SZ20 Pro

The SZ20 Pro redefines the intersection of style and security. Designed with a recessed, concealed lock cylinder, this model offers a sleek, flush aesthetic that preserves the natural beauty of high-end wooden doors while providing superior anti-tamper protection. Available in a wide spectrum of color finishes, the SZ20 Pro is the definitive choice for B&B owners, hotels, luxury apartment managers, and homeowners who refuse to compromise on design alone.

Elite Management & Security Features:

• The Ultimate Rental Command Center: Engineered for the modern host. Generate and send digital passwords with a single click, set automated expiration dates for guest codes, and enjoy the peace of mind that comes with professional-grade remote management.
• Aesthetic Concealed Security: Unlike traditional bulky locks, the SZ20 Pro features a hidden, recessed lock cylinder. This “invisible” design not only enhances the visual appeal of your door but also provides a physical defense against forced entry and technical picking.
• Adaptive Access Suite: Provide your guests and family with flexible entry options: App Remote Unlocking, Fingerprint, Secure PIN Code, IC Card, or a discreet Mechanical Backup Key.
• Real-Time Safety Audits: Stay informed 24/7. Access comprehensive unlocking logs anytime and anywhere through the mobile app. Whether it’s a cleaning crew or a late-night guest check-in, you’ll know exactly when your door is accessed.
• Universal Architectural Fit: While optimized for wooden doors, the SZ20 Pro’s highly adaptable design is also suitable for steel frames, making it a versatile asset for diverse property portfolios.
• Type-C Emergency Resilience: Stay powered, stay secure. The integrated Type-C emergency port ensures that even if the batteries run low, you can provide instant backup power for your guests using any standard mobile power bank.
