If you went to Auto Zone, they do check your SES codes for free. What I do is if they don't want to reset it is that I tell them that they can either do it themselves or, since it is a free service, that I am going to rent the code scanner come out and reset it myself then bring it right back in. In essence you would be waisting their time in the refundable deposit that they have to process and then reversing it when you come back in. Works every time.
