Common problem and will probably nessesitate replacing ignition switch barrel and steering lock, you will have to remove upper and lower steering covers and lower steering column to lowest position to allow you access to the two shear bolts which hold the steering lock assembly to the steering column, your local bmw agent shoul be able to get you the parts to allow you to use your own keys.
