Got in my 535i yesterday & the ignition key won't turn past the steering lock. The key slides in freely & turns slightly until it hits the lock but thats it. I've tried jiggling the steering wheel & turning the key but no joy. Since you can't turn the key the ignition lock assy can't be removed & I pulled the switch assy off the other end but that doesn't reveal much. Is there any way to access the actual s/w lock mechanism externally? It seems to be hidden up inside the cast housing and I'm running out of ideas.
