5. **Basic Security for High-Risk Areas** While secure for most homes, this lock may not meet the standards for high-security needs (e.g., commercial properties or areas with frequent break-ins).

6. **No Auto-Relocking** Unlike some smart locks, this deadbolt does not automatically relock after use, requiring manual engagement.
