That's right Any lock will have troubles moving between room temperature and severe cold just from normal condensation. Lube it. Today I tried Sonax, which according to the sticker is exactly what one should use in this situation. It said it was inflammable - probably alcohol in some variety. Didn't work. Boiled water on the other hand worked two times. But it sucks having to do, obviously. And the situation will just reoccur that way. No, one should have a big key, a big keyhole, and a lid on the lock itself. Try rinsing with alcohol or some other solvent to remove all the oil and then use it dry in the cold months. One assumes that at (did you say) -6 degrees (C) there is little chance of rain :-) I usually use dry graphite powder to lubricate locks. But I doubt that makes them impervious to moisture from condensation. I've never had a bike lock freeze up, but in freezing weather, I've almost never had to lock the bike outside. I remember way back when they used to sell graphite power in a little squeeze bottle with a long especially to lubricate auto door locks with. Like a lot of other things from my youth, "you don't that any more" :-) Hmm. Maybe store the lock in a plastic bag with some desiccant powder? It would be a use for the little bags of desiccant that come in certain pill bottles. Or perhaps heat the lock to drive off moisture? Hub dyno users could rig up a little resistance heater, maybe using their stash of old halogen bulbs. Mega-lumen battery light users could cook the lock by holding it in their headlight beams for a while. Be careful not to hold it too long, or you might anneal the metal. -- Cheers, John B. Istill have a tube of powdered graphite that my dad, a Class-A auto-mechanic usedto use. Talk about premature nostalgia. I bought a squeeze bottle of powdered graphite about a month ago. Did you? what sort of shop? I think it was Home Depot -- a national chain of "home improvement" stores. Hardware stores carry them too. We have "Home Pro" over here which is probably similar. The next time I'm down there I'll have a look as my front gate lock would benefit from some sort of all weather lube. -- Cheers, John B. |

BBB-41 Powerlock Bicycle Lock
This morning the lock was frozen again!
Right now it is -4.7. But atypically, I hadn't used the bike for some ~24h so it is possible the temperature at some point went above 0 since I last used it. The situation was the same as the first time, i.e., it was impossible to get the key even 1 mm into the keyhole. This happened despite the two different alcohol treatments mentioned in this thread. The problem isn't the temperature in isolation but the miniature key and key hole, without a lid. This maybe works in the Netherlands (home of BBB) and China (place of manufacturing) but not here. What is needed is a lid, a big key and a big hole. -- underground experts united http://user.it.uu.se/~embe8573 |

I'd spread a very thin layer of grease or wax over a portion of the lock so your molded cover can be removed or peeled back a bit for key access. -- - Frank Krygowski |

No, I think I'll use this as my "summer" lock Interestingly, this is my first quality wire ever! But I do not doubt the quality in other parts of the world or in the non-winter season. -- underground experts united http://user.it.uu.se/~embe8573 |
