Anyway you most likely will need an ac person to come out and unlock it unless you can find how to do it on you tube. You can find everything there.

As a retired commercial plumbing and heating contractor, you are correct. Most of the time they are trying to scare you so they wont have to fix or adjust something, falsely claiming "it will void the warranty".
