This is one of the coolest home security devices on the market! Started on Sharktank, this product is killing it in the marketplace! I’m going to buy one of these for my house soon and see how it works. It connects through your bluetooth if you happen to lose your keywords no worries, they will automatically unlock it from your phone! It’s super cool and I can’t wait to try this thing out. Kwikset is revolutionizing the security industry.
