Sounds like classic ignition barrel failure..thats extremely common and well known on all BMW's of that era...so i dont think its anything you have done...you could try spraying some penerating oil into the lock and see if that helps..or with the ball pin of a small hammer try tapping the outside of the lock..if that still doesnt work then im afraid its new barrel and key required..I do hope this helps
Im afraid so unless you have good reputable mobile mechanic in your area to come out and do the job for you..that might be something to look into to save ona towing charge
