    Rated 5 out of 5 by from palazzo This lock works perfectly. The only problem we had was that the brass pitted and looked old and discolored. I called the company and a wonderful agent created a claim after looking at the pictures I took and happily advised me that they would send a replacement for both the handle lock and the deadbolt ( both of which were pitted). I received the new locks and installed them easily and they look brand new. This is a wonderful company to purchase from. I would recommend them to everyone/

    Rated 5 out of 5 by from My dead bolt lock would no longer work with my key. I re-keyed the lock with the smart key that came with my lock set, but the re-key effort would never remember the key. I called Kwikset and talked with a very knowledgable rep (he was very well spoked and easy to understand) - I apologize for not remembering his name, I think it was Alex? Anyway the replacement lock came on time, as promised by Kwikset, I am very happy and impressed with your service! I have been using Kwikset (smart key) on all my doors - house, garage, shop and also in my prior house, I shall to continue to buy your product. Thanks, your customer rep made it all happen.
