Why Key Boxes Still Matter: Smart Key Management Trends in Short-Term Rentals and Real Estate
Why Key Boxes Still Matter:
As smart locks, mobile apps, and remote access systems become more common, physical keys may seem increasingly outdated. Yet across short-term rentals, real estate, and property management, Key Boxes continue to play an important role in key management and access control.
Key Boxes and smart locks are not simply competing technologies. They address different access needs. A Key Box allows properties to retain existing locks and physical keys while adding flexibility for temporary access, shared use, and key management.
From self check-in and property showings to cleaning and maintenance, the underlying challenge is the same: how can businesses provide secure, efficient access to different users at different times?
From Self Check-In to Property Showings:
Where Are Key Boxes Used?
Short-term rentals are one of the most visible applications for Key Boxes. Depending on the product design, guests can use a PIN code, Bluetooth, or a mobile app to access the Key Box and retrieve the property key without an in-person handover.
Real estate is another important application, particularly in North America. By keeping property keys securely on-site, authorized agents can access listings for property showings. The same concept can help property managers provide temporary access for cleaners, maintenance teams, and other service providers.
Industry data also illustrates the scale of this demand. According to Supra, its electronic access and key management system facilitates more than 70% of listing accesses, with over 32 million accesses annually and approximately one million real estate agents using the Supra eKEY app.
The figures are based on publicly available statistics and Supra-recorded lockbox openings through the eKEY app and hardware keys in the U.S. and Canada from 2019 to 2024. While these figures represent Supra's system usage rather than independent market-share research, they provide a useful indication of the role electronic Key Boxes play in North American real estate.
Why Do Key Boxes Still Matter in the Age of Smart Locks?
Smart locks change how a door is unlocked. Key Boxes address a different need: how to securely and flexibly share an existing physical key.
Short-term rentals, properties for sale, and managed buildings can vary in door types, existing locks, and access requirements. Instead of replacing the existing locking system, a Key Box can add another layer of key sharing and access management.
This flexibility becomes especially valuable when a property needs to be accessed by different users, including guests, real estate agents, cleaners, and maintenance teams. Temporary authorization, shared access, activity records, and installation flexibility can therefore become important considerations.
Rather than viewing Key Boxes and smart locks as a simple replacement relationship, businesses can select the right security solution based on usage scenarios, management models, and market requirements.
