Smart Key Lock Box Electronic Bluetooth Lock Box with APP Control

Our review of the Smart Key Lock Box finds it best for homeowners, Airbnb hosts, and realtors who need controlled, temporary access without changing locks. The biggest reason to buy is simple: the TTLock app plus PIN and eKey sharing gives minute-specific, time-limited access while the weatherproof zinc alloy body keeps keys secure outdoors. This review focuses on practical use, covering setup, durability, battery backup options, and the daily convenience of generating virtual passwords for guests or service workers.

Key Features

• App control: The free TTLock App lets users create and manage eKeys and virtual PINs so access can be granted or revoked remotely for precise time windows.
• Anti-peep PINs: The keypad accepts anti-peep virtual passwords (6-9 digits) which reduce the risk of accidental code disclosure while maintaining simple keypad entry.
• All-weather construction: The zinc alloy body with IP65 rating protects contents from water, dust, and temperatures from -20C to 55C, making it suitable for outdoor wall mounting.
• Battery and emergency power: Powered by 3 AAA batteries with app low-battery alerts, and a USB-C port allows temporary power from a power bank to avoid lockouts.
• Spacious interior: The reinforced interior fits multiple items, roughly up to five keys, three access cards, and a car key fob, keeping small essentials organized and protected.
• Access sharing: Create temporary, minute-specific codes ideal for short-term rentals and contractors to speed up key handover workflows.

Who It's For

The Smart Key Lock Box is aimed at homeowners who want to avoid hidden spare keys, Airbnb hosts who need quick guest turnover without in-person check-ins, and real estate agents or property managers who coordinate entries across multiple units. The app-based sharing and code expiry are especially useful for short-term rental hosts and maintenance teams.

People who need full remote internet-based control from anywhere should look elsewhere, since the lock uses Bluetooth and the TTLock app and does NOT include native WiFi. Also, users who prefer integrated smart-home WiFi features or professional-grade commercial safes may find this unit too simple for large-scale deployments.
