Had on door for years. Worked great, but finish was losing its polish. Was able to live with it since front door gets a whole lot of sun. Then the unthinkable happened. The lock and/or cylinder stopped working and was locked out of house and figured a piece of glass would be cheaper then calling a locksmith. Anyhow, had to remove from inside and purchase a new one, 1/15. Hope this one lasts longer. Didn't realize had lifetime warranty. Will be calling Kwikset to check on warranty.
