YINTIN Heavy Duty Fingerprint Smart Padlock with Keypad Combination Lock

Technical Specifications

• /HEAVY-DUTY SMART LOCK — Built with a zinc-alloy body and hardened steel shackle, this smart padlock combines a solid, modern design with flexible everyday access for gates, storage areas, toolboxes, and shared spaces. Fingerprint, RFID card, keypad code, app, and temporary-code access reduce the need to carry a key during daily use, while 2 included mechanical backup keys provide an alternative way to unlock it when needed.
• /SIX FLEXIBLE UNLOCKING OPTIONS — Open by fingerprint, RFID card, keypad code, Tuya Smart or Smart Life, temporary code, or backup key. The sensor recognizes enrolled fingerprints in about 0.5 seconds and stores up to 50 fingerprints.
• /APP PAIRING AND MANAGEMENT — Press # or touch the sensor to wake the lock. In Tuya Smart or Smart Life, tap + and Add Device, then follow the prompts. Bluetooth sleeps when idle; Wi-Fi remote unlocking needs a compatible gateway, sold separately.
• /IP67-RATED OUTDOOR PERFORMANCE — The sealed housing is designed to resist dust and water and operates from -4°F to 122°F. A 500 mAh battery offers up to 12 months of standby time, with low-battery alerts and USB-C emergency power.
• /⚠️REQUIRED FIRST-TIME SETUP — Wake and pair the lock through Tuya Smart or Smart Life, then enroll at least one administrator fingerprint before use. Until enrollment is complete, factory mode accepts any fingerprint; this is normal setup behavior.
• /⚠️ CHOOSE THE RIGHT SIZE BEFORE ORDERING — This smart padlock has a larger body than a typical small padlock (5.2 × 2.2 inches) and is designed for more demanding security applications, such as outdoor gates, storage rooms, sheds and toolboxes. It may not fit lockers, cabinets or other small openings. Available with 9/32-inch (7 mm) and 3/8-inch (10 mm) shackles. Please measure both the lock-body clearance and shackle opening carefully, and confirm that the size and intended use meet your needs before placing your order.
• /READY FOR SHARED ACCESS — View access logs and create temporary or recurring permissions for family, guests, or staff. Includes 2 RFID cards, 2 backup keys, a USB-C cable, and a one-year limited warranty. For product support, contact us through Amazon Buyer-Seller Messaging.
