Today I thought I'd take it out to the garage and tap on the lock body with a hammer while trying to turn it. I picked it up, decided to try it once first, and it turns and opens just fine. So I put graphite in the keyway, and turn it repeatedly without the shackle.

Then I did a search and read your post. I put the shackle on, and now it won't turn again. Turns without the shackle, but not with. I thought maybe I didn't have the shackle seated, but I did. So, I sprayed the crap out of the deadbolt mechanism with Teflon Multi-Lube, and cycled the lock repeatedly. Then I put the shackle on and so far it works just fine.

This was incredibly frustrating when it happened, and I'm still not sure I trust the lock anymore, but at least if failed while unlocked, I guess.
