## Long description

The Atlo ATLO-KRM-821-TUYA mechanical combination door lock is a replacement or upgrade option for residential and light commercial doors. It provides mechanical keypad entry with the option to use a physical key, combining traditional keyed access with a code-operated mechanism. The product is described as compatible with the Tuya ecosystem, enabling integration into broader smart-home setups that support Tuya-enabled devices.
Advantages
This mechanical combination lock offers dual access methods—code entry and keyed override—without relying solely on electronic power, which keeps operation reliable during power interruptions. Its compatibility with the Tuya ecosystem allows pairing with Tuya-capable systems for remote monitoring and automation when connected through supported interfaces. The lock is suitable for straightforward installation into standard door preparations and is intended to replace common mechanical locks while preserving conventional door operation.
Suitable for
 Residential exterior and interior doors where mechanical code entry is desired
 Small offices and commercial premises requiring keyed and code access
 Door lock replacement or upgrade projects for standard doors
 Integration with Tuya-based smart-home systems (when used with compatible converters or modules)
Key specifications
 Access methods: mechanical keypad code input and keyed override
 Compatibility: designed for integration with Tuya-compatible smart-home ecosystems
 Intended fit: standard single-door installations for residential and small commercial use
 Operation: mechanical code mechanism, no dependence on continuous electrical power for primary locking function
 Construction: metal lock body and keypad components suitable for door-mounted installation
How to use
Install the lock in place of an existing mechanical door lock following the manufacturer's mechanical fitting requirements and aligning the latch and strike plate to the door frame. Set a personal code according to the included setup procedure and verify correct operation of both the code mechanism and keyed override. Use the keypad to lock and unlock by entering the assigned code; use the physical key for emergency access or when alternate access is preferred. When integrating with Tuya systems, follow the integration instructions for the specific Tuya interface or adapter used to enable remote control and status reporting.
Usage recommendations
Choose a unique, non-obvious code and change it periodically. Verify compatibility and any additional hardware or gateway required to connect the lock to a Tuya ecosystem before installation. Ensure the lock is installed by a qualified person if not experienced with door hardware to maintain proper alignment and secure operation.
