As soon as someone tries to tamper with it or unlock it without the original key, the alarm will activate along with the 110db siren. It will scare off the potential burglar. Ideal for doors, machines, bicycles, tools, and cars, it offers limitless applications. Made from durable metal material.

Once you lock the padlock, the alarm notifies you with a distinctive sound that it has been activated, giving you 15 seconds to remove the key from the lock. After 15 seconds, and once the vibration sensor "feels" 2 or more vibrations within 5 seconds, it activates the alarm and remains active as long as vibrations persist.

• Operates with 6 A76/LR44 1.5V batteries.
