I have a 2008 BMW 328i. I took the battery out to check if it was good but I locked myself out of the trunk so there is no power to open the trunk now. I tried jumping power under the hood on the terminal posts but that does not give any power to the electrical system. I tried using the key on the key fob to open the trunk but the trunk lock will not open. Can any one help? One site mentioned breaking the tail light.
