Kwikset 660 Sgl Cyl Deadbolt Featuring Smartkey Security™ in SC

It's a basic deadbold. Works great, we put it on our RV door.

Locked and secure, with solid construction.

I bought two new Smart key entry knobs with double cylinder dead bolts as a kit. Installation was simple and the smart key worked as advertised. Took about half hour to to complete both doors.

[This review was collected as part of a promotion.] I had a different lock on my door but didn't seem as heavy duty, this one seems to be made of really great quality and will last a long time, this was really easy to install and looks really nice on my door.

[This review was collected as part of a promotion.] Installation was very simple and only took 5-10 minutes. The directions are very easy. It looks great and matches all my other nickel hardware. I love the smart key security so I'm always at ease. It comes with two keys which is convenient for me and my husband. It locks very smoothly and looks great!

[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!

[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.

If you ever need to change your Deadbolt & key the Kwikset components are almost universal. This means that one can usually change out the cylinder and use all the old hardware and latch, the part that moves in & out. The Kwikset brand is especially handy for landlords that need to change locks quickly & often. Another bonus Kwikset give you is the fact that repair parts are often in stock at your local hardware, and the keys somehow duplicate easily & correctly. I can't tell you how many times I've had a key made for a different brand and it didn't work. Kwikset duplicate keys always work the first time for some reason. A little security tip; if you use a foot or so long piece of plumbers strap (metal tape w/holes) screwed along the wooden door frame (behind the molding) to reinforce the hole for the latch - it makes it very difficult to kick in the door. If you need keyed alike locks, the key codes are on the package. So you can match up as many keyed alike locks as needed.

Works great for 2-3/8" backsets. Does not adjust to 2-3/4", despite stating it does on the packaging. After a half hour trying to figure out the mechanism to adjust the backset length I called support and was told the model is not adjustable. I need a lock with a 2-3/4" backset and will buy elsewhere. A functional lock, but I'm disappointed in the advertising.

I purchase this deadbolt but when it arrived one of the bolts would not fit in the screw hole. The threads in one of holes looks like it is cross threaded and one of the bolts had been cut off but too short so I can't install the deadbolt. Even though I own several smart key handles sets and deadbolts I can not recommend this one. The quality control is just not there.
