you will need to pop the hood open and jump the car at the jump points, that is how you get the power to the trunk as well as the rest of the car

My battery is located in the trunk, where are the "jump points" located at under the hood if the battery is in the back? (Sorry if I misunderstood you)

I'm not a BMW guy but I have seen the lighter being used as a jump port, there is this little charger that plugs into the lighter or power port and slowly charges the battery, now I realize that if the battery is totally shot the charger just won't work but it might supply you enough power to pop the trunk release.

Under the hood you should find a bolt covered with a black cap with a + on it, it is right in the middle of the intake ports of the manifold - that is the positive side, any other ground point will work for Neg

Yes, charge the battery or jump the car using the under hood battery terminals, or you simply have to twist the key in the trunk a bit harder to the left until key is horizontal to unlock it manually.

Thank you guys for all the great info, I will be troubleshooting today. I appreciate the assistance
