(This review was collected as part of a promotion.) What a great lock!! To my surprise it had easy directions to follow and I got it installed all by myself. It definitely made life a bit easier now that my kids all have a way to unlock the door and no keys are being lost. My 5 year old now knows how to unlock it which make my life easier when I have my harms full of groceries bags.. we definitely feel safer. I definitely recommend it to everyone.
