Back in reality, if you need the key to unlock it to get it off, then also needing the key to lock it is trivial. I second what the other guy said - requiring the key to lock it means no one ever locks it then realizes they forgot the key when they go to unlock it.
Right! I have a couple of Abus chains with integral locks. Theu do not require a key for locking and I normally carry one in a trunk bag, unlocked. At least once I almost locked the bike up with my key sitting at home. Fortunately I checked my pockets for the keys before locking the bike up with it. Could have been a long walk otherwise.
One advantage of most european frame mount ring locks is the key cannot even be removed from the lock until it is locked, immobilizing the rear wheel. That pretty much idiot proofs them. The key is certain to be with the lock except when the lock is locking the bike.
