I havent followed this... did you get in?
I locked myself out of my 240td 2 weeks ago (left key in ignition with engine running; that's what my locking system calls the self-close now position).
Anyway, this works with most vehicles w/o power windows... you just need you (and maybe a freind) to push inwards and downwards firmly on the window glass with the flat of your hands... I guarantee you that with most (older) cars you try this on, one or more of the mechanisms is gonna just let you ease the glass down with no drama, nothing broken, no sign of a forced entry and no tools/damage. Stealing cars is a natinal sport in England...
