Only Key Locked in x5 - need help

[kcoolarrow]

Hello everyone, I own a 2003 X5 bought used ..came with one key, which key is now locked in the vehicle as I was unloading some stuff from the back of the vehicle without unlocking or disarming the side doors. Closed the back up not knowing key was in there and now I am stuck and don't want to have to break the little window. Also, I live on a ranch, 70 miles from the nearest city and dealer.

Researching the forums yesterday before I could post, there appears to be a way to do it - but nobody will state it publicly. I respect that.

Your help is much appreciated in advance.
