This isn't a problem with the theft deterrent. This is more likely a problem with the body control module. It needs diagnosis, but if I were to guess at this, I'd say you're probably going to end up needing a new module, which must be programmed by the dealer before it will work.

For these reasons, my recommendation here is to get professional diagnosis and repair, this is outside the realm of DIY repairs. What you're experiencing is a communication failure between multiple modules, likely because the body controller has stopped working. This module controls the lights, dimming, theft deterrent, and other functions on the truck.
