Huckster, I've been having misgivings about recommending the armoured cable lock from ABUS. Clearly they are not as strong as u-locks. Since this thread does help inform on security, I've decided to now delete that lock, and its genre (in a few minutes). I can only see it being useful to couriers, who will only be away from their bikes for a couple of minutes.
As for your other question - it appears that though the key combinations to Onguard locks can run to 100,000 or more, it would appear that similar keys to locks have been found, from other similar locks, and they worked. This is either an extreme coincidence, or the amount of variations to the key isn't as great as it would first appear.
