Smart lock fit
Compare retrofit locks, replacement deadbolts, and handle-style options before changing hardware, keyways, or keypad access on an existing door.
Stop juggling keys and wondering who's at the door. The GHome Smart 3 in 1 Door Lock turns your front door into a command center. Use your fingerprint, a code, your phone, or the physical key to get in. Unlock takes just 0.3 seconds—fast enough for when your arms are full of groceries.
The built-in 2K HD camera and doorbell let you see and talk to visitors from anywhere. The 172-degree wide-angle view shows the full porch, no more blind spots. You'll get an alert when someone approaches, and the two-way audio lets you tell the dog walker to leave a package or ask the delivery driver to set it behind the planter.
Setup takes minutes with just a screwdriver—no drilling or wiring needed. The 10000mAh battery lasts through months of use and recharges via USB-C. Works with standard US deadbolt holes. You can manage up to 50 fingerprints and 100 passcodes, perfect for a family or rental property. Monitor activity, grant temporary codes, and check the video log from the app. This lock gives you control and keeps your home secure.
