But I WAS missing something. You can use the Hex Wrench that comes with it to loosen and rotate the silver part (which I think is actually called the 'spline on the shackle'). So this lock mounting thing is not a problem. Go ahead and buy it. No extra tools or anything are required. I totally take back my bad review. I'm still only giving it 4 stars because they shouldn't sell it with the shackle tightened in a position that isn't useful to anyone.
I looked at Kryptonite website to hopefully get the lock replaced but they seem to only have a guarantee of the bike is stolen and you need proof of sale for the bike. Silly because for me and a lot of other people I bought mine with cash on Craigslist.
Worked well until it was cut
Another suggestion... loose the quick release on your seat. It's hell having to stand and pedal if they steal your seat. Don't make it easy on them.
Con: I often have to fight to get the lock open.
You'll also read a lot of reviews about this thing being broken. The thing is nowadays there are mini tools that can cut through just about anything, and quickly. I view this thing as more of a deterrent than a 100% full proof lock. Therefore I've used this lock combined with a thick chain lock to keep my bike secured in downtown Fort Lauderdale, and at the beach. It's always been kept outside. To put that in perspective, when I moved to the beach 4 out of 5 bikes were stolen from my building in less than 2 months... mine was the only one that wasn't. To be fair, I noticed most of the bikes had minimal security, such as small basic cable locks only, which were quickly cut (most of them were taken during the day!).
Another thing is that where possible, you'll want to keep the keyhole pointed downward. I had his thing in the rain for so long with no issues, but one time the keyhole was pointed up and a heavy rain came through, and it was full of rust and pouring out just the same. Nevertheless, it's still held up and still does. But since the rain I've had the occasional complication with the lock mechanism. All in all, for the price, this is a great lock in my mind.

This lock worked fine for about a year with regular use. Then the cylinders inside the lock mechanism began to stick unevenly, preventing me from inserting the key all the way in. Read morePublished 15 days ago by Suzita Cochran
