Yesterday, I had a meeting at 4:30, and I planned to get there on my little Raleigh folder, which was locked in the nearby garage. I left the office with 45 min to get there, plenty o time. Except when I got to my bike, the cylinder in the ulock was frozen. I had just locked it there in the morning, so this was inexplicable. I fiddled with it for 5 minutes or so, figured it would be worse to break off the key, so I double timed it on foot to the South Side. So frustrating. Fortunately I was wearing a wicking golf shirt or that would have been ugly. Made it only 10 min late and everyone was gracious and it was fine.
I came back this morning with a can of WD40, pumped the cylinder full of oily goodness, and it opened instantly.
The moral is, if you use your lock all the time, and it is out in the weather, or just over time, shoot some light lock oil or something in the cylinder every so often. In fact, when you lube your bike, do the lock too, think of it as part of the bike. Those little precision plates do not like to dry out. Save much cursing, if that is a goal.
Kryptonite actually recommends WD40 as a cleaner/degreaser and then some waxy Teflon lube (which they suggest may be found in, say, a bicycle-selling establishment) every month or so: in other words, treat it kinda like a bike chain. Convenient.
And now I realize that I have not done this in months. Oops. Thanks for the reminder.
for the last few weeks, i actually found that saying ‘come on, you son of a b—-‘ got my lock to work. she got tired of the abuse and stopped working. i was just about to head outside to clean n’ lube the bike, so i’m glad i read this! good ideer.
My main lock was giving me a lot of resistance lately and though I kept using it, I was afraid the day would eventually come when I was just stuck with (a) a bike perma-locked down somewhere or (b) a useless lock. Rather than trashing it, or waiting for a crisis and looking for an angle grinder, I dropped a few drops of lubricant in the other day, and within a minute it was working good as new! My belated thanks for the tip/reminder.
My iphone mic stopped working and the phone was only useful via speakerphone or headset. Then I threw it in the freezer for fifteen minutes and now it works fine! Thank goodness I tried that before resorting to WD-40. :D
as for u-locks, they make great replacement horse-shoes. But seriously… I have nothing to add. Glad you got your lock off without resorting to more destructive methods.
