Try giving the shackle a good rub with emery paper if it's corroded and then oil the whole thing heavily. Let it sit for a few days and wipe off the excess. Should last forever really. I lube my lock as part of servicing the bike. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=12927#post-155824 Wed, 04 Jun 2014 11:47:25 +0000 dg145 155824@http://citycyclingedinburgh.info/bbpress/ <p>Hi</p> <p>I have a Kryptonite Evolution 4 Series U Lock, which I keep at work. It's spent the last year hanging in a covered bike cage (there's a roof, but otherwise open to the elements).</p> <p>It's started to get quite difficult to open - not the lock mechanism itself, but separating the U-bend bit from the handle once it's unlocked. I've tried spraying all the connecting bits, and the lock mechanism, with GT85 but to little effect.</p> <p>I'm a little worried that one of these days it's going to be completely stuck, locking my bike to the stand.</p> <p>Any ideas for a solution, or is it new lock time? </p>
