Lianshi Alarm Lock 110dBA – Universal Security Lock System (2 Pack)

Reliable, multi-surface security with the Lianshi Alarm Lock

The Lianshi Alarm Lock blends a loud 110dBA alarm with rugged hardware, designed to deter tampering and provide a clear signal when activity is detected. It’s built to adapt from doors to bikes, gates to containers, giving you a versatile option for everyday security needs.

Two modes for flexible protection

This system can operate in two states: a mechanical lock or an alarm-enabled lock. To switch modes, rotate the latch left or right and slide it into the lock body. The dual-mode design lets you balance convenience with deterrence as situations change.

• 110dBA alarm activates on movement or tampering, delivering an immediate audible deterrent.
• Low false alarm rate: the device emits two quick beeps at first, then a single follow-up signal after 11 seconds to conserve power.
• Heat-treated, hardened latch is abrasion resistant and rust-free; core diameter 0.39 inches with a latch height of 1.7 inches.
• Anti-tamper and robust construction aim to discourage casual interference while maintaining practical daily use.

Wide range of practical uses

Compact enough for doors, windows, bicycles, motorbikes, pull gates, and garden enclosures, yet sturdy enough to handle regular outdoor or indoor environments. The audible alert helps you notice activity without hesitation.

• Ideal for urban apartments, shared spaces, or rural setups where quick deterrence matters.
• Includes two alarm locks with multiple keys and batteries for straightforward setup and operation.

What’s included

2 alarm locks, 6 keys, and AG13 button batteries are included to help you set up right away. Each unit features a round core and a heavy-duty latch, designed for reliable everyday use.
