• IC Card: 13.56 MHz MIFARE card that cannot be duplicated — easy to use for children and seniors.
• Mechanical Key: Backup key access ensures you're never locked out.
• Bluetooth / TTlock App: Connect directly via Bluetooth and manage access from your smartphone.

Smart Home Ready

The TTlock app (iOS & Android) lets you grant temporary e-keys, review access logs, set time-limited access, and connect to an optional Gateway for remote control via Alexa. Whether you're managing a rental or monitoring your front door from afar, this lock keeps you in control.

Emergency Power Backup

If the batteries run low, simply charge the lock via Micro USB (power bank compatible) to regain access through fingerprint, password, or card. A mechanical key override is also included for full peace of mind.

Free-Handle Design

The handle remains free until a valid credential is read. Once authenticated, simply push the handle down to open. Lift the handle up when closing to engage the deadbolt automatically — no extra steps needed.

Frequently Asked Questions

Q: What door types is the JCSMARTS TTlock smart lock compatible with?

A: The JCSMARTS JCF366TT is designed for slim doors including slim aluminum doors, sliding doors, framed glass doors, and standard wooden doors with a thickness of 30–65 mm. If your door is thicker than 70 mm, contact us to request longer screws at no extra charge.

Q: How does the anti-peep password feature work on this keypad door lock?

A: The anti-peep feature lets you enter random digits before or after your actual password code. As long as your real code is included in the sequence, the lock will recognize it — making it nearly impossible for onlookers to identify your true combination.

Q: Does this Bluetooth smart lock work without a phone or internet connection?

A: Yes. You can unlock the door using a registered fingerprint, password, IC card, or mechanical key entirely offline. The TTlock app and Bluetooth connectivity are optional features that add convenience and remote management; they are not required for everyday access.

Q: What happens if the batteries die on the TTlock smart lock?

A: If the batteries are depleted, you can charge the lock temporarily using a power bank via the Micro USB port, which restores fingerprint, password, and card access. Alternatively, the included mechanical key provides a reliable backup entry method. Replace the batteries as soon as possible after using emergency charging.

Q: Is a gateway required for Alexa voice control?

A: The lock supports a separate TTlock Gateway accessory (sold separately), which enables remote access and Alexa voice control over Wi-Fi. Without the gateway, the lock operates locally via Bluetooth within standard smartphone range.
