Biometric Door Knob Lock for Interior Keyless Entry
This five-in-one biometric door knob lock offers fingerprint recognition, smartphone app control, IC card access, password entry, and mechanical key access. Designed for compatible bedroom, apartment, and interior doors, it combines several entry methods with silent and passage modes.
For late-night bedroom entry, silent mode lets you mute operating sounds. When a room needs frequent access, passage mode keeps the door unlocked rather than requiring repeated authentication. Choose the available configuration that matches your needs and confirm its package contents before ordering.
Key Features
- Five entry methods: Choose fingerprint, app, IC card, password, or mechanical key access.
- Silent and passage modes: Mute operating sounds or keep the door unlocked when access restrictions are not needed.
- Anti-peep keypad: Supports extra digits around the correct PIN. This feature does not guarantee that a PIN cannot be observed.
- Voice reminders: Audio prompts guide operation.
- Low-battery alerts: Lists a red keypad indication and voice alert when battery power runs low.
- Type-C emergency power: Provides temporary external power support, not battery charging.

Frequently Asked Questions
Which ways can I unlock the door?
The listed methods are fingerprint, smartphone app, IC card, password, and mechanical key access.
What does passage mode do?
Passage mode keeps the door unlocked for repeated entry. Use it only when you do not need to restrict access.
Can I charge the batteries through Type-C?
No. The listed Type-C port supplies emergency power and is described as non-recharging. Follow the product instructions for normal battery replacement.
How do the two options differ?
The option labels are Ball lock 5-in-1 and 5-in-1-2pc spherical lock. Both list five-in-one access. Confirm the exact lock, key, and IC card quantities for the selected option rather than assuming the same package contents.
Will it fit my existing door?
Exact door thickness, bore diameter, and backset requirements are not provided. Confirm those measurements and the mounting requirements before ordering.
