4. Troubleshooting
For detailed troubleshooting steps and common issues, please refer to the official Troubleshooting Guide PDF available online. Some common issues and considerations include:
- Key Compatibility: The lock uses an SC1 5-pin key type. If re-keying, ensure the replacement pins match the specific dimensions of the Aqara U100 cylinder, as standard Schlage pins may not fit due to slight size differences.
- Installation Issues: Ensure the deadbolt is fully retracted and the latch hole is level during installation to prevent jamming.
- Connectivity: A Zigbee 3.0 hub is required for full smart home integration and remote access. Without it, functionality may be limited to Bluetooth via the Aqara app.
