Lockin YEEUU K421 is a smart safe with a code entry function, designed for safe storage of keys or small items. With an IP65 rating, the device is protected from rain and other outdoor conditions. It is operated via a mobile app available for Android and iOS. The safe supports different types of codes: temporary, cyclic, dynamic, offline, and masking (anti-peep), which allows you to hide the correct code among additional digits. The built-in Nordic 52832 chip ensures stable operation with low power consumption. The keypad with tactile springiness of the buttons guarantees precise code entry without accidental presses.

Multiple mounting methods and convenient use

The case of the K421 model allows for several ways of mounting - it is possible to fix it with expander screws, self-tapping screws, or suspend it with the included armband. The Tuya app allows you to open the safe with a smartphone via Bluetooth and access the opening history. In the event of a low battery, the user receives an audible and light signal, and with the use of a Wi-Fi bridge, it is also possible to receive remote status notifications.

Reliable power supply and long-lasting operation

The K421 safe can be powered in two ways - with 3 AAA batteries (up to 18 months of operation) or 2 CR123A batteries (up to 24 months). For those who use the device up to 10 times a day, such battery life means less frequent need to change the power source, which affects the convenience of use. App-based operation offers full access management, including the ability to grant permissions to others. Thanks to the NFC function (supported on Android), access can also be obtained by contactless without having to enter a code.
