Installation Notes
This lock is designed for indoor wooden doors up to 60 mm thick. The concealed design means the locking mechanism is hidden entirely within the door frame — no exterior marks or visible hardware. The magnetic closing principle ensures the bolt is only engaged when the tongue and buckle are perfectly aligned, providing reliable, consistent locking every time.

Frequently Asked Questions
Q: Does the TTLock Smart Invisible Bolt Lock work without Wi-Fi?
A: Yes! The lock uses Bluetooth to communicate directly with your smartphone via the TTLock app, so Wi-Fi is not required for basic unlocking. However, to enable remote access and voice control through Alexa or Google Assistant, you will need the optional TTLock G2 Gateway connected to your home Wi-Fi network.
Q: Is this smart bolt lock suitable for metal or glass doors?
A: No — this lock is designed specifically for indoor wooden doors up to 60 mm thick. It is not compatible with metal, glass, or exterior doors, and is not waterproof, so outdoor installation is not recommended.
Q: How long do the batteries last, and what happens when they run low?
A: The lock runs on 4 × AA dry batteries (not included) with an estimated battery life of approximately one year under normal use. When the battery runs low, the lock will trigger a low battery audio alert and automatically release the latch, ensuring you're never locked out during a battery replacement.
Q: Can I share access with family members or guests using the TTLock app?
A: Absolutely. The TTLock app allows the administrator to issue and manage IC card access as well as app-based eKeys for family members, guests, or temporary visitors. All unlock activity — whether via card or app — is logged and visible to the administrator once the app syncs with the network.
