Vacation rentals have been booming for several years, driven by platforms like Airbnb, Booking.com, and Abritel. In this context, managing guest arrivals and departures has become a major challenge for property owners and managers. The key box, often mounted outside the property, has long been the preferred solution for contactless key collection. However, this method is not without its drawbacks: limited security, an impersonal guest experience, easier access in the event of code theft, and more. Many alternatives have emerged that are more secure, technologically advanced, and adapted to the new expectations of travelers.
In this article, we will review the main alternatives to the key box, explaining their advantages and disadvantages, and when they are most suitable.
1. Connected locks: an alternative to the key box
What are they?
Smart locks replace or complement traditional locks and allow you to open the door using a mobile app, a code, an RFID badge, or even a fingerprint.
Benefits:
Enhanced security : automatic code changes between tenants, access log, and instant access cancellation.
Zero physical contact : ideal in the post-COVID era or for international travelers.
Smooth customer experience : no need to search for a key box; travelers receive instructions directly on their phone.
Disadvantages:
Installation cost : A smart lock can cost between €150 and €400, not including the possible subscription fee for certain features.
Technology dependency : Unstable Wi-Fi or dead batteries can cause problems.
Compatibility : Not all doors or locks are suitable.
Popular brands:
2. The digital code (stand-alone digital lock)
What is it?
It's a box installed on or near the door that unlocks access using a code. Unlike a key box, it doesn't store a physical key.
Advantages:
Ease of use : travelers receive a 4- or 6-digit code.
No risk of losing the key.
Easy to install and often more discreet than a key box.
Disadvantages:
Less secure than a smart lock if the code remains unchanged.
Risk of failure (batteries, electronic components).
Tip:
Choose a keypad entry system that allows for remote or automatic code changes with each new booking to prevent unauthorized access.
3. Smart digital safes
What is it?
Unlike simple mechanical key boxes, these models are connected to the internet and allow remote control via an app.
Benefits:
Advanced features : opening alerts, access history, limited access time.
Ideal for multi-property managers.
Disadvantages:
Even more expensive than a traditional key box (€200 to €500).
Requires a certain technical infrastructure.
This type of system is a good compromise for those who wish to keep a physical key system, while benefiting from an increased level of security.
4. In-person check-in with concierge or local host
What is it?
A professional host or concierge welcomes guests on-site upon arrival, hands them the keys, and provides them with necessary information.
Benefits:
Warm and personalized welcome.
Less risk of technical or access issues.
Allows for a genuine customer relationship, leading to better customer reviews.
Disadvantages:
Less flexible (arrival time must be respected).
High cost, unless the owner arranges it themselves.
Not viable on a large scale without professional concierge services.
Who is it for?
Ideal for high-end accommodations or hosts wishing to offer 5-star service.
5. Automated check-in services at relay points or stores
What is it?
Some services allow you to drop off keys at partner businesses (bakeries, tobacconists, laundromats) or at secure lockers in town.
Examples of services:
City CoPilot
Advantages:
No home installation required.
Flexible hours, often open late or 24/7.
Good solution in dense urban areas.
Disadvantages:
Not yet widely available in rural areas.
Dependence on a third-party service provider and store hours.
Less personal than on-site reception.
6. Integrated home automation systems
Some owners go further by integrating their access solution into a complete home automation system: alarm, cameras, motion detectors, opening sensors, etc.
Benefits:
Complete monitoring of property access and security.
Automation of check-in/check-out (lights, heating, etc.).
Can be paired with platforms like Airbnb for automatic synchronization.
Disadvantages:
High investment.
Complexity of implementation for non-techies.
Maintenance required.
Which alternative to choose?
The choice depends on several criteria :
Budget : A smart lock is more expensive than a simple digital code.
Type of accommodation : Urban apartment vs. detached house.
Rental frequency : Regular or occasional rentals.
Desired level of service : Simple, independent access or personalized welcome.
Traveler profile : Young travelers, families, international travelers, or seniors.

Whether you're an occasional host or a short-term rental professional, it's time to rethink your access system to combine modernity, efficiency, and customer satisfaction.
Take the time to assess your needs, your budget, and the specific features of your property. A good access system not only provides peace of mind for you, but also a powerful tool for improving your reviews, your reputation, and your bookings.
