With Tet Nguyen Dan 2026 approaching, theft incidents typically rise as families travel for extended periods—visiting relatives, vacationing, or celebrating the Lunar New Year. In reality, traditional mechanical locks on iron gates remain one of the most vulnerable security weak points: easily picked, forced open, or degraded by Vietnam’s harsh rain, sun, and humidity. Installing a high-quality waterproof fingerprint gate lock has become a popular upgrade among homeowners, landlords, homestay operators, and rental property owners. It provides robust asset protection, precise access control, and peace of mind during the holiday season. Amid the wide range of options available in 2026, which solution truly delivers reliable waterproofing, long-term outdoor durability under partial shelter, and strong investment value? This article, from OSUNO’s expert perspective, provides clear, objective guidance.
Why Upgrade to a Fingerprint Gate Lock Before Tet 2026?
Year-end periods heighten security risks while increasing visitor traffic for family gatherings and festivities. A premium fingerprint gate lock delivers three key practical benefits:
- Peace of Mind While Traveling: Theft patterns often intensify during Tet. Advanced anti-tampering features, intrusion alerts, and biometric security ensure your property stays protected during prolonged absences for hometown visits or trips.
- Convenience for Guests and Family: No need to duplicate mechanical keys for relatives or visitors. Temporarily grant access via a one-time code or app-based authorization—even if you’re not home yet.
- Elevated Property Appearance: A modern smart lock on an iron gate or Xingfa aluminum system enhances curb appeal, projecting a sophisticated, contemporary image that aligns with welcoming prosperity in the new year.
Comparison: Traditional Gate Locks vs. OSUNO Fingerprint Gate Locks
Many households hesitate between sticking with mechanical locks or upgrading. Here’s a clear side-by-side comparison highlighting the performance gap in 2026:

| Criterion | Traditional Mechanical Gate Lock | OSUNO Fingerprint Gate Lock |
| Security Level | Vulnerable to master keys, picks, or acid attacks; keys easily duplicated | Biometric fingerprint (non-replicable); high-grade anti-copy mechanical backup |
| Convenience | Requires carrying bulky key sets; risk of loss or forgetting | Multiple methods: fingerprint, card, passcode, mechanical key, TTLock app |
| Weather Durability | Prone to rust, jamming after rain/storms; requires frequent lubrication | Premium alloy construction, waterproof/dust-resistant under shelter; no oxidation issues |
| User Management | Adding users requires duplicating keys; changing security means replacing the entire lock | Quick add/remove fingerprints on-device; ideal for changing helpers or tenants |
| Security Alerts | Passive—no notification of tampering | Loud built-in siren for forced entry or repeated failed attempts |
