Hello I am looking for programming instrctions for a 2000 pontaic bonneville se and also a 2004 grand prix gtp. after searching this forum only found the bonneville and that needs a scan tool? is this the only way? Thanks

Unfortunately, I think you will need a scan tool for both of your vehicles.

Here are the instructions for a 99 Bonneville, should be the same:

Transmitter programming per the GM manual:

Important:

Before entering the programming mode, verify the possession of all the transmitters you will be using on the vehicle. Once you program the transmitter, the memory erases the other transmitters. You may program up to 4 transmitters

1) Turn OFF the ignition switch

2) Usa a fused jumper (3 amp is sufficient) and connect terminal 8 (back/white wire) to terminal 4 (black wire)

3) Close all the doors

4) Turn ON the ignition switch
the doors will lock

5) Press and hold the following buttons on one of the transmitters for 30 seconds:
lock and unlock

6) After a 30 second delay, the doors will lock and unlock

Important:
DO NOT turn OFF the ignition . If the switch is turned OFF the first transmitter becomes inoperative.

7) In order to program extra transmitters repeat Step 5

8)Disconnect the fused jumper wire from the data link connector

9) Turn off ignition

10) Verify functions of all programmed transmitters.

Here's what I found, at least for the 02 Grand Prix

2002 Pontiac Grand Prix

Transmitter Programming

Important
All transmitters which are to be recognized by the remote control door lock transmitter (RCDLR) must be programmed in a single programming sequence. If the system is placed in program mode it will erase all previously programmed transmitters upon the receipt of the programming signal from the first transmitter. Up to four transmitters can be programmed. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle.


Remove the ignition key from the ignition lock cylinder.
Close all of the doors.
Remove the MALL PGM fuse from the fuse block.
Insert the ignition key into the ignition lock cylinder.
Turn the ignition to ACC. The body control module (BCM) will perform the following in order to identify the type of BCM installed in the vehicle:
Flash the seat belt indicator 1, 2, or 3 times.
Chime 1, 2, or 3 times.
Turn the ignition to OFF, and then back to ACC within 1 second. The BCM may begin to chime and flash diagnostic trouble codes (DTCs). If the BCM has stored any DTCs, refer to Diagnostic System Check - Body Control System in Body Control System.
Open and then close any vehicle door. The BCM will chime in order to confirm that the programming mode has been entered.
Press and hold the transmitter LOCK and UNLOCK buttons simultaneously for approximately 14 seconds.

Important
After approximately 7 seconds the BCM will chime once to confirm that synchronization has been completed. After approximately 14 seconds the BCM will chime a second time to confirm that the programming has been completed.


Repeat the previous step in order to program each additional transmitter.
Remove the ignition key from the ignition lock cylinder.
Install the MALL PGM fuse into the fuse block.
Operate the functions of each transmitter in order to verify correct system operation.
