1. Measure Before Buying: The guide plate size, door thickness, and lock body type are the three key factors you must understand before purchasing.
2. Consider a D-hook/Hook Lock: For a stable and longer-lasting Fingerprint Scanner, it's recommended to forgo a D-hook lock and choose one with a hook lock body.
3. Professional Installation is the Best Option: Leave professional tasks to professionals to avoid problems during DIY installation.
4. Thorough Post-Installation Testing: Ensure both mechanical and electronic functions are present to guarantee complete functionality.
5. Safeguard Emergency Supplies: The mechanical key and combination card must be kept in a safe place outside your home.
