Description
Heavy-Duty Smart Padlock with Fingerprint, App & Key Unlock

Upgrade from a conventional padlock to smarter, keyless access with the SmartX SX-PL916 Heavy-Duty Smart Padlock. Designed with a robust zinc alloy body and A3 Steel Shackle, this smart padlock combines fingerprint recognition, TTLock App control and mechanical key backup in a larger, heavier-duty design.
Unlike battery-powered models that require battery replacement, the SX-PL916 features a built-in rechargeable battery with Type-C charging, making it more convenient.
Multiple Ways to Unlock
The SX-PL916 gives you three practical unlocking options:
- Fingerprint Unlock – Unlock using your registered fingerprint.
- TTLock App Control – Manage and control the padlock through the TTLock App.
- Mechanical Key Unlock – Keep a physical key as a backup access method.
With support for up to 50 fingerprint users, the lock can be suitable for personal, family, office and shared-access applications.
Built-In Rechargeable Battery with Type-C Charging Port

One of the key differences of the SX-PL916 is its built-in rechargeable battery.
Instead of replacing disposable batteries, simply recharge the padlock through its Type-C charging port when required. The specified standby time is up to 180 days, depending on usage and operating conditions.
This makes the SX-PL916 particularly convenient for locations where occasionally replacing batteries would be inconvenient.
TTLock App Smart Access
The SX-PL916 works with the TTLock App, providing smartphone-based smart lock management.
The App can be used for compatible lock management and access control, while the padlock’s Bluetooth-based smart functionality eliminates the need to rely solely on a physical key for everyday access.
IP67 Water & Dust Protection

With an IP67-rated design, the SX-PL916 is designed to provide strong resistance against dust and water exposure.
However, IP67 protection does not mean the padlock should be intentionally submerged or exposed unnecessarily to harsh environmental conditions.
Heavy-Duty Construction
The SX-PL916 has a 0.6 kg net weight and a 107 × 65 × 30 mm body, making it noticeably larger and heavier than the SmartX SX-PL705.
Its body is constructed from zinc alloy and the shackle A3 Steel, while the specified tensile strength is up to 800 kg.
This combination makes the SX-PL916 a suitable option when you are looking for a more substantial smart padlock rather than a lightweight compact model.
50 Fingerprint Capacity
The SX-PL916 can store up to 50 fingerprint groups, allowing multiple authorized users to access the lock without sharing a physical key.
This can be useful for:
- Homes and gates
- Offices
- Shops
- Warehouses
- Storage areas
- Lockers
- Equipment and utility areas
- Shared-access locations
