car wont start in cold please help

I am in chicago visiting for a superbowl party I need my car to start to get home to indiana. It cranks but does not turn over. I kept cranking it then eventually it would like die after about a minute and start just clicking. I do not know that much about cars and am stuck here and its very important I fix it and get it home. I have pushed it in a garage not sure what to do next. I just got the battery last year so I think its good any suggetions or ideas on what I should try next I am up for anything. 93 bmw 325i
Thanks,
joe
