SFW New Smart Lock Boxes Fingerprint Key Box with App Control - Secure

In this review of the SFW New Smart Lock Boxes, the bottom line is simple: this is a practical, multipurpose key storage solution for homeowners, rental hosts and caretakers who need flexible, secure access without complex installation. The unit combines fingerprint recognition, passcode entry, Bluetooth and an app that generates temporary passwords, so it covers most common entry scenarios. Setup is straightforward and customers report the fingerprint unlock and app features work reliably, making it a strong choice for anyone who wants a weatherproof, no-drill option to keep spare keys accessible to trusted people.

Key Features

• Multiple unlocking methods: Fingerprint, passcode, Bluetooth and an app give several fallback options so users are rarely locked out.
• Large fingerprint capacity: Stores up to 60 fingerprints so family members and frequent visitors can all have direct access.
• Flexible installation: Includes strong 3M adhesive and a hook design for door-handle hanging, plus optional screw mounting for a more permanent fit.
• App remote access: The mobile app generates one-time temporary passwords and shares keys, useful for guests, cleaners or service providers.
• Durable, weather resistant build: ABS construction with an IP54 rating stands up to rain, dust and temperatures from -20C to 60C for year-round outdoor use.
• Battery backup and monitoring: Runs on 3 AAA batteries with Type-C emergency power and app battery status monitoring to avoid unexpected lockouts.

Who It's For

This key box is best for homeowners who want a reliable outdoor key storage solution without drilling, vacation rental hosts who need to grant temporary access remotely, and families that prefer quick biometric entry for frequent users. The combination of fingerprint and app control fits situations where multiple people need secure, traceable access.

It is less suited for extremely high-security installations where a hardened safe or alarmed access control system is required, or for sites that demand fully tamperproof certified safes. Also, users who need only a simple mechanical lockbox and never intend to use app or biometric features may find this unit more complex than necessary.

Pros & Cons

• Weather resistant and durable ABS construction suitable for outdoor mounting.

Cons

• Not a substitute for a heavy-duty safe in very high-risk theft scenarios.
• Bluetooth and remote app unlocking are focused on temporary password generation rather than full remote unlocking in all modes.
