OK, why can't you open the trunk again?
You can't forget lights on with a Cobalt, they turn off automatically after 10-12 minutes, even if you turn them on after you take the key out of the ignition.
If you don't even have a dome light, this means it's your battery, battery connections or "BCM" fuse. If you have dome and radio then it could probably be your run crank fuse or Boost post has come loose.
If your key is stuck in the ignition because you have no power, you can insert a pin under the steering wheel to release the key from cylinder.
Never drive faster than your guardian angel can fly
