Key locked in the ignition
Bad battery OR bad ignition switch. Pretty common. If it's your battery, charge it up or replace, your key will then turn back to remove. If you really want your key out right now, look up under the steering column, you'll EITHER see a hole under there OR an indentation where a hole was supposed to be. If the hole isn't already drilled out, drill out carefully, stick a paperclip end up there and release the key.
