The FEOCEY smart lock installs entirely on the inside of your door with a simple screwdriver. It fits most standard US doors and single-cylinder deadbolts (2-3/8″ or 2-3/4″ backset). Enjoy keyless entry while keeping your original keys as a backup. Perfect for renters, homeowners, Airbnb hosts, and landlords looking for an easy, hassle-free smart lock solution.

Our advanced coreless motor and power-saving tech deliver up to 10 months of reliable use (based on 10 cycles/day, actual usage may vary). Plus, get proactive app alerts when battery drops to 20%—so you can replace batteries timely and avoid unexpected lockouts—no panic, no last-minute runs.
【Precision Gyroscope Auto-Lock & Door Ajar Alerts – End the “Did I Lock It?” Anxiety】 Stop wondering “Did I lock the door?” A built-in gyroscope (no extra door sensors) detects door position: auto-locks when closed, sends real-time phone alerts if ajar (Wi-Fi required).
