Key specs for this smart knob
Access Methods: Fingerprint, mechanical key
You unlock the door using your unique fingerprint or a physical key. The system stores up to 100 fingerprints for family members. This dual approach ensures access even if the battery dies or the sensor fails. You should compare this to locks that require batteries only, as the mechanical key provides a reliable backup for emergencies or guests without registered prints.
Fingerprint Capacity: 100
The lock can store 100 different fingerprints. This capacity supports large households or shared living spaces with many residents. You can register multiple family members without needing to delete old entries immediately. When shopping, consider whether you need more than 100 users. This limit is sufficient for most apartments and homes but may require management for larger groups.
Auto-Lock Delay: Within 5 seconds
The door automatically locks itself within five seconds after you close it. This feature ensures the door is never accidentally left unlocked. You gain peace of mind without needing to twist the knob manually. This is faster than manual locking, reducing the risk of forgetting. Compare this to locks with longer delays or no auto-lock, which require more user attention to maintain security.
Rechargeable Battery: 600mAh
The device uses a 600mAh rechargeable battery that lasts up to six months. You charge it via a Type-C port, similar to a smartphone. A low-battery alarm warns you before power runs out. This eliminates the need for frequent battery replacements. When comparing, note that this rechargeable option offers convenience over disposable batteries, though you must remember to plug it in periodically.

Setup and everyday use guide
Installation requires only a small screwdriver and takes about ten minutes. The unit fits most standard US doors with thicknesses between one and three-eighths inches and two inches. You do not need professional tools or complicated wiring to mount it. This simplicity makes it suitable for renters who need a reversible solution without modifying the door frame.

Who Should Buy This Smart Knob
You should consider this Hiencetec knob if you need simple, keyless access for a bedroom or private office.

Keep the two emergency keys in a safe place, not on the door itself. This device fits doors between one and three-eighths inches and two inches thick. Verify your door’s thickness before ordering, as it will not fit non-standard sizes. The auto-lock engages within five seconds, which is useful if you frequently forget to turn the latch. It operates independently, so it does not connect to your Wi-Fi or smartphone. You will not get remote locking features found in smart locks. If you want app control, look elsewhere. For basic biometric entry, this unit works well. It pairs nicely with video doorbells at your front entrance, offering a complete entry solution without complex wiring.
Check before you buy
- Check door thickness is between 1.375 and 2 inches.
