Executive Summary
This case study examines how a boutique hotel in Miami Beach, Florida successfully implemented a smart hotel lock system to overcome operational challenges and deliver measurable business results.
⭐At a Glance: Key Highlights
🏨Property Background
Located in Miami Beach, Florida, this 45 rooms boutique hotel represents a typical property in the boutique hotel segment. Like many properties in this category, it faced the challenge of balancing guest expectations for modern technology with operational efficiency and budget constraints.
Prior to implementing the smart lock system, the property relied on traditional access control methods that, while functional, created friction points in the guest journey and imposed unnecessary operational overhead on staff.
⚠️The Challenge
A trendy boutique hotel in Miami Beach's Art Deco district struggled with long check-in queues during peak season (November-April), guest complaints about lost key cards, and high front desk labor costs.
The traditional magnetic stripe key card system had a 15% failure rate, leading to frequent guest disruptions and negative online reviews. During peak season, average check-in time reached 12-15 minutes, creating lobby congestion and frustrating time-pressed travelers.
The property was spending $3,200 annually on replacement cards alone, not including the hidden costs of staff time handling lock-related issues.
Key Pain Points Identified
- ▸Guest experience friction due to traditional access control limitations
- ▸Operational inefficiencies consuming valuable staff time and resources
- ▸Lack of data visibility and real-time insights into access patterns
- ▸Competitive disadvantage in attracting tech-savvy travelers
These challenges were costing the property both in direct expenses (staff time, replacements, service calls) and indirect costs (guest dissatisfaction, negative reviews, lost revenue opportunities). Management recognized that modernizing the access control system was no longer optional—it was a competitive necessity.
💡The Solution
Implemented Salto KS (KeySafe) mobile-first smart lock system with BLEnet wireless technology, integrated seamlessly with Mews PMS via native API.
The solution enables contactless check-in, mobile room access via Salto JustIN Mobile app, and automated digital key distribution via email 24 hours before arrival.
System includes real-time access monitoring, battery status alerts, and cloud-based management dashboard. Mobile keys can be shared with travel companions and expire automatically at checkout. Integration allows for early check-in flexibility when rooms become available, with instant mobile key activation.
