This sounds like the BCM has gone out, but I need to ask if you have checked the fuses?

Here is a guide to help and the fuse locations in the images below:

Here is how to replace the BCM in case you need it if the fuses are okay. You can get a preprogrammed unit by searching Google or Ebay.

Check out the images (below). Please let us know what happens.

Okay, then we should do a CAN scan to confirm the BCM failure. 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:

Please go over these guides and report back.

Does the scanner work on other cars? Please check all of the fuses with the key on, here are the wiring diagrams for the ALDL connector so you can test the connections with this guide:

So, the orange wire has power, and the black wire has ground, correct? Check out the images (below). Please let us know what you find.
