FAQ – Smart Locks for Sliding Glass Doors (2025)
1. Can I install a smart lock on any sliding glass door?
Most models fit standard aluminum or uPVC frames. Always verify your door’s stile width before purchasing — some locks require mortise installation.
2. Are smart locks safe for outdoor use?
Only models with a high IP rating (IP54–IP66) are suitable for outdoor exposure. For uncovered patios, choose an IP66-rated lock for optimal weather resistance.
3. What is a double hook mortise mechanism?
It’s a locking system that anchors the door at two vertical points, preventing prying and lift-out attacks — essential for glass sliding doors.
4. What happens if my smart lock battery dies?
Most modern smart locks include USB-C emergency power ports or mechanical keys for manual access.
5. Are fingerprint locks more secure than keypad or card locks?
Yes — fingerprints are harder to duplicate than IC cards, but always ensure the sensor uses encrypted storage to protect biometric data.
Conclusion
Smart locks for sliding glass doors have matured into advanced, multi-layered security solutions. In 2025, physical integrity remains the core of true protection, with digital convenience serving as an enhancement — not a replacement.
For the most balanced protection, choose a double hook mortise smart lock like the Dhiedas or Anweller D208F. For low-maintenance or backup entry points, the mechanical keyless combination lock remains a timeless, tamper-proof solution.
