What tool do you use to change configurations?

I know my 2007 Lexus has those programmable options like beep durations and such, but I have only found two solutions - paying the dealership $60 to change them, or buying a $15 android app that changes them. I could do it myself, but the codes (Lexus Personalized Settings) are secret. Did you find a free alternative to modify your Prius settings?

It is super easy on the Prius, this post goes through the steps:

But the short is someone else has done the hard work so you don't have to.
