Please help! Today on way home to Jacksonville from Key West when I stopped to fill up with gas I couldn't turn the ignition switch all the way back to the lock position, the car also makes and extremely long beeping, much longer than if I just get out of the car with the key in my pocket. Also, I am not able to lock the car at all. When I try to lock it manually the doors just automatically unlock. I'm heading to the store now to get a replacement battery. I sure hope that works. Thanks a lot!
