This keyless entry keypad door knob lock offers a practical upgrade for residential doors, combining electronic convenience with a polished brass finish that complements traditional and modern interiors. The lock body is constructed from durable zinc alloy and brass, providing resistance against corrosion and daily wear. Its surface is smooth to the touch and designed to maintain its appearance over time. The keypad features responsive tactile buttons with backlighting for easy operation in low light.

The lock operates on four AA batteries (not included) and includes a low-battery indicator to prevent unexpected lockouts. Users can program a custom PIN code between 4 and 10 digits, with support for up to 20 user codes, making it suitable for families or small shared spaces. The auto-lock function allows the door to secure itself automatically after a preset delay, while the one-touch locking feature enables immediate locking from the inside by simply pressing a button.

Installation is straightforward with a standard door preparation, and the included mounting hardware fits most residential door thicknesses. The internal mechanism is designed for quiet operation and reliable engagement. This lock is suitable for front doors, bedrooms, offices, and interior passages where keyless access is desired.

It offers an affordable solution without compromising on essential security functions. The polished brass variant adds a warm metallic tone that coordinates well with existing door hardware. While not intended for high-security commercial applications, it provides adequate protection for everyday home use.

The product undergoes quality control checks to ensure consistent performance. Its battery life typically lasts several months under normal usage, and the backup mechanical key override offers a fallback option. This smart digital lock balances functionality, ease of use, and cost-effectiveness for budget-conscious homeowners seeking a keyless upgrade.
