Re: Access key
I’m not entirely sure I understand the issue you’re describing. There isn’t a passkey required to access the TCU.
You can enable a read lock on the TCU to prevent the base file from being read. If needed, this lock can be removed by unchecking the option and reflashing the TCU. This setting does not prevent you from flashing the TCU—it only blocks reading the file.
If you’re referring to TunerPro prompting for a registration key when it opens, you can safely ignore that message and simply click “Continue.”
