When should I buy a VIN reset code?
Buy a VIN reset code only when the tuner is VIN-locked to a vehicle and the root code is displayed on-screen. If the tuner is not locked, you may need a first-tune code instead.
Will this work if my root code changed?
Root code based orders are tied to the value shown during checkout. If the code changes, you will need to place a new order with the updated code. Remember to keep your tuner powered on and stay on the root code screen until checkout is complete.
