LOCKED out! HELP
 

I left BOTH my keys for the CLS in the trunk/boot, and disconnected the battery.
I left the doors and everything UNLOCKED.
I came back from a trip...
I can open the doors, BUT NOT the trunk/boot of the car. I even try the lever inside the car to open the boot/trunk.. but it DOESNT!
the fuel cap DOES open.. but not the TRUNK. And i cannot start it or do anything as the keys are in there. what CAN I DO?
