Hello, I will try my best to help you with your concern.

first you will need to double check all the fuses and make sure none are blown.

It is rare for the body control module to lose its programming but it can happen.

you will need to take the vehicle to the dealer and have them attempt to reprogram your key fob, power window and door locks
