Keypad Smart Door Knob Lock, Yamiry
The Yamiry keypad lock uses aluminum alloy for enhanced security and is designed for front doors. It offers a backlit 4–8 digit code, a weather-resistive IP54 rating, a low battery indicator, and an anti-prying user code feature. Best for homeowners who want quick, screw-driver installation in under 15 minutes and the option to upgrade access with a one-time guest code. Caution: If battery power is low, unlock via the mechanical key still works, but you may want to keep spare keys handy.
iulock Keypad & Key Smart Door Lock
This keypad knob offers up to 50 user codes and a hardy metal construction, including a backlit keypad for day or night use. It includes two mechanical keys and a USB Type-C backup option when batteries run low. Designed for homes, offices, rentals, and hotels, it’s a solid choice for properties requiring scalable access control. Choose this if you need many distinct codes and a modern look; consider the battery life in high-traffic situations as a potential limitation.
Evanshow Fingerprint Door Lock
The Evanshow lock combines biometric access with a keypad, two mechanical keys, and IC cards. It supports up to 100 fingerprints and 50 passwords, offering fast 0.5-second recognition. A USB port allows emergency power, though it does not power the internal batteries. Best for users who want a keyless option with quick fingerprint entry; note that administrator fingerprint setup is required before first use to prevent unauthorized access during setup.
Veise KS03 Keypad Door Knob Lock
The Veise KS03 locks provide up to 20 user codes plus a one-time code. It supports easy 10-minute installation and works with most American standard doors. Features include auto lock, passage mode, and an anti-peeping password option to protect against observation. Best for front doors and rentals where quick reprogramming and flexible access are important; limitation is the focus on standard door thickness and handedness compatibility.
NICE DIGI Keypad Door Lock
The NICE DIGI keypad lock provides secure, keyless entry with up to 20 personalized codes and a straightforward installation. It does not require an app or network connection, making it suitable for rentals or offices that prefer a simple, stand-alone system. Auto-lock and a flexible passcode setup help support everyday security. Best for users who want a no-fuss, code-based entry method; limitation is the lack of remote or app features.
