Thanks for the reply. I had the lock assembly out and in my hand, the key only has two positions. Completely dissassembled, cleaned and lubed it. Didn't see anything broken. The key cylinder can only be removed with the key in the "ignition on" position, can only be reassembled with key towards the steering lock position. After turning to "off" or "on", absolutely will not turn back to steering lock. I'm sure its either a fault with the key cylinder itself, or the key is too short to engage the last pin (the one that holds the cylinder in the body of the assembly). Even if I am able to repair it, will probably never use it. Hate for the thing to fail in the locked position.
EDIT: Had the local BMW tech look at my lock. The key is worn down so that the pins (little flat blades, actually) don't go down flush with the cylinder. Not a problem where the barrel is worn to match, between "off" and "on", but the seldom used fork lock position groove is sharp-edged, and would catch. Filed down the pins flush, all is good.
