Immobilization prevents the car from being started until vehicle has been mobilized through Fetch. This feature is only available if the immobilizer was installed during your device installation.
To Mobilize / Immobilize your vehicle login to the dashboard by going to https://dashboard.fetchtruck.com. Navigate to the inventory page.
Select your vehicle from the list. In the upper right hand corner of the vehicle page you will see a button with three dots.
Select Immobilize / Mobilize from the drop down menu.
Once the vehicle has mobilized / immobilize, a success message will be displayed.
