Sliding Door Smart Lock Guide: Outdoor Waterproof WiFi Fingerprint Lock for Gates and Aluminum Doors

Sliding Door Smart Lock: Outdoor Waterproof Keyless Entry That Fits Any Door

Courtyard gates, sliding glass-aluminum doors and main entrances share one problem: weather. The SK-X2 sliding door smart lock is IP68 waterproof and unlocks with fingerprint, PIN, card, key or the Tuya / TTLock App over WiFi.

Weatherproof by Design

With IP68-rated waterproofing, the SK-X2 takes rain, spray and coastal moisture in stride. The zinc alloy body resists corrosion, and the C-grade cylinder stands up to physical attack.

Five Ways In, One App to Rule Them
