Kwikset 660 Single Cylinder Deadbolt featuring SmartKey Security in Venetian Bronze

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.

new kwiksets not easy to install i'm replaceing old kwikset with new ones these don't allow for any leeway at all !!!!! where old ones were adjustable and very easy why change a good thing???? ya need to make your products for average homeowners!!!

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 am very happy with my new Kwikset 660 Deadbolt, Keyed One Side, featuring SmartKey Security™ in Satin Nickel featuring Microban. Installation was extremely easy and didn't take very long. I love that it has SmartKey Security. It was very easy to rekey my lock to match the key I was already using. I definitely recommend this Kwikset Deadbolt. I love it!

What happened Kwikset, you changed the design? bigger cylinder screws with the same cylinder hole as old which is not the right size. The screw won't fit in the cylinder. The nice people at Lowes looked at it to and thought either the wrong screws or the wrong cylinder went into the package. I am not abandoning Kwitset but this was a surprise. Open the box before you purchase and look and see if the screws go through the cylinder before you buy.

[This review was collected as part of a promotion.] We built our house recently and it's bothered me that we don't have a deadbolt on our door from the garage. I was so happy to try this out. It was fairly easy to install and matches our current hardware. Easy peasy!

[This review was collected as part of a promotion.] We needed this so bad my husband really surprised when he see it. I've been asking him for years we need new one finally just surprised me that I will get this. Thanks a lot Influenster I really like it the best made our door looks way better.

[This review was collected as part of a promotion.] I have had a chance to change out my lock yet because I need to get a matching door knob but already it tried using the rekey option and it is really a neet option. I will be replacin all my locks so I can have the option for shared keys on specific doors. I like knowing my side garage door can share the same key as my deadbolt.
