Lianshi Alarm Lock 110dB Security Alarm System – 2-Pack Anti-Theft Lock for Doors, Bikes & Padlocks (3 Keys per Lock)

Overview

The Lianshi Alarm Lock combines a loud, 110 dB audible alarm with a robust latch, designed to deter tampering and alert you when movement is detected. Built for daily use, the lock emits a powerful sound when it’s bumped or shaken, helping you notice activity in real time. The hardened latch and compact core deliver a sturdy, abrasion‑ and rust‑resistant component that feels dependable in everyday scenarios.

Two security modes

Choose between a mechanical lock or an alarm mode. By flipping the latch direction, you switch between states and adapt to the situation. The system aims for low nuisance alarms: a brief two‑beep signal on initial movement is followed by an eleven‑second quiet period to conserve power, then it resets for continued readiness.

Durable construction and size

Heat‑treated, hardened steel latch provides abrasion resistance and rust protection. The latch measures a round core diameter of 0.39 inches with a height of 1.7 inches, delivering a compact yet solid profile suited to doors, windows, bikes, and outdoor fixtures.

Versatile use and packaging

Designed for a range of applications—from doors and windows to bicycles, containers, motorbikes, tricycles, gates, and garden entrances—the kit includes two alarm locks, six keys, and twelve AG13 button batteries, ensuring you can set up and share access right away. Each lock offers three keys, totaling six keys for the two locks.

Practical considerations

While no single device guarantees complete security, the Lianshi Alarm Lock provides an audible deterrent and a tangible physical barrier. Its two‑state design offers flexible security planning, and the included batteries and keys support ongoing use in shared spaces or multi‑user setups.
