Does anyone know how to program the OBS (1998 Silvy) keyless entry fobs?? I know its a little more complicated than the NBS. THANKS!!

 

Here ya go...
Transmitter Programming
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.

1. 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.
2. Press and hold the LOCK and UNLOCK buttons simultaneously on the first transmitter to be programmed until the locks cycle (approximately 10 seconds).
3. 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.
4. Remove the ground applied to the DLC.
5. Lock and unlock the doors in order to verify the transmitter operation.
6. Activate the rear window release in order to verify the transmitter operation.

 

First, the pins dont have #'s, so how do I count?? left to right and top to bottom right?? If so, I stuck a paperclip in each pin and nothing happened. Do the doors have to be open or closed, also does the key have to be in the on or run pos, also we did this on a 99 Denali and I remember having to remove the radio fuse. Sorry about all the questions, I checked the battery and its good but I'm not 100% sure that the fob even works, I just want to make sure that I'm doing everything right and not missing a step or something. THANKS for the help!
