Rated 4.4 out of 5 by 39 reviewers.
Rated 5.0 out of 5.0 by An excellent product!! Have found since Kwikset came out with the Smartkey product, the ease of installation and keying has become a lot easier. While I'm not a professional locksmith, I've installed over 40 of these deadbolts and entry sets for myself, friends and my church. These are well proven locksets and I will continue to recommend them to friends & buy and use them. This deadbolt was purchased & installed for a widow who is a family friend. July 21, 2015
Rated 5.0 out of 5.0 by Easy to install, and seems to be solid It was easy to install; and I've received compliments over how much better the simple change has made the view. May 5, 2015
Rated 4.0 out of 5.0 by good quality I bought this deadbolt to replace my old one and it fit perfect. It seems to be well made and had it installed in 15 minutes. January 10, 2012
Rated 5.0 out of 5.0 by Quality sturdy, practical and a quality product which saves money for not having to pay for a locksmith. March 25, 2014
Rated 5.0 out of 5.0 by Replaced 15+ year old Deadbolt Was happy that this style was still available after so many years... the internal housing changed some so I just used the old internal in place of the new and all worked out (used the old outside external housing also so it still matched the aged outside door handles) ~ love the SmartKey ~ worked perfectly ~ with so many family members having the old key it was a life saver ~ OK... that's going a little to far but it is a much appreciated feature/benefit!

Rated 3.0 out of 5.0 by Fits requirement; key requires "jiggling" to open the lock The smartkey is a good feature and that is why I purchased this lock to match others smartkey locks. However, this particular lock is sensitive to how far the key is inserted (won't work all the way in like the other similar locks) so it is in a door that doesn't get used that much. I've not had this problem with any of the other locks with the similar key. April 25, 2012
Rated 4.0 out of 5.0 by Easy to install I bought a Kwikset deadbolt to replace the one I had. I wanted to update the color and to match the lever I installed. It was easy to install in the holes that were already there. I did have to rout out the hole on the door sill to accommodate the bolt, but after that, all is just right. June 5, 2012
Rated 5.0 out of 5.0 by Quality low cost dead bolt with smartkey option Product was at a price point that allowed a small profit along with having the higher end options such as smart key that made the job go easily April 25, 2012
