remote
Thanks for the reply. I have already tried that method with no success and thought that maybe I had other problems too. BUT........I guess my truck was manufactured late in 1999 and they titled it a 2000 and there were some difference in programming techniques. I got my remote programmed today using the 1999 program method. It took me all of about 10 seconds. Stealership was going to charge me $45.00. For anyone who might be interested....here's how you do it:
QUESTION: 1999 GMC Suburban - how do I program key fob?
ANSWER: Hi
Here is EXACT procedure from GM SI.
If they key is in the ON position during the programming procedure, the horn chirp will be disabled, if the key is in the OFF position, the horn chirp will be enabled. The horn will chirp when the lock button is pressed two times.
When reprogramming the remote control door lock reciever, All transmitters must be programmed at this time in order for the transmitters to operate the vehicle. Transmitters not programed at this time will not work and the procedure will have to be redone with all the transmitters.
Ground pin 4 to pin 8 of the data link connector (DLC). The receiver will respond by locking and unlocking the doors, and activating the liftgate window release (if equipped) within 2 seconds.
Press and hold the LOCK and UNLOCK buttons simultaneously on the first transmitter to be programmed until the locks cycle (approximately 10 seconds).
Repeat step 2 for up to four total transmitters to be programmed (if available). The receiver will respond by locking and unlocking the doors and activating the liftgate window release (if equipped) within 2 seconds.
Remove the ground applied to the DLC.
Lock and unlock the doors in order to verify the transmitter operation.
Activate the rear window release in order to verify the transmitter operation.
The DLC is the connector around the drivers knees.
It is wherwe they plug into to check the Service Engine Soon Light.
It has a small tab on either the top or bottom.
The Tab is pins 9-16.
I Hope this helps
