The Yamiry H1B Smart Door Lock provides a comprehensive keyless access upgrade for modern homeowners, Airbnb hosts, and rental property managers seeking to eliminate traditional physical keys.

Designed as a complete electronic lever handle replacement, this versatile unit swaps out standard interior or exterior door handle sets to streamline daily entry and guest access management.

Operating as a 6-in-1 access system, it pairs a fast biometric fingerprint scanner integrated directly into the handle with an anti-peep touchscreen keypad, contactless IC card fobs, smartphone app controls via the TTLock ecosystem, voice commands (when paired with a gateway), and traditional physical backup keys.

Reasons to buy

Versatile 6-in-1 unlocking options: Combines high-speed biometric fingerprint scanning, anti-peep keypad PINs, IC card fobs, smartphone app controls, and physical keys.
Ideal for rental hosts and offices: TTLock app integration enables property managers to issue temporary, recurring, or duration-based passcodes remotely.
Generous storage capacities: Holds up to 200 unique fingerprints, 200 passcodes, and 200 IC card profiles, ideal for busy households or shared spaces.
Anti-Peep security safeguards: Allows users to input random numbers before or after their actual PIN code to prevent onlookers from stealing passcodes.
Reversible handle alignment: Easily adjusts to fit both left-handed and right-handed door swings without requiring extra modifications.

Reasons to avoid

Requires separate gateway for remote Wi-Fi control: Uses local Bluetooth connectivity out of the box, meaning out-of-home remote monitoring demands a separate Yamiry Wi-Fi bridge.
Batteries not included: Requires purchasing four standard AA alkaline batteries separately prior to installation.
Uses Micro-USB instead of USB-C: The emergency external power port utilizes an older Micro-USB interface rather than modern USB-C cables.
