Malibu LT 2004. I am contacting from Mexico. I need to know how to unlock the radio for my Malibu 2004, this one is the 6 disc in dash model. I bought it to replace the original which was stolen. I don´t have any codes or anything to help.
I read your answer for a chevy Malibu 2000 but that method did not work on mine maybe because the radio is different. If you need to ask for the backup codes, just let me know how to get the factory scramble codes and I will send you a donation for your help.
Answer: Unfortunately this radio does not unlock as in prior model years. The process of getting a code from the radio and then entering a factory backup does not work anymore. That type procedure ended for most GM vehicles in the 2000 model year.
Nowadays the only way to unlock a radio is with dealer scanner tool. The radio needs to be "set-up" for the VIN of the car it is installed in. This VIN set-up procedure with the scan tool sets the VIN #, speaker option, volume levels, etc.
