Retrofit Kit for 663 Thumbturn in Polished Chrome
Can I get the 660 Single Cylinder Deadbolt with a SC1 keyway?
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.

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.
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.

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?
In order to better assist you with your deadbolt question, please contact Kwikset directly at 1-800-327-5625.

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
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.
