5-in-1 Smart Padlock Guide: Fingerprint, RFID Card, Password, Key and Tuya App in One Lock

One Lock, Five Ways In: The 5-in-1 Smart Padlock

Shared-access environments face a constant question: which lock fits everyone? Keys get lost, codes get forgotten, cards get left at home. The SK-LD911 smart padlock answers with five unlock methods in one IP67 waterproof body — fingerprint, password, RFID card, mechanical key and Tuya App.

The Five Unlock Methods

  • Fingerprint – fast biometric entry with 50 fingerprint slots.
  • Password – 100 programmable codes for users, visitors and staff.
  • RFID card – 250 card users for badge-based access.
  • Mechanical key – 3 backup keys for emergencies.
  • Tuya App – Bluetooth lock and remote management from your phone.

Built for Heavy Shared Use

With up to 300 registered users, the SK-LD911 is designed for environments where dozens of people touch one lock every day: gym lockers, school lockers, warehouses, tool storage and gates. Each user can pick the method they prefer, and the admin controls who has access.

Weatherproof and Reliable

  • IP67 waterproof – fully protected against rain, splashes and dust.
  • Magnesium-aluminum alloy – strong, light and corrosion-resistant.
  • Double-lever locking – solid, pry-resistant construction.
  • Built-in lithium battery – up to 12 months standby.
  • Type-C emergency power – charge the lock or power it up with a USB-C cable when the battery is flat.

Why a Backup Key Still Matters

Even the best electronics can hit a dead battery or a forgotten password. The included mechanical keys guarantee the lock always opens — a simple backup that makes the SK-LD911 ideal for gateways, rental properties and emergency access points where downtime is not an option.
