Frequently Asked Questions
Q: Does the YRHAND smart door lock require an external WiFi gateway?
A: No — the YRHAND 3S02 has a built-in WiFi gateway, so it connects directly to your home WiFi network. You do not need to purchase or install any additional hub or bridge to use full remote control features via the TT Lock APP.
Q: How does the 3D face scanning unlock work, and is it secure?
A: The 3D face scanning uses depth-sensing technology to map your facial structure in three dimensions, enabling contactless entry in seconds. Because it analyzes a true 3D model — not just a flat image — it is designed to resist photo and video spoofing, making it significantly more secure than standard 2D face-recognition systems.
Q: What happens if the battery runs out?
A: The lock includes two backup options: you can use the emergency USB port to supply temporary external power to operate the lock, or use the included mechanical backup key for direct physical entry. The TT Lock APP also sends a low battery alert so you have plenty of notice to recharge.
Q: Can I grant temporary access to guests or service providers?
A: Yes. Through the TT Lock APP you can create multiple password types including one-time passwords, time-limited passwords, and recurring passwords — ideal for guests, housekeepers, or delivery windows. Access automatically expires after the set period without any manual action needed.
Q: Is this smart lock compatible with my door?
A: The YRHAND 3S02 is designed to fit most standard residential doors with a thickness of 35–90 mm. It supports wooden, steel, brass, and stainless steel doors, and the handle direction is reversible to accommodate both left- and right-handed door configurations.
