Operation

Setting up Locked is incredibly quick and easy

Install the app

Download and install the Locked app on your mobile phone.

Turn on the device

30 seconds after the power button is pressed, Locked will activate, indicated by several flashes of its front light.

The alarm works by measuring the compass direction that the alarm is facing. When turned on it will measure its current heading and activate if it deviates by 10 degrees. When activated the alarm sounds a siren and sends you a text message.

Hook it on your door

Thanks to simply designed hooks, attaching Locked to any door is made easy with no extra setup required. That's it!
