the good news, we finally made it into the car. yeah!!!! i am so amazed at how bullet proof these cars are. we tried the battery method, which got the lock open halfway, but not fully. so my husband, who mind you is 6'5" and over 250, managed to get his head and arm through the small hole in the backseat. he jerry rigged a broomstick with a hook on the very end, and managed to get it hooked around the front passenger door lock. he couldn't get enough leverage to pull up the lock, so i stood outside the door, with the key in the lock, and pulled up on the handle and turned the key clockwise at the same time, while he pulled up from inside, and low and behold the lock moved just enough to open the door. so needless to say, with a little ingenuity and a whole of peserverance we were able to succeed. i couldn't imagine what we would of done if this hadn't worked. as for the hammer method, he tried breaking the little window in back with a hammer, he hit it as hard as he good, only thing it got him were some lovely scratch marks on the window. it's great to know that bmw makes such great cars, but at the same time a little scarry that you have work so hard to outwit them. thanks for everyones input, we appreciated it.
