if you are sure its broken, you can hope it broke at the interior handle side, and not under the hood.
if it broke in the inside of the car, you can find the cable and just pull it with some pliers or something to get it open and fix it. that is if it broke close enough to reach. otherwise....I havent a clue how you would get it open.
