Ok, here is a strange one. I work out of town weekly and since I have a rental for my job, I haven't driven my Grand Prix much. I started it every 3-4 weeks just to keep things running alright. Well, last month I went to start it and found that the battery had gone dead. I assume it is the winter weather in Michigan. I tried to open the door so I could get it out and charge it, but the key doesn't open the door. Apparently it is only for the ignition. Have I just gotten screwed by the dealership (I bought it used)? Is there another way to get the hood open so I can get the battery out?

Thanks,
Scott
