This keyless entry knob lock integrates a backlit keypad and a traditional key override, offering flexible access control for bedroom, exterior, and interior doors. The lock body is constructed from zinc alloy with a weather-resistant coating, providing durability against outdoor elements while maintaining a sleek black finish.

Internally, the mechanism uses a motorized latch that operates with four AAA batteries, delivering reliable auto-lock and unlock functions. The keypad features raised tactile buttons and an anti-peep code entry system, which allows users to input random digits before the actual code to prevent onlookers from learning the combination. The lock supports up to 20 user codes, making it suitable for households or small offices where multiple individuals need access. The auto-lock function can be programmed to engage after a set time delay, ranging from 10 seconds to 99 seconds, ensuring doors are secured automatically. Installation requires only a screwdriver and takes approximately ten minutes. The lock fits standard door prep for knob locksets, with adjustable latch backsets to accommodate 2-3/8 or 2-3/4 inch doors. The exterior keypad module is IP54-rated, offering protection against rain and splashes for outdoor use. From a performance standpoint, the lock uses a low-power motor and smart battery management that provides up to one year of typical use under standard conditions. A low-battery indicator on the keypad gives advance warning. The key override uses a standard five-pin key cylinder, which serves as a reliable backup during power outages or if the batteries run out. The interior turn knob allows quick manual locking from inside without needing the code. This lock is designed for users who want a cost-effective upgrade from traditional keyed knobs without sacrificing security. It works well in rental properties, vacation homes, garages, or any entry point where keyless convenience is valued. The combination of waterproof construction, easy programming, and a reasonable price point makes it a practical choice for both interior and exterior doors. All materials are lead-free and comply with standard safety regulations. The tactile feedback of the keypad and smooth rotation of the interior knob contribute to a pleasant user experience.
