How does Car Alarm work?

For the Car Alarm app to work, it needs to be installed on at least two iOS or Android devices:

Main Device, which receives notifications

Remote Device, which is placed inside your vehicle.

Start the Car Alarm app on both devices, log into your app account with your email and password, and choose the car. You have 15 seconds to place the Remote Device and leave the car before the Watchdog mode kicks in.
