I bought Kwikset locks for my entire house in 2001 (12 years ago).They're all gone bad.
Most of the time, it's the finish. The front door lock finish has simply rubbed twice over time... twice now! They replace them, sure, but you have to take the time to install the lock or hire a locksmith.
It's not worth the trouble, folks. Get a good luck for just a few dollars more and never worry about it again. What a terrible company and product.
I just got off the phone with customer service. I asked if they'd replace my lock with something better this time.
He said it would be the same product, and that "nothing has changed." I guess in 3-4 years I'll be replacing it yet again.
Monetary Loss: $130.
