You would need to pay to unlock the device for $250 unfortunately. It is important to return your previous vehicle to stock if you plan to keep the device and use it on your next vehicle before selling.
We have exceptions for Totaled Vehicles or Vehicles that have had dealership work done that flashed the ecu but proof would need to be provided that matches the information the device is married too.
If you would like to inquire further, on this contact us at contactsales@derivesystems.com or visit our chat option and select Sales.
