Thread: Not able to get 98 GP into key fob reprogramming mode

The BillBoost method should do the trick:

program the them again.

1. Remove the key from the ignition.

2. Close all doors.

3. Remove the "MALL PGM" fuse from the fuse panel. Use the legend on the fuse panel or
*** owner's manual to properly locate the "MALL PGM" fuse.

4. Insert the key into the ignition, and turn to the ACC position.

5. Turn the key to OFF and then back to ACC within 1 second.

6. Open and close any vehicle door. A chime will be heard when the system enters into
*** programming mode.

7. Press and hold the remote LOCK and UNLOCK buttons simultaneously for 14 seconds.
************* IMPORTANT: After 7 seconds, a chime may be heard confirming successful
*** synchronization. It is necessary to wait approximately 14 seconds for a second chime
*** that will confirm successful programming.

8. Repeat step 7 now for each additional remotes to be programmed including any existing
* * remotes.

9. Remove key from ignition.

10. Install the "MALL PGM" fuse back into the fuse panel and test remote(s).

new fobs are all over e bay.

Typically the fob is bad, happened on my '01. Possible but unlikely is that the main unit (BCM) is bad.

So I'm not EXACTLY sure at what point it worked so I'll do a play by play of my experiance.

First I tried the Billboost method. Nada.

Then I found the other method. Still nada.

So then I started experimenting.

In all cases, when I did the Billboost method it wouldn't ding once to signify "time to program".

Mine would ding once AND flash light the Seat Belt Warning lamp in time with the single ding
Then it would do 2 dings with the light flashing twice in synch.
Then 3
Then four

Then it would repeat 1,2,3,4. SO I canceled the "programming (key off)" and tried again. Same result.

On the 3rd attempt I'm a little hazy on the actual step but it occurred in one of 2 ways.

Pull PGM Fuse as Billboost states
Key to ACC/Off/ACC. open door close door
Either I let it cycle 3 times in a row (1,2,3,4..1,2,3,4..1,2,3,4) and it stopped then I held the unlock/lock key for a few seconds at which time I got a single beep. Continuously holding it did nothing else for 15 seconds.

OR

During the cycle (of it doing it's 1,2,3,4 crap) I held both Unlock/Lock and which time the cycle stopped and nothing happened for a few seconds then a single ding.

In BOTH cases after the first fob, I grabbed the second one and again after a few seconds of holding Lock/unlock I got a single Ding. This time I held it for 30 seconds with no further ding.
Turned off key, replaced Fuse and tested both fobs to find them successful working.


I guess the point I'm trying to make is that instead of entering a "program" mode that is stated in Method 2 my particular girl had her own way of doing things with the way I described.

Follow his procedure to the point of turning on the ACC the 2nd time and open/close the door but instead while it's doing it's thing, hold down both buttons and see if it stops cycling and wait for a single ding.....OR ......let it ding until it stops on its own then hit the buttons.

Reason why I state the 2 different ways is the fact I mighta hit the buttons when it finished on it's 3rd cycle as a coincidance OR I did interrupt it. Dunno, my FOBS were working and didn't care lol
