  • Rated 4 out of 5 by from Works well. Was reasonable easy to install, and rekeying with the smart key feature was fast. There were a few minor problems that seem to stem from the existing holes. On one door, the problem was our existing hole was not drilled in the correct place, being about 2 mm off. (The old lock could slide around a bit to compensate, while this one required the hole to be more accurate.) Used a Dremmel to shave off a bit on one side and this lock still covered the hole just fine. On another door, everything fit together fine, but once the screws were tight the key was nearly impossible to turn. Eventually I was able to tweak the alignment so it worked fine.

    Rated 5 out of 5 by from Great Service, quality and prices. We ordered all the Qwikset door hardware for the new house we were building. Prices were great, quality was great and they look great going up. Our trim carpenter loves Kwikset as he can set the bottom outdoor locks to one key and keep one aside and change them all to a different key when we move in. They shipped quickly and our order was correct. Much less than the big box stores for the same.

  • Can I get the 660 Single Cylinder Deadbolt with a SC1 keyway?

    Asked by: prettyplease
    Hello prettyplease, Thank you for your interest in Kwikset 660-15A-SMT. The lock is a Smartkey lock and may not be modified to fit a SC1 keyway. Thank you, Kwikset Support Team

    How can I get the thumb lever to be horizontal when the door is locked? I had that on the previous Kwikset but can't figure out how I did it for the new one. All other deadlocks are horizontal when locked. Thanks.

    Asked by: Almower
    Hello Almower, Thank you for your interest in Kwikset model # 660-26-SMT. We apologize for the inconvenience you have encountered with your lock. Unfortunately, there is no other way to alter the lock. This is how it is manufactured. Sincerely, Kwikset Support Team

    I have a commercial grade door with a cylinder lock that isn't a straight out dead bolt, but comes out as a hook, will this work or if not do you have a smart key product that will work?

    I am an apartment manager and I upgraded all my locks on the property to the Kwikset 660 15. Unfortunately, for some of them the original key has been lost, is there any way to re-key them without it? I found manuals for different models, but not this one

    Asked by: Calin
    Hello Calin, When re-keying a SmartKey lock the first key used must be the functioning key. Since you do not have this key you can take your cylinders to your local home improvement lock department. They should have a SmartKey resetting cradle for your cylinders. This cradle allows the lock to be re-keyed with out the original functioning key. Thank you, Kwikset Support
