Yale's Linus lock operates on the Works with Nest program, combining Nest's approach to the smart home with Yale's longstanding experience in lock security. The keyless touchscreen lock lets homeowners lock and unlock doors from anywhere, create passcodes with different levels of access for family members and guests, and receive alerts based on passcode use. In homes that take advantage of Nest Protect, the Linus lock can issue voice and visual alerts if smoke or carbon monoxide are detected. Linus can also tell the Nest thermostat when to switch to Home or Away mode based on user access, and can turn Nest Cam cameras off when people are home and on when they leave. The lock itself features reinforced hardware and bank-level encryption to protect access. If the home's power or wi-fi go down, homeowners can still operate Linus with the touchscreen and other Nest products. Pricing is still being determined. yalelocks.com
