✴︎ Unopened, shrink-wrapped Lock Ultra ✴︎ Facial recognition pad set. ※ Shipping is unavailable from December 30th to January 4th. Purchase date: Late November 2025 Lock Ultra is unopened and shrink-wrapped. The facial recognition pad has been activated once, so the battery insulator has been removed, and the contents and outer box have been opened. Although it is unused, please refrain from purchasing if you are concerned about storage. Returns are not accepted. 【Your face is the key to the door】 Adopting the latest 3D facial recognition system, smooth facial recognition is possible regardless of makeup or whether you are wearing glasses. It is designed to be easily recognized even in dark places or places with little lighting. Convenient when your hands are full with luggage, or when your fingers are wet with rainwater or sweat. In addition to fingerprint authentication and passcode input, it also supports unlocking using transportation IC cards such as Suica and NFC cards. 【Can be used for about 1 year on a single charge】 Lock Ultra uses a 4200mAh rechargeable battery, and the facial recognition pad uses a 5000mAh large-capacity rechargeable battery. The battery life is about 1 year, and it is convenient because there is no need to replace batteries compared to CR123A AA lithium batteries. The Lock Ultra has a triple power supply system. Even if the main battery runs out of charge, it is equipped with CR123A lithium batteries as a spare battery so that you can open the door as usual, and the microcurrent unlocking function in case of emergency eliminates the risk of being locked out due to battery depletion. 【Unlocking is faster and quieter】 With a full upgrade of the motor, the unlocking speed is 78.6% faster, and the motor's rotational power is 50% higher (compared to Lock Pro). With the devices always connected, you can smoothly unlock the door the moment you stand in front of it, without waiting for connection or response. In addition, it is equipped with Japan's first (as of 2024, according to our research) silent mode. The operating noise is less than 20dB, and it automatically locks at the specified time every night, switching the motor sound to silent mode.
