    Rated 5 out of 5 by from KWIKSET stands behind their product I purchased these for my home back around 2005 and have been thoroughly satisfied with them. As with any mechanical device, they will wear out when used often but, Kwikset stands behind their product 100 %. I would not hesitate to buy from this company again and again.

    Rated 5 out of 5 by from Good Lock, Great Service I bought my Kwikset lock 12 years ago. Earlier, this year, it started to "hang" and would not unlock without jiggling the key. This process could take several minutes. I stopped locking the lock, which was on the outer door and only locked the lock on the inner door. I called Kwikset support and let them know. They had me take a picture of the lock and email it to them. I did. A replacement lock arrived a few days later. I believe in Kwikset locks!

    Rated 5 out of 5 by from LIFE TIME WARRANTY!!!!!! I have been using Kwikset door sets for many years. They are reliable. It is peace of mind with a life time warranty when there is an issue. It is fantastic when a company stands behind their product. Thank you!!!!

    Rated 5 out of 5 by from The finish bright, high quality Bought these deadbolts to replace 15 year old Kwikset locks that were very worn. the finish is high quality and they were easy to install. What made me buy these and door knobs to match is the Smart Key technology. I installed new hardware on 4 doors and keyed all locks to my current key (8 locks total) myself. And it was easy using the provided instructions and tool.

    Rated 5 out of 5 by from Great service and warranty. I bought this product 4 years ago and then the lock mechanism jammed in the locked position. I contacted customer care and they asked me to submit a picture. I did this and then was told that it would take a week to get the new lock to me. They also said they would be sending a different finish product to me asap so I could lock my house. They stand behinds their product and care about the fact that if your lock is damaged you need it fixed quickly!

  • My existing key won't fit, any suggestions? are some keys incompatible?

    Asked by: lavy
    Hello lavy, If your house keys are Kwikset compatible (KW1 or KW10) keys then you can use the SmartKey technology to rekey them. SmartKey products can be re-keyed at the consumer level by following the re-keying instructions but is not compatible with other brands. Sincerely, Kwikset Support Team
