Smart Digital Door Lock - ST3 (5 - In - 1)
The ST3 Smart Digital Door Lock, offered by Wai Ming Metal Manufacturer Ltd. in Hong Kong, features a zinc‑alloy housing with a stainless‑steel deadbolt and measures 32 cm × 4.2 cm × 2.6 cm for both outer and inner bodies. It is engineered for doors with a thickness between 28 mm and 60 mm and weighs 1.80 kg. Power is supplied by four DC 6 V AAA alkaline batteries, and the lock supports Bluetooth mobile app control, fingerprint recognition for up to 120 users, PIN codes for 150 users, and an RFID tag system expandable to 200 tags. The unit also includes two mechanical keys for emergency access.
The lock’s construction combines a durable zinc alloy with a stainless‑steel bolt, a common combination for residential security hardware. Typical smart locks in this class meet an IP65 ingress protection rating and operate on a 5‑12 V DC range, which aligns with the ST3’s battery configuration. The bolt length is usually around 30 mm, meeting the standard ANSI Grade 2 requirement for residential doors. These industry standards ensure reliable performance across varied installation environments.
Ideal for property developers, security integrators and hotel operators, the ST3 suits both new builds and retrofit projects. Importers should request the supplier’s bulk pricing, MOQ and lead‑time details directly, as the listing does not disclose those figures. Verify the lock’s compatibility with existing door frames and confirm the battery type before placing an order. Payment terms and shipping arrangements can be negotiated once the supplier confirms availability.
