Users of aluminum glass doors have all experienced the frustrating feeling: electronic locks quickly break down after only a few months due to rainwater, mold or component oxidation. Fingerprint sensors become less sensitive, touch keyboards freeze, and even locks suddenly lose power in the rain. Understanding that concern, OSUNO introduces to customers aluminum door locks that meet IP65 water-dustproof standards. Learn more below.
What is the IP65 standard?

The IP65 (Ingress Protection) standard is an international index that determines the level of protection of equipment against dust and water.
- Number 6: Completely dustproof, absolute protection for internal electronic components.
- No. 5: Effective against strong water jets from all directions, equivalent to heavy rain conditions.
Aluminum door locks are often installed on balconies, hallways, terraces or side gates, so meeting IP65 standards is a prerequisite for the product to operate stably and long-term. OSUNO aluminum lock lines such as OSN-3320, OSN- 3326/3326A, OSN- 2603 have all been tested to meet IP65 standards, ensuring smooth operation even in the rain or humidity up to 90%.
Why do aluminum door locks need to achieve IP65?

Vietnam’s climate is characterized by high temperatures, heavy rain, and high humidity all year round. With conventional electronic locks, rainwater can seep into the circuit board gaps, causing:
- Power failure, fingerprint sensor error.
- Touchpad freezes when wet.
- Batteries quickly fail due to water ingress.
At that time, users not only lose time repairing but also face security risks if the lock stops working unexpectedly. OSUNO lock with IP65 helps solve this problem: water resistance, dust resistance, comprehensive protection of internal components – ensuring safety for users.
Some waterproof techniques used in OSUNO aluminum door locks
OSUNO door locks meet IP65 – IP68 – IPX5 standards, providing complete dust protection and resistance to high-pressure water jets from all directions. This helps the lock to operate smoothly, minimizing electrical short circuits, rust or sensor errors. Therefore, users can rest assured to use it for a long time without worrying about the weather reducing the life of the device.
1. Tightly sealed lock body design
OSUNO lock housing is made from solid cast aluminum alloy, precision machining helps the joints to be tightly sealed, preventing rainwater from seeping into the circuit compartment. Some models also integrate waterproof rubber gaskets at the contact area between the body and the cover, increasing the effectiveness of moisture resistance.
2. Surface protective coating
The lock surface is powder coated and anti-oxidation treated, limiting metal corrosion, keeping beautiful color and ensuring stable operation in outdoor conditions for many years.
3. The circuit board is safely protected
All electronic components, sensors and control circuit boards are placed in a sealed compartment, avoiding direct contact with water vapor. Some high-end OSUNO models also apply a moisture-proof nano coating, helping the circuit board operate stably even when the air humidity is above 90%.
4. Meets IP65 – IP68 – IPX5 standards depending on product line
- IP65: Complete protection against dust and low pressure water jets – common on aluminum lock lines such as OSN-2603 , OSN-3320 .
- IP68: Waterproof when temporarily immersed, commonly found in high-end outdoor locks.
- IPX5: Resistant to medium pressure water jets, suitable for environments with frequent rain.
Thanks to the above solutions, OSUNO aluminum door locks not only ensure durable operation but also help customers feel secure in using them in many weather conditions – from storms in the North to salt air along the Central coast.
How to identify and properly preserve IP65 locks
- Check the OSUNO lock logo or packaging.
- Do not spray water directly with a high pressure hose.
- Dry the surface after rain to increase the durability of the coating.
- Periodically check the rubber gasket and battery cover.
OSUNO provides warranty and periodic maintenance services to help the lock always achieve maximum water resistance and maintain long-term quality of use.
Conclude
IP65 water resistance is not just a technical index – but OSUNO’s commitment to durability and safety for customers. With a streamlined design, high-quality materials and advanced waterproofing technology, OSUNO aluminum door locks are the right choice for spaces that require stability and safety in all weather conditions.
