I'll never buy a Kwikset deadbolt!
Long story short, I got locked out of my apartment for over 2 hours last night. The 6 month old Kwikset deadbolt wouldn't turn all the way. While waiting outside I googled some stuff and came up with people saying they were junk. When the 3rd locksmith I called showed up, he said these were junk and he's always responding to lockouts for these. He recommended Schlage locks. I close on my first duplex in a month and I'm going to look into changing them if they happen to be Kwikset locks. Anyone else have issues with these things? Turned a crappy situation last night into a learning experience.
