The Keypad Access Smart WiFi Lock allows you to create and manage up to 50 access codes for trusted friends and family for recurring, one time temporary, timing temporary, or permanent access to your home or office. You can remotely grant accesses with the mobile app and set a single or combination codes unlock mode. It fits most pre-drilled 2-3/8" or 2-3/4" backset knob or cylindrical lock doors, which often can be found from your local door window store. The lock is weatherproof and suitable for interior and exterior doors. It only takes a screwdriver (included) and minutes to install and set up it. Neither wiring nor drilling is required.
Auto-lock will mechanically lock itself when the door is closed. From outside, you can turn the handle but the door will be locked. The only way to unlock the door from the outside is by key or code(s). From inside, simply turn the handle and unlock the door. It works like a regular lock, no key or code needed.
