Smart Key Box with Fingerprint Password Card Bluetooth Access Control for Office Rental

Managing keys for multiple users at an office, rental property, or shared access point often leads to lost keys, inconvenient handovers, and security gaps. This smart key box provides a centralised solution using fingerprint, password, card, and Bluetooth app access, so you can grant or revoke entry without physical contact. Its ability to store up to 100 fingerprints, 150 cards, 1000 faces, and 150 passwords makes it suitable for high-traffic environments where many people need brief or regular access. The device operates on a 12W power supply and functions between -25°C and 55°C, ensuring reliable performance in varying conditions.
Features and Construction

The key box is built with durable ABS plastic and integrates multiple sensing technologies for flexible security setup. It communicates via Bluetooth for app-based configuration and can be used with common access cards operating at 13.56 MHz or 125 kHz. The K3BF and KB5F models offer TTLock or TTLock+ Gateway styles, allowing you to choose the connectivity level that fits your building or property management system.
Material and Build
The ABS plastic housing provides a lightweight yet sturdy enclosure that resists minor impacts and wear. It is designed to be wall-mounted or placed in a secure location, protecting the internal electronics from dust and occasional moisture. The keypad and fingerprint sensor are built for regular daily use, with touch-sensitive controls that respond reliably.
Size and Practical Fit
While exact dimensions are not specified, the unit is compact enough to fit near doorways, in entrance halls, or on office reception desks. Installation requires only a 12W power source and Bluetooth connectivity to a smartphone for initial setup. The key box can be mounted vertically or horizontally, depending on wall space and convenience.
Uses and Placement

This smart key box is most practical where multiple people need temporary or permanent access to keys or secured items. Common placements include beside entrance doors, in rental property entryways, or within a security cabinet at a workplace.
Event or Professional Use
In event venues or co-working spaces, the key box allows staff to access keys only when authorised, with a clear audit trail via the app. The high card capacity (150 cards) and password slots (up to 150) make it easy to assign temporary credentials for contractors, cleaners, or visitors without giving out master keys.
Everyday Home Use
In a domestic setting, family members can use fingerprints or a personal code to retrieve keys, while the app logs each opening. The Bluetooth range covers typical home distances, so you can check who accessed the key box from your phone, even when away.
Benefits and Buying Value

The key box reduces the need for physical key handovers and eliminates the risk of keys being copied or lost. Its large memory capacity means it can serve a growing number of users without needing hardware upgrades.
Reuse and Low Maintenance
Once installed, the key box requires minimal maintenance apart from occasional battery checks (if using battery backup) and surface cleaning. The electronic lock mechanism is rated for many cycles, requiring no lubrication or adjustment. Firmware updates can be pushed via the app when available.
Why Choose This Product
For property managers or landlords, this key box streamlines key control across multiple tenants or staff. The combination of fingerprint, password, card, and app options ensures that even if one method fails, users can still gain access via an alternate route. The TTLock+ Gateway model adds remote control capability, making it a future-proof choice for smart home or commercial systems.
