Frequently Asked Questions
Q: Does the YRHAND H03 smart door lock work without a smartphone?
A: Yes! Even without a smartphone nearby, you can unlock the door using the built-in fingerprint reader, numeric keypad passcode, RFID card, or a physical mechanical key — so you're never locked out.
Q: Can I control the YRHAND H03 lock remotely from outside my home?
A: Remote control requires the optional G2 Wi-Fi Gateway (sold separately). Once connected, the TTLock app lets you lock, unlock, share eKeys, and view access logs from anywhere with an internet connection.
Q: What door types and thicknesses is this smart lock compatible with?
A: The YRHAND H03 is designed for doors 35–55 mm thick and is compatible with wood, glass, steel, aluminum, brass, and stainless steel doors. It supports single latch, 50/50, 85, and 72 mortise types, making it suitable for most standard residential doors.
Q: How do I share access with guests or service personnel?
A: Through the TTLock app, you can generate temporary passcodes or eKeys and share them directly with visitors, housekeepers, or tenants. You can set specific time windows for access and revoke permissions instantly — all remotely.
Q: How long do the batteries last, and what happens when they run low?
A: The lock runs on 4 standard AA alkaline batteries. Battery life varies by usage, but the lock sends a low-battery alert via the TTLock app well before power is exhausted. In an emergency, a micro-USB emergency power port (or 9V battery contact on the exterior) allows temporary power to unlock the door.
