Frequently Asked Questions

Q: Does the JCSMARTS TTlock smart door lock require Wi-Fi to work?

A: No — the lock communicates directly with your smartphone via Bluetooth, so no Wi-Fi is required for day-to-day use. If you want unlimited-range remote access and voice-assistant integration, you can add the optional G2 Gateway, which bridges the lock to your home Wi-Fi network.

Q: How many passwords, cards, and users can the TTlock app manage?

A: The TTlock app lets you add and delete an extensive list of credentials, including RFID cards, PIN codes, and eKeys (shareable digital keys). You can grant temporary or recurring access to family members, housekeepers, or guests and revoke it at any time — all from the app.

Q: What happens if the batteries run out?

A: The lock gives a low-voltage warning alert before the batteries are fully depleted, so you have plenty of time to replace them. In an emergency, the two included mechanical backup keys always provide physical access regardless of battery level.

Q: Is this smart door lock compatible with doors other than wooden doors?

A: The JCDB210 is optimised for wooden doors with a thickness of 38–60 mm and is also compatible with steel doors. It replaces a standard knob lock with no additional drilling required. Always check your existing mortise dimensions against the provided mortise-size diagram before purchasing.

Q: Can I check who entered and when using the TTlock app?

A: Yes. The TTlock app logs every door-opening event along with the method used (app, keypad, card, etc.) and timestamp. With the optional G2 Gateway connected, records are uploaded in real time so you can monitor access from anywhere.
