In order to sell your KTuner unit or return the unit, it is required that the unit is unlocked. This step-by-step guide is a tool to help you accomplish this process. Internet connectivity is required.
*Please do not purchase an locked unit! If the unit is locked and you're unable to unlock, reach out to KTuner direct. Non-original owners cannot purchase an additional license to have the unit unlocked.

Step 8: Unplug your KTuner unit from the OBDII port, then plug it back in. If you see this message pop up, then you have successfully unlocked the unit. Please take a photo of this as proof that the unit is unlocked.

Step 2: Plug the KTuner's cable into the unit and the laptop/desktop.
Step 3: Launch the KTuner software on your laptop/desktop.
Step 4: Upon opening the software, the following messages should immediately pop up:
If you do not have either one of those messages pop up, please select "Tools" and "KTuner Unit Info".
