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.] There is not a while lot to be said about a deadbolt but I can say that installing was very straightforward and the options were pretty universal. Once it was installed then it was just a matter of re-keying it to use the same key as the other locks. This was also very easy and I appreciate that it is an option. The satin nickel color also matched my other fixtures perfectly. I can easily recommend this deadbolt to anyone.

[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.

[This review was collected as part of a promotion.] I LOVE this product! I was a bit skeptical when it said you can re-key your lock yourself. I was honestly worried about the safety of it all, but this product is revolutionary! I love how easy it is to install and the technology behind it!

[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!

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.
