Kwikset 660 Deadbolt-Keyed One Side-Pin & Tumbler in VB

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 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.

It Was So Easy To Install. At First I Didn't Think It Would Work Since I Live In A Mobile Home But It Worked Perfectly.

[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!

[This review was collected as part of a promotion.] This took under 5 minutes to install. I actually use this smart key system from Kwikset through my entire house. Being able to have 1 key for all outside entrances is great! I have 3 outdoors on my second level and this balcony on my second. Saving money buy making copies of 1 key instead of 4 makes me happy. I want recommend again and again

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.

I bought this deadbolt for a door leading to our garage. It did require drilling the holes for the door, and I found the drilling and assembly instructions to be very good, though on my computer I could not make a paper copy of them that wasn't postage-stamp-size without losing some of the steps. The online hole-drilling guide, however, was perfectly-sized when I printed that. My door was 2 1/4". I was able to buy and receive the deadbolt itself online within 48 hours, but could not find the "thick-door-kit" anywhere, and even through the most famous online retailer, I had to wait a miserable 2 weeks for it to arrive. Why??? Otherwise, a fine deadbolt.

[This review was collected as part of a promotion.] First this kit has easy installation instructions for even the most novice of DIYer. Only requires a few basic house tools to swap out from an existing deadbolt lock. The satin nickel finish is prominent and sleek and looks great on any door you are adding this too. Textured finishing on the turn lock adds a nice touch of variety in design. This product apart is simple yet when fully installed is tough will add peace of mind of security for your home.

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.
