dad-blasted remote

hey ya'all, just bought a 1999 tahoe LS, didnt come with the door remote,so i got one on e-bay,same serial # as OEM, the instructions tell me to hold down the door lock button,and cycle the ignition on/off 2 times,then release the lock button....then the doors are supposed to cycle lock/unlock on there own,well that doesnt happen,therefore the remote cannot program,any ideas as to why truck isnt responding? Thanks in advance

Not sure if yours is the same as mine but that only works on some years. I have a 97 and i had to use a paper clip and jump two spots together on a plug that is under the dash below the steering wheel. Try this...

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.

Thanks Amigo, i'll give that a try,im used to a diesel,and a more primitive system. all this wiring's making me crazy
