Have you ever felt uneasy every time a sudden downpour splashes directly onto your balcony or main door? With ordinary electronic locks, rainwater intrusion often causes short circuits, erratic touch response, and expensive motherboard damage. Understanding this concern, OSUNO proudly introduces the super durable water-resistant aluminum lock OSN-3326 – the perfect solution for families to fully enjoy long Tet trips away from home in 2026 without worrying about unpredictable weather.
Why Choose a Specialized Water-Resistant Aluminum Lock?
For homes using Xingfa aluminum doors in positions directly exposed to the elements, choosing anything less than a dedicated water-resistant model like the OSN-3326 means risking:
- Motherboard failure: Water ingress can burn chips, leading to very costly repairs.
- Erratic touch functionality: The lock may unlock by itself or fail to read fingerprints during humid nồm weather or drizzle.
- Surface corrosion: Sea salt mist or acidic rainwater can ruin the aesthetic appeal of your home.
