Chances are the truck need a hard reboot or to be reprogrammed. I would try the hard reboot first, this video can help

If that doesn't work, the "Remote Control Door Lock Receiver" GM calls it the RCDLR or the BCM is bad, typical BCM codes that block RKE programming:

B3125
B3135
B3055
B3935
U0197/U0140 (module comm errors)

What we should do is a CAN scan which will give us codes to help fix the problem.

Please upload a short video in your response of the problem, so I can see what's going on :) Let me know what you find as well.
