I may be wrong but BMW assist doesn't open doors. I appreciate how trumatic this must have been. So here's a suggestion. This issue can be prevented by doing what many of us have done and thats hide a key outside of your vehicle that can be accessed during this kind of emergency. Do it today.

And no i won't tell you where i hid mine.
