Everything is included in this Kwikset that is needed for installation. The handle set is heavy and is made from high quality materials. So it will last a long time, but is backed by a warranty if something should happen. The smart key feature comes in handy as it allows you to "re-key" this door lock with other ones from the Kwikset family of compatible products. This way you don't need to get keys made or have extra keys on your key ring. It does take some work to do this, but its not overly complicated. We are beginner to intermediate DIYers and took around an hour to complete. Instructions were easy to follow and installation templates were also included. A drill was needed and a screwdriver as far as tools go to complete installation. The brushed nickel finish looks great.
