Meet the secure, tamper-proof lock from Nest and Yale. It's keyless, so you can lock and unlock the door from anywhere with the Nest app. Give people you trust a passcode and get alerts when they come and go. And lock the door with a tap. If you forget, the Nest x Yale Lock even reminds you. The Nest and Yale Lock connects to your Wi-Fi and the Nest app through the included Nest Connect. Some features, including mobile alerts, remote control and custom schedules, require the Nest app, working internet and Wi-Fi, and Nest Connect or Nest Guard.
