I'd heard about and read up on these types of locks and decided I really wanted to try this one.  Kwikset is a brand I've known about for decades and is a brand I have previous experience with.  I was sure this would be an easy project, something I could handle on my own.  It was fairly easy to follow the included instructions and rely on some youtube videos.  It looks so nice and polished compared to the old door knob/lock.  One of the bonuses I love about this lock is that I don't need my key.  Nobody needs to have a key!  I can give each family member/acquaintance/worker a specific code just for them and not worry about who's coming in because I'll know that person.
