          Great product!
          [This review was collected as part of a promotion.] Kwikset 660 deadbolt, Keyed one side ,featuring Smartkey security in Satin Nickel featuring Microban is a great product. I absolutely love the satin nickel finish! The Microban feature is such a great idea! It is 99.9% cleaner than the typical lock. I had never heard of a smart key before. It’s a lock that you can rekey yourself in seconds. I highly recommend this product!
            Easy Installation
            [This review was collected as part of a promotion.] This Kwikset deadbolt lock is such an easy installation with easy to understand instructions. I love the easy smart key, you can easily rekey to fit an existing key you already have so you won't have multiple keys to unlock your doors. Nice satin nickel finish and the lock glides smoothly.
              Very solid lock
              [This review was collected as part of a promotion.] I love using this lock I feel very safe and secure in my home with this lock and the installation was so easy for me I would definitely recommend this lock
                Probably would work better on a newer door
                [This review was collected as part of a promotion.] We have an old house and had difficulty getting it to fit on our door. It would probably work better on a newer door that's not warped. But love the technology.
                  Perfect upgrade
                  [This review was collected as part of a promotion.] Ive been needing to replace my front door deadbolt and this opportunity came at the perfect time. My husband replaced it with no issues. Its great quality and very durable. I recommend this product to everyone who needs a secure dead bolt.
                    Easy to install, works as it should
                    [This review was collected as part of a promotion.] The lock is sturdy and looks great on our door. Installation was not hard at all. We have not had any issues and would recommend to the next customer.
                      [This review was collected as part of a promotion.] This is a wonderful and perfectly functional door handle. I love the smart key security feature and that it is in a satin nickel and has microban! Perfect for my home.
                        Easy to install and very secure
                        [This review was collected as part of a promotion.] I replaced my existing dead bolt with this one because my key always sticks on the old one. It was so easy to install and the directions were easy to follow. It matches my lock perfectly and seems to be more secure then the dead bolt I had before. The re-key option is great and also really easy to do.
                          Not an influenster
                          One I figure this product out, I’m sure its good. Problem is and what nobody will tell you. If you follow the written directions and somehow turn the key incorrectly. You will have no working keys and a paperweight. I’ve tried two and continue to have issues.
                          Response from KwiksetOct 20, 2023
                          Hello Bravogolf,

                          It sounds like the key cylinder is not reading your key correctly. We recommend following the cylinder recovery instructions in the link below. If you can get the key to turn, you can then re-key the cylinder with the SmartKey tool to the same key.


                          If the key is still not turning in the cylinder, please contact our Support Team so we can help you with the right solution: https://www.kwikset.com/support/customer-service

                          Thank you,
                          Kwikset kwikset
