The Yamiry keypad smart door knob lock combines a compact electronic code entry system with an integrated handle, providing a practical upgrade for front doors without requiring extensive wiring or professional installation.

Constructed from a zinc alloy outer shell and reinforced ABS internal components, the lock offers resistance to everyday wear while maintaining a smooth, tactile finish. The keypad surface uses raised, wear-resistant buttons that respond to light pressure, ensuring reliable code entry over repeated use. A built-in microchip processes user input quickly, reducing lag between pressing a code and the latch disengaging. The lock operates on four AA batteries (not included), lasting up to several months under normal usage, with a low-battery warning indicator that flashes when replacement is needed. The programming interface allows users to set up to 20 unique access codes, making it suitable for households with multiple members or for granting temporary entry to guests and service personnel. The lock mechanism uses a standard deadbolt latch with a durable steel bolt, providing basic security for interior or exterior doors that are not primary high-security entry points. The handle is ergonomically designed for right-handed or left-handed use, with reversible installation that accommodates most standard door thicknesses. The electronic components are sealed to resist dust and moisture, though the lock is recommended for covered or sheltered installation to prolong lifespan. From a performance standpoint, the lock automatically locks itself after each entry, requiring a code or the manual thumb turn on the interior side to release. The keypad backlight illuminates briefly when any button is touched, aiding visibility in dim light. The lock does not include Wi-Fi or Bluetooth connectivity, focusing instead on straightforward code‑based access without the need for smartphone apps or network configuration. This simplicity contributes to a stable operation free from connectivity issues. The overall build quality reflects a balance between affordability and functional reliability, with attention given to fit and finish. The lock is compatible with standard 2-3/8 inch or 2-3/4 inch backset doors and uses a standard 1 inch bore hole, making retrofitting quick for most existing doors. For added convenience, a mechanical key override is included, allowing entry when batteries are depleted. The installation kit includes all necessary screws, mounting plates, and clear instructions, enabling a straightforward DIY setup in roughly fifteen minutes. The lock does not require any drilling for most standard doors, as it uses existing door prep holes. The price point at under seventy dollars places it as a very affordable option for those seeking a keyless entry solution without investing in a fully connected smart lock. The finish options include satin nickel and matte black, both resistant to minor scratches and fingerprints. This lock is well suited for rental properties, secondary doors, or anyone wanting to eliminate physical keys for straightforward access control. Its durability is adequate for moderate daily use, though heavy‑duty applications may demand a sturdier construction.

The Yamiry keypad lock offers a reliable, budget‑friendly introduction to keyless entry with essential features and dependable performance.
