Yale knows secure locks. Nest knows the connected home. Together, we've made a tamper-proof, key-free deadbolt that connects to the Nest app.1 Now you can lock and unlock your door from anywhere. Give people you trust a passcode, instead of a key. And always know who comes and goes. When the Nest Yale Lock is connected to the Nest app, you can unlock your door from your phone. Create passcodes for family, guests and people you trust. Even set times when passcodes expire. You can get alerts whenever someone unlocks and locks the door. And when Nest knows you're away, your door can lock automatically. RB-YRD540-WV-0BP
