HOW DO I RESET MY ONSTAR PIN?

A PIN is needed to access some OnStar services, like Remote Door Unlock and Stolen Vehicle Assistance. You will be prompted to change the PIN the first time when speaking with an Advisor. To change the OnStar PIN, call OnStar (1.888-4ONSTAR) and provide the Advisor with the current number.
