. Make sure that the RADIO POWER is off.
2. Hold in the DISP Button on the Radio Dash until the SETTINGS appears.
3. Cycle thru the options using the SEEK > button until you get to the FOB PROG Function(option 11)
4. Select this option using the RADIO PRESET button 1
5. The KEY FOB is ready to program. Hit the UNLOCK Button on the FOB. The door should unlock or lock now.
This info is also in the OWNERS MANUAL under the KEYLESS ENTRY section.
As for the KEY FOB ID, (ON BACK OF REMOTE)it is as follows:
GM / UTA 25678792
FCC ID: KOBUT1BT
CANADA: 1983 101 393
You will need to make sure that the remote that you get has these exact numbers on it, otherwise it will not work.
