Yes, smart locks represent a multi-dimensional upgrade in security philosophy.The security core of a traditional mechanical lock lies in the complexity of its cylinder (with Grade C being the best). A qualified smart lock, while inheriting an excellent mechanical cylinder (often Grade C), adds"active defense" and "real-time monitoring"capabilities. It not only resists physical prying but can also provide instant warnings and deter criminal attempts through features likeanti-prying alarms, multiple incorrect attempt alerts/lockouts, and remote notifications. Security is reflected in the combination of"difficult to break" + "know immediately if tampered with."

Absolutely not. This is a fundamental safeguard of smart locks.
All legitimate smart locks come with at least two emergency entry methods:

1. Emergency Physical Key: A hidden keyhole at the bottom or side of the lock body allows entry using a spare mechanical key (recommended to be stored at the office, in your car, or with a trusted friend/relative).
2. Emergency Power Interface: Most use mainstream USB-C ports or universal 9V battery contacts. Using a power bank or a 9V battery for temporary power can "revive" the lock for entry.
   Simultaneously, smart locks provide multiple early warnings when battery levels drop below 20%, through voice reminders and app notifications with each use, reminding you to replace the batteries promptly.

1. Door Type: 95% of inward/outward opening security doors, wooden doors, brass doors, and double doors can be fitted.
2. Door Swing Direction and Thickness: Simply select "Left/Right Handed" and "Inward/Outward Swing" when purchasing. Door thickness generally ranges from 3.5cm to 5cm, which is within the supported range.

Long battery life and easy replacement.

• Battery Type: Commonly uses 8 AA alkaline batteries.
• Battery Life: Under normal household use (10-15 openings/closings per day), it can last 10-15 months. For models with power-intensive features like facial recognition or a peephole camera, battery life shortens to 3-6 months. Such products often come with rechargeable lithium battery packs.
• Management Tip: You can check the real-time battery percentage via the mobile app, and receive multiple advance warnings for low battery.

Yes, but in a secure and controlled manner.

We strongly recommend using "One-Time or Scheduled Temporary Passcodes."Generate a passcode in the app that is valid for a set duration (e.g., 2 hours) or number of uses (e.g., 1 time), and share it via WhatsApp or other means. This solves the remote access need without disclosing permanent codes and avoids potential security risks associated with direct remote unlocking.

Without internet, core local functions work normally; connecting unlocks the full smart experience.

• Offline: All local unlocking functions like fingerprint, passcode, and key work perfectly, but features requiring the internet—like remote viewing, temporary passcodes, and alarm notifications—will be unavailable.
• Connection Methods: Connects to the home network via a Bluetooth gateway or Wi-Fi direct module. Once connected, you can access core smart functions like remote management, viewing access logs, and receiving abnormal alarm notifications.
