The best smart door knob lock depends on how you want to unlock the door: fingerprint, keypad, app, or mechanical key. The KLLOQUE models suit buyers who want fingerprint access and selectable modes; Yamiry adds keypad entry; KUCACCI offers several access methods for an exterior-door setup; and iulock focuses on keypad codes and backup keys. Check door fit and whether remote access requires a separately purchased gateway before choosing.

KLLOQUE Matte Black Fingerprint Door Knob
This KLLOQUE smart knob is best for buyers who want fingerprint entry, app features, and more than one operating mode. It also supports mechanical-key entry, giving users an alternative way to unlock the door.
The listed modes are Passage, Normal, Privacy, and Silent. Normal Mode is described as having a five-second auto-lock. Through the app, users can set fingerprints, check access records, and share or add access. App control works within Bluetooth range; remote control requires a separately purchased gateway.
Limitation: The manufacturer says this lock is not suitable for doors with weather strips installed. Check the door before buying.
Yamiry Keypad Smart Door Knob
Choose the Yamiry if keypad access and Bluetooth app management are priorities. Its listed unlocking methods include passwords, fingerprints, and key fobs. The lock can store up to 50 passwords, fingerprints, and key fobs, according to the product information.
The manufacturer describes the body as aluminum and says installation can be completed with a screwdriver. It also states that the lock is compatible with most American standard doors. A separately sold Wi-Fi gateway is required for remote control; without it, the stated connection is Bluetooth.
Limitation: Buyers who need remote access should account for the separate gateway and confirm door measurements and fit before installation.
KLLOQUE Silver Fingerprint Door Knob
This silver-finish KLLOQUE model is best for buyers seeking the same core fingerprint and app functions as the matte black version in a different finish. Mechanical keys provide an additional entry method.
Its listed modes include Passage, Normal, Privacy, and Silent. Normal Mode has a seven-second auto-lock, compared with five seconds on the matte black model. The app supports fingerprint setup, access-record checking, and sharing or adding access. Bluetooth range is required for app control, while remote control needs a separately purchased gateway.
Limitation: The product is not suitable for doors with weather strips, according to its listing. Consider that restriction when checking your door.
KUCACCI Keypad Smart Lock With Handle
KUCACCI is best for buyers who want several access options in a handle-style smart lock. Its listed methods include fingerprint, PIN code, smartphone app, key fob, and mechanical key. The reversible handle is described as fitting left- or right-opening doors.
The product listing describes DIY installation with a screwdriver and no additional drilling or specialized tools. App features include assigning permissions, creating one-time or permanent codes remotely, and tracking access. Remote unlocking and Alexa voice control require a Wi-Fi gateway.
Limitation: The gateway is not included in the stated requirements for remote features. Confirm the lock’s installation fit and access needs before selecting it as an exterior-door replacement.
iulock Keypad Door Lock With Key Backup
The iulock is best for households that want individual keypad codes without relying on fingerprint or app access. It supports up to 50 customizable codes, each described as one to 15 digits, and includes two mechanical keys.
Its listed features include backlit keypad numbers, Passage Mode, Silent Mode, and a low-battery alarm. The product states that four AAA batteries can last up to 18 months and that a Type-C USB backup can be used if batteries run out. It is described for residential and commercial interior and exterior doors.
Limitation: The listed access options center on codes and keys, so choose another model if fingerprint or app control is essential.
Buying Guide: How To Choose A Smart Door Knob Lock
Which access method fits your household?
Fingerprint locks can reduce the need to enter a code, while keypad models let users unlock with a PIN. Some products combine these methods with keys, key fobs, or app access. Choose based on who needs entry and which methods each person can use reliably. A mechanical key can provide an alternate entry method when electronic access is unavailable.
Do you need remote control or local app access?
Bluetooth app functions are generally limited to nearby access, as stated for the KLLOQUE model. Remote control is a separate feature that may require a Wi-Fi gateway. Check whether the gateway is sold separately and whether the specific functions you want—such as remote unlocking or code sharing—depend on it.
Will the lock fit your door?
Check the product’s door requirements and installation details before ordering. The KLLOQUE models specifically exclude doors with weather strips. Yamiry says it fits most American standard doors, while KUCACCI lists a reversible handle for left- and right-opening doors. These statements do not replace checking your door dimensions and configuration.
What features matter for daily use?
Compare auto-lock timing, Passage or Privacy modes, keypad visibility, and backup entry. For example, the two KLLOQUE finishes list different Normal Mode auto-lock intervals: five seconds for matte black and seven seconds for silver. The iulock listing highlights backlit numbers, a low-battery alarm, and USB backup. Match these details to your routine rather than choosing by finish alone.
