I already have a disc lock. I used that with the steering lock just to be safe, especially when parked in Oslo for longer periods (over night etc). But now I just take the disck lock with me. I proably will replace the steering lock sooner or later, but for now the disc lock works great. (it's on of those types with a 100 dB alarm built into it). And I no longer live in Oslo (moved to a city a hour ride away) so it's safer in my garage overnight etc.
