Re: Procedure to unlock the radio

Ok ive got a 2012 Chevy Malibu that for one reason or another felt that the stereo needed to be locked. There was NO loss of power to the vehicle at all. I need to know how to get the code for this stereo so i can unlock it without having to take my car to the dealership. I dont know how much they will charge me but id rather not have to shell out money i dont have just to have my stereo working again.


HELP ME PLEASEEEEEEEEEEEEEEEEEEE!!!!!!!!!!
