Put this lock on my door after we remodeled our downstairs. All 3 kids are in high school/college and it is so easy for each of them to have their own code and no longer have to carry a house key. Also great for when you are gone on trips and can give a house sitter or pet sitter a temp code that works just while you are gone. It also easily connects to Ring & Alexa so you can check the status of your door from anywhere.
