I needed to repair a lock at my Tucson rental property. I phoned the Kwikset support line and they answered immediately.  After just a few questions they determined the problem and shipped repair parts to arrive the next day.  When making the repair I needed one more part and that came express as well.  A great company is not simply producing great products.  As a manufacturer myself I know no matter how hard we try, every product that comes off the line is not perfect. But having a dedicated team of customer centric , well trained and knowledgeable support professionals, like Kwikset has, provides the necessary back-up that even the best quality control team sometimes needs.  Kwikset has it all and provides it all; fast, correct and gracious. [This review was collected as part of a promotion.]
