Undo the 4 M8 nuts that support the outer steering column - 2 near the top, 2 about 8-10 inches further down. With these removed, the outer column, to which the steering lock is mounted, can slide towards you by about an inch (effectively, the making the inner column shorter) and you can then tilt the steering wheel, top towards you, to remove it from the lock teeth.
