The Yale Assure Lock 2 Touchscreen Keypad Deadbolt with Wi-Fi, Keyless offers 2 key-free options to access your door: 4-8 digit passcode entered into the touchscreen keypad and virtual keys or on-demand remote access through the Yale Access app. Up to 250 codes can be created and shared with guests, family members, and renters. You can check on the lock's real time status, receive notifications when the lock is used, and decide who can unlock your door and when through the Yale Access app. Additional features include two-step verification, auto-locking the door, battery backup, voice control, and smart home integration with select popular home automation hubs. The Assure Lock 2 includes a Yale DoorSense Sensor which tracks the precise location and status of your door to inform you of your door and lock's status. The DoorSense Sensor works with the Yale Access app on your mobile device to assist Auto-Lock and Auto-Unlock features by ensuring that the door is in the correct position before the lock re-engages or unlocks itself. When your mobile device enters Bluetooth proximity range of the Assure Lock 2, the lock will automatically unlock for easy entry and automatically lock itself once your mobile device leaves Bluetooth range or after a set period of time. Through the Yale Access app, this Yale Smart Lock is designed to work with Autoslide's AutoSwing Automatic Door Operator. The AutoSwing can automatically open the door when the Yale lock is unlocked to enable hands free operation of your front door. You can control both devices from either the Yale Access app or Autoslide app from anywhere, plus share access with others, and check on device status and usage history.
