Some 08 cars have experienced issues when the battery goes dead. They loose the remote keyless entry and a couple of other functions. If my memory is not totally shot, a software update can fix this problem. Others with more knowledge will let us know.
Some cars, a small number of instances, have experienced issues with the BCM / ECM functioning properly after jumping them at the battery. They report that dealer fixes are required when this happens. Apparently if you use the positive lug on the under hood fuse box it avoids the potential for this issue. Stated another way, you might jump the car ten times at the battery and on the 11th try wipe the code in the ECM or BCM.
The automatic needs power to activate the electrical key interlock which is probably why your key is stuck in the ignition. If its not an automatic, then look at the ignition lock failure. If you have not had the ignition recall done on your car, the tumblers can fall out of the lock and prevent turning the ignition or removing the key.
If the battery is showing 13 volts and you are not getting any function out of the car, look at the terminals and the ground. If the volts are there but not driving the car then there has to be an issue with connectivity somewhere.
