This issue will need to be diagnosed using a scanner at the dealership or repair facility, what may have occurred is when the battery went down the low voltage erased the programming. First step will be to attempt reprogramming. It is possible the battery went down because of an internal failure in the PCM, and it may have to be replaced in order to achieve reprogramming. This is best left to a professional with a good scanner to communicate with computer. Please accept my answer, if you have any further questions I will answer them until you are completely satisfied with my answers

Why does the radio and fan from heating work. Then the door windows won't roll up. Power controlled and interior lights or exterior lights not work. It is a new battery installed and still can't get key out of ignition.

Programming for these items is stored in the BCM of which only a scanner can diagnose,
