Frequently Asked Questions
Q: What app does the YRHAND 350BL smart door lock use?
A: The YRHAND 350BL uses the TTlock app, available for free on both iOS and Android. Through the app you can lock/unlock the door remotely via Bluetooth, issue virtual e-keys to guests with time-limited access, set automatic lock schedules, and review entry history logs.
Q: Does this electronic door lock work on any door type?
A: The 350BL is designed for wooden doors with a thickness of 38–50 mm. If your door exceeds 50 mm, please contact us before ordering so we can advise on compatibility or provide an extended spindle.
Q: How is the YRHAND smart lock powered, and how long do the batteries last?
A: The lock is powered by 4 × AA batteries (not included). Battery life varies with usage frequency, but most users report several months of normal use. The TTlock app will notify you when battery level is low so you can replace them before they run out.
Q: Can I share access with multiple people?
A: Yes. Via the TTlock app you can create and send virtual e-keys to family members, housekeepers, or guests — each with customizable time restrictions (one-time, recurring, or always-on). You can revoke access at any time directly from the app.
Q: What happens if my phone battery dies or Bluetooth is unavailable?
A: No problem — the 350BL offers three additional entry methods: the keypad passcode, an M1 card, or the included mechanical backup key, so you're never locked out regardless of phone connectivity.
