Keys Locked in Ignition, battery dead, 2007 Pontiac Torrent

On the Torrent/Equinox once the battery goes dead the ignition switch will lock the key inside of itself. If the battery was dead, without leaving the key in the ignition, and you tried starting it it wouldn't let you take the key out either. Some weird safety/anti- theft thing I guess. All you have to do is jump start it with another vehicle and jumper cables or a jump box/pack. Once the torrent has charged back up(20-30 min) and you shut it off the key will come out like normal.
