304 Stainless Steel Smart Lock: IP68 Waterproof Keyless Entry That Lasts
Coastal homes, steel gates and high-traffic entrances need a smart lock that won’t rust or fail in the rain. The SK-X9 304 stainless steel smart lock is rated IP68 waterproof and unlocks five ways — fingerprint, password, card, mechanical key and the TTLock or Tuya App.
Built From 304 Stainless Steel
The body is machined from 304 stainless steel — the same grade used in marine and kitchen hardware — so it shrugs off corrosion, salt air and decades of daily use. The C-grade cylinder resists picking and drilling.
Five Ways to Unlock, One App to Manage
Use your fingerprint, a PIN, an RFID card, the mechanical key or the app. With 100 user profiles and cloud storage, you can add family, staff or tenants and review access records from anywhere.
IP68 Protection, Emergency Power
IP68 means the lock is sealed against dust and can survive immersion — ideal for exposed gates and rainy climates. If the four AAA batteries ever run flat, the Type-C port brings the lock back to life in seconds.
Tested Like a Premium Lock
Every SK-X9 passes an 8-hour PCB aging test, 72-hour high-low temperature cycling, 96-hour salt spray testing and a 200K-unlock standard — backed by CE, FCC, RoHS and ISO certification.
Where the SK-X9 Works Best
- Coastal homes and villas – salt-resistant stainless steel.
- Steel and copper main doors – premium look, real security.
- Offices and apartments – 100 profiles for staff and tenants.
- Outdoor gates – IP68 waterproof confidence.
