My 1997 BMW 740i had the parking lights left on over night, so when I got in the car I assumed the battery was dead when it would not start. I tried jump-starting it and turned the key a bunch of times and I think that set something off with the CODE security function. I am not sure if it was asking for the code beforehand, i wasnt paying attention. I then called AAA out there and they checked every reason why it should not be starting and everything was working fine. So I am assuming its this CODE issue. I bought the car from a friend and since its a 97' im sure it has had a lot of owners and no one knows what the code is. Im freaking out because it just wont start and I dont know what to do. Can anyone help? AAA guy also tried disconnecting the battery and then reconnecting it and seeing if it would start the car then, and it still didnt. Please help me!
