    Happened to me with a Kryptonite, but luckily with the lock only on the rack at work where I leave it, not on the bike. I looked into it and Kryptonite suggests what others are saying, but it's still there on the rack years later because I would never trust it again since who wants to not be able to readily unlock their bike? So I'd say, if the lubrication solutions don't work, just cut the lock and get another one.

    ETA that if you need to do this, a carbide grit hacksaw blade would be needed; a regular blade would likely not be up to the task.

    I had this problem with that brand of lock--it was like the tumblers themselves got out of alignment. A couple of times, it took upwards of 20 minutes to coax them back into alignment. What worked was keeping the key in and jostling the cylinder, even some tapping against a hard floor.

    I have a bunch of different U-locks (Abus, Krypto, On Guard). Even though they're more expensive, I've never had an issue with Abus. I've have had the stuck lock issues with my Kryptos and On Guard. I did the lube drenching methods to unstick them, but it's always a PITA.

    My Abus makes me nervous. Many times I will turn the key and the lock will not disengage. Sometimes it takes 3-6 retries to get it to unlock. I've noticed that it tends to be worse when the crossbar is below the U, so I'm careful when I lock it to put the U below the crossbar. I am actually afraid that one day I will not get it to open for me.

    My Abus is can be sticky -- the channel cut into the ends of the U has right angles. It makes the cylinder easier to bind up. Other locks the channel has rounded edges and is more forgiving (and easier to defeat with prying, maybe?). I'm a fan of using T-9 in both the U-lock holes and the lock cylinder. I do this proactively a few times over winter or after it's been in the rain a couple of times.

    My Abus has never had a problem and is the cleanest working lock I've owned, but it stays on a bike in in the basement so doesn't get jostled so who knows. I did have an OnGuard that was like Crickey's that I stopped using since it was a PITA. I seem to remember part of their marketing was that if it was hard for you to use, it would be hard for a criminal to pick. Whatevs on that.

    My Abus had me scrambling at 11 pm, latched to a pole in Seven Corners. Took 30+ minutes to open so I could ride home. Into the recycling bin it went, just too risky. My current Abus works great, though I've only used it for two years thus far.

    OK, so this goes to show that we all have had unique experiences with our locks. It was extra scary when 3 of my Krypto New York/Fahgedaboutits (1 U-lock and 2 chains) would not release the cylinder body from the U, even though they were fully unlocked. I had to get a rubber mallet to bang them off because they were so tight. My theory is that with those locks is that tolerances are tight and they bind more easily, but also the locking mechanism gets bound up inside so the little nubs that grab the U in don't want to move. Like others, I'll drench it in Tri-Flow.

    I lost the cylinder for the big U-lock (stupidly drove off with it sitting on my hitch rack and it fell somewhere on a bumpy gravel road). I use the chain ones semi-permanently on my car's rear hitch rack, so I don't need to open them much.

    Thanks again to Casey for bringing me the graphite at PY, when he had yet ANOTHER civic meeting to attend and so could not even stay for the presentation.

    Sadly, the graphite lube did not help, nor did WD-40. I may try spending more time trying, but I don't think that will work.

    At this point I need to saw through it? (A locksmith would be wimping out? And what would they do?)

    What kind of saw do I need?

    Did you try your other key? I've had a problem with a key being bent. Seems your problem is getting the key into the keyhole. Perhaps something got inside the keyhole?
