Frequently Asked Questions

Q: Does the SN-9243 smart lock module work without the Gateway G2?

A: Yes — the SN-9243 works fully as a Bluetooth smart lock module using only the TTLock app on your smartphone via BLE 5.0. The Gateway G2 is only required if you want remote Wi-Fi access (from outside Bluetooth range) or wish to use Amazon Alexa and Google Home voice control.

Q: Can I share digital keys with multiple people, like tenants or family members?

A: Absolutely. The TTLock app lets you send time-limited digital keys to as many users as you need. You can set precise start and end dates for each key, freeze or revoke access instantly, and view a log of every access event — making it perfect for rental properties, vacation homes, and shared offices.

Q: Is the SN-9243 compatible with my existing electric door lock?

A: The SN-9243 is designed to retrofit most standard electric door locks that operate on 4.5V–10V DC. It's recommended to verify your existing lock's voltage and wiring before installation. If you're unsure, consult an electrician or refer to your lock's manufacturer documentation.

Q: How do I download the TTLock app and set up the module?

A: Download the free TTLock app from the Apple App Store or Google Play Store, or scan the QR code included in the product documentation. Once installed, follow the in-app pairing instructions to connect the SN-9243 module via Bluetooth and add yourself as the administrator.
