I am going to move your question to the tahoe section of this forum. You are more likely to find a answer there. Good luck.

1.Locate theData Link Port. It is locatedunder dash drivers side. Be sure you know which pins are8 and4.
(Notice port iswider on top row)

2. Make sure there are metal contact pins in terminals 8 and 4. Connect 8 to 4 with a suitable jumper wire (leave the jumper wire connected throughout the programming procedure). Make sure you know which terminals are 8 and 4. The vehicle will respond by locking and unlocking the doors to signify entering of programming mode.

3. Press and hold both the LOCK and UNLOCK buttons together on the first transmitter to be programmed. After about 15 seconds, the vehicle will respond by locking and unlocking the doors. Release the buttons on the transmitter.

4. Within one minute, repeat the previous step on the remaining transmitters to be programmed.

5. Remove jumper wire applied to the OBDII Port.
