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.] 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.] I received 660 dead bolt keyed one side featuring smartkey securityin satin nickel featuring microban, two weeks ago, we had it completely installed in less than 10 minutes 10/10 recommended. My family will definitely replace are other dead bolts with same product.

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.

Great value for the money. Polished chrome looks great in renovated kitchen door. Would have been an easy install except that after several attempts to insert the D-shaped spindle I found a large shard of steel blocking the hole. Had to punch it out with a screwdriver and file rough edges. See photo. Not a deal breaker but you might want to have a talk with the QC dept.

[This review was collected as part of a promotion.] I have bought a good many Kwikset Smartkey combo packs for our house and rental properties. Having the Smartkey feature is a real plus for rental properties,we can give the new tenant a new key. I have only had one tenant that I know of that I think changed the key on me.

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.
