All bTres units purchased through 9/15/2022 will marry to the first vehicle's VIN it's connected to. These units can be unlocked for a fee of $150 by the original purchaser plus shipping.
All bTres units sold after are either sold as locked or unlocked units at the time of purchase. I do offer a service to unlock it for a fee of $350 for the full bTres and $200 for the bTres mini. I do make some exception on occasion. Please reach out if you have any questions.
