Forgot security pattern to unlock admin profile in infotainment system.
I wanted to post a follow up for my case of a removing an unknown pattern lock in my Silverado EV (I bought the Silverado used with a lock already set).
Apparently OnStar would normally be able to remove the lock remotely by creating a new account and then deleting the old one. In my case OnStar could not see the account with the lock and will require a visit to the dealer to apply TSB Bulletin No.: 25-NA-340 (November 2025) "Clearing Radio PIN from Vehicle with RPOs IVD, IVE and IOK".
My dealer service advisor was not aware of the TSB when I visited them about the problem and it took a month of going back and forth with OnStar for OnStar to figure it out. I have the appointment with the dealer scheduled so hopefully it'll finally get fixed.
