If a Body Control Module (BCM) is also going to be replaced at this time, check the "RF-HUB, BCM, FOBIK REPLACEMENT AND PROGRAMMING ORDER GUIDE" before proceeding. Refer to MODULE REPLACEMENT GUIDE (RF-HUB, PCM, BCM, ESL)  .

NOTE:

Do not put a Laptop or other wireless device (cell phone, cell phone, audio device, and others) on top of or near the center console (between the seats to the dash). The Low Frequency (LF) antenna is below the center console and these devices may interrupt programming. Make sure that the key fob that is being programmed is inside the vehicle away from nearby consumer electronics. Disconnect aftermarket cell phone chargers before attempting to program the key fob.
