Locked mine in once by placing the key on the rear bumper and shutting the tail gate .It jamed the key in there and locked the doors at the same time.
I tried for a while then called RAC. One of there guys tried for hours then called for back up, his mate helping him tried for another hour or so and then they gave up and called a lock smith.The locksmith got in by making a key .
The d2 is very hard to break into , there is sheilding every where.
I am careful to not place my keys on the rear bumper while packing the car now.
