Tired of fumbling for keys? Upgrade to keyless convenience with the EUERTE Smart Door Knob! This is a great, straightforward option for bedrooms, home offices, garages, or rental properties. It replaces your existing interior doorknob and has a built-in electronic keypad on the outside. You can program up to 3 master codes and 17 regular user codes (4-8 digits long), so you can give temporary access to cleaners, guests, or kids without handing out physical keys. It also comes with 2 physical backup keys just in case. It features a handy auto-lock function that locks the door automatically 5 seconds after it closes – perfect for peace of mind. You don't need a smartphone or Wi-Fi app; it all works right on the keypad. It has different modes (privacy, passage, normal) controlled by a button inside. Installation is pretty standard and fits most US doors with a 2-3/8\ or 2-3/4\ backset. The battery is rechargeable and lasts about 10 months. A simple, effective way to add modern security and convenience to any interior door.
