Smart Keypad Door Knob, Bright Black

For households that want keypad entry on an interior door, this smart door knob offers a choice of password access or a mechanical key, plus settings for passage, privacy, and quieter operation. It may also suit an apartment or office where people need to share access without relying on a key for every entry.

The controls are local: keypad access must be within the door’s range, and remote control requires an additional unit. That distinction matters if you expect to manage the lock from elsewhere.

Best use cases

This lock makes the most sense for a bedroom, home office, or other door where privacy and convenient entry matter more than remote access. Passage Mode keeps the door available without normal locking behavior, while Privacy Mode is aimed at times when you want the room less accessible. Normal Mode automatically locks after five seconds, and Silent Mode provides a quieter operating option.

Picture someone moving between rooms with their hands full: a shared password can avoid searching for a key, while the mechanical key gives you another way to enter if needed. Would you rather keep a door freely accessible at certain times, or have it lock automatically after use? The selectable modes help tailor that choice to the room.

Worth considering if household members need shared keypad access and you’re comfortable managing settings at the lock. Better avoided if you need remote unlocking as a built-in feature, or if the door has weatherstripping, the product is explicitly not suitable for doors with weather strips installed.

Product specs

The lock has keypad control, password setup and access management through a program, and a mechanical key for entry. The description says access can be shared or added for family members, but it does not specify the number of passwords supported. The keypad needs to be within the door’s range. Remote control is not included as described and requires another unit.

Power comes from a rechargeable battery with a stated one-year battery life. It charges through USB Type-C, and a low-battery notification can be enabled. When the battery falls below 20%, the lock signals this with a light during unlocking. Battery life will still depend on real-world use, so the stated duration is best treated as a guide rather than a guarantee.

Installation uses a screwdriver. The instructions emphasize aligning both knobs with the “UP” marks and placing the spindle bar vertically, incorrect orientation may keep the interior knob from fitting into place. On the spec sheet, the range of modes and backup key make this more flexible than a basic keyed knob, but it is not a complete remote-access setup on its own.

Where it shines

Its strongest appeal is combining several everyday entry options in one knob. A bedroom can be left in Passage Mode when people are moving in and out, then switched to a locking mode when privacy matters. The physical key also gives you a non-keypad entry method, while the low-battery light provides a visible warning rather than leaving battery status entirely to guesswork.

The trade-off is that keypad access is not the same as remote access. If you want to unlock a door while away from it, the listed setup requires an additional unit. And while installation is described as straightforward, the alignment directions are specific enough that careful fitting matters.

Final verdict

Choose this bright black keypad door knob if you want password entry, a mechanical-key backup, and selectable modes for an interior door, and its local-control setup matches how you’ll use it. Skip it for a weatherstripped door or if remote operation is essential without buying another unit. That makes it a practical fit for access and privacy at the door itself, rather than a standalone solution for controlling entry from a distance.
