Believe stereo wires where factory amp was shorted something lost all power. The headlights work nothing else. Both door lights stay on like four fuses blew but replacing did not fix the problem. OBD reader says BCM and sunroof control. Does this sound like burnt BCM or how can I test no power to button key won't open doors?

It does sound like the BCM is out, but we need to do a CAN scan to see what codes come up.

You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:

Here is how to change the BCM out in case a code comes up for it, you can get a preprogrammed unit by searching Google or Ebay.

Well, my scanner will work but the regular code reader says not. How do you go about fixing where it gets power? What does it sound like an immobilizer problem?

Do you have a CAN scanner? Also did you recheck the fuses that blew to see if they went bad again?
