Keypad Lock ATLO-KRM-855-V2 Wi-Fi Smart Mortise Door Lock, Black

Unlike ordinary mechanical locks, the ATLO-KRM-855-V2 puts a full access control system into a compact mortise body. It connects directly to your 2.4 GHz Wi-Fi network, so you can manage entry from anywhere via the Tuya Smart or Smart Life app. No extra hub is required, and the built-in Bluetooth acts as a fallback for local configuration.

Highlights

• Wi-Fi (2.4 GHz) and Bluetooth connectivity for remote and local control
• Four access methods: PIN code, RFID card, mobile app, and mechanical key
• Supports up to 200 users (PINs and cards combined)
• Anti-peep code function – add random digits before or after the real PIN to hide it from onlookers
• Auto-lock feature for automatic relocking after entry
• Voice assistant support via Tuya: Amazon Alexa and Google Assistant
• Emergency USB-C power port for dead-battery situations
• Low battery warning in the app and on the keypad

In daily use

The keypad is backlit for night use and responds with clear feedback. Battery life reaches up to 10,000 openings or 6–12 months depending on usage, powered by four AA batteries. When the batteries run low, simply connect a USB-C power bank to the emergency port to operate the lock. The zinc alloy and ABS construction holds up in temperatures from -20°C to 60°C and humidity up to 90% RH (non-condensing).
