What it is and who it fits

The FITNATE HS0335B is a black metal smart deadbolt designed for doors 32 to 48 mm thick. It unlocks by fingerprint, backlit touch keypad or physical key, and pairs with the YE-LOCKK app over Bluetooth for remote control. The chromium-coated finish resists wear and corrosion, while an auto-lock function secures the door within three seconds of closing. It suits homeowners or landlords wanting keyless entry on standard interior or exterior doors.

Who it suits and who should look elsewhere

This lock fits wooden, metal, glass and stainless-steel doors within the stated thickness range and installs with basic tools following the supplied manual. It is not suited for doors thinner than 32 mm or thicker than 48 mm, nor for frames that cannot accommodate a deadbolt mechanism. Buyers needing Wi-Fi connectivity without a separate gateway, or integration with a specific smart-home hub not supported by the YE-LOCKK app, should consider other options.

Behaviour under daily use

The fingerprint reader and backlit keypad remain responsive after repeated daily unlocking, and the metal chassis with chromium coating maintains its anti-skid surface through constant handling. Waterproof seals protect the electronics from rain and humidity on exterior doors. Battery life will vary with traffic, but the mechanical key override guarantees entry if power is depleted. The auto-lock timer consistently engages three seconds after the door shuts.
