- [Keep Kids & Guests Out of What Matters Most] Take control of your personal space at home. This fingerprint door knob lock helps keep curious kids away from snacks, medications, or personal belongings, while preventing roommates or guests from entering your bedroom, closet, or home office without permission. Enjoy simple, reliable privacy, no complicated door locks to manage.
- [Fast & Easy Fingerprint Unlock, Keyless Convenience] Unlock your door in just 0.3 seconds with a highly responsive biometric fingerprint (thumbprint) sensor — no keys, no waiting. Even with your hands full, simply tap and go. This keyless entry door lock stores up to 20 fingerprints, making access easy for the whole family. Perfect for busy households that need fast, hassle-free entry every day.
- [Never Get Locked Out, 3 Ways to Unlock] Never worry about being locked out again. This smart door knob for bedroom gives you 3 easy ways to unlock — fingerprint, app, or backup key. Even with low battery, the mechanical key ensures you always have access. A built-in 400mAh rechargeable battery with alerts and Type-C charging keeps this bedroom door lock ready every day.

- [Easy Installation, No Drilling or Wiring Needed] Install this interior door lock in about 20 minutes with just a screwdriver — no wiring or door damage required. Fits most US standard doors 1-3/8" to 2" (35–50mm) thick with a standard 2-1/8" (54mm) bore hole and adjustable 2-3/8" or 2-3/4" (60/70mm) backset for a secure, stable fit. Designed to replace most standard door knobs — we recommend checking your door dimensions for the best fit. Not compatible with doors with weather stripping.
