My driver's side door will not open from the outside. It is not locked and will open from the inside.
How to open driver's side door on 1997 BMW 528i

Take it to a mechanic for repair. Door handle or linkage problem.
I agree with pushrod, you will have to take the door panel off to see if handle is broken or the rod has come off if you are fairly mechanically incline you could probably try it yourself if not I would take it to a mechanic
