2007 Silverado: disconnected battery, now won't crank

My husband disconnected the battery because he was trying to fix the radio. Needless to say he hooked the battery back up and the truck won't crank. There is definitely power getting around because the warning lights come on, the radio comes on and the a/c will come on but the truck won't turn over. Last time he did this he called the gm place and they told him something to reset but he doesn't remember what it was. They are closed now and we leave for vacation in the morning. Can anyone please help?

I have read everyone's post tonight cause I had all these problems after changing my stereo and on star antenna. I also removed my battery with my key on (don't do it lol) so after that I had major issues. Gears wouldn't shift and my dash looked like a Christmas tree and dinging so I turned the key on and off 3 times then removed the battery again (with the key out and doors unlocked) waited 30 minutes then reconnected the battery with the negative side first cause its a pain to get to. Afterwards turned key on and waited 30 seconds before starting and now everything is back to normal. I'm not bragging but I guess I'm a genius. If anyone needs some more help welcome to call. 573*429+0172
I ask because I'm having a similar problem with my 2004 4x4 Silverado, along with wonky gages and overhead lights that don't come on when I open the door. It's like half of the interior electrical works and the other half doesn't. A couple of other data points: The transmission was replaced about three weeks ago, and the problems started after I parked it and it sat for a few hours. Didn't disconnect the battery or anything else.

Someone please help us. My truck is doing the same thing. I did not disconnect the battery, but was listening to the radio for about 15-20 minutes, tried to start it and no crank. ac blower, radio, one speed on wipers, low beam lights, message displays service 4 wheel drive and service airbag when key is on. Door locks, windows, dome lights and door open chime does not work and of course does not crank. Have checked all fuses and relays and all is fine. Mechanic says it is the BCM, but I do not know. Before shelling out the money for one I want to make sure it has failed and why it failed.

My husband's mechanic told him to try that out and it didn't work for us. :/ We have to tow it to his shop now so he can see what the problem is.
