How do you get a RDS radio to unlock?

Question

I have a 2002 chevy malibu. and i recently brought a used rds radio from another malibu. But when the battery is off the radio works, when its hooked up it locks. And somebody told me you have to unhook the radio then try to get 2 sets of 3 digit codes but how can i, if the radio doesn't lock when disconnected. And Chevy wants to charge me $85-$130 to fix. I know its a simple problem. i just don't know what to do.

I have a chevy 2002 malibu. Recently i brought a used rds radio from another malibu. My radio says locked. but when its, i guess halfway hooked up it plays. But when you start the car it goes right back to locked. Chevy wants to charge me 85-130 dollars to fix the problem. But I know its one step im overlooking but i just can't figure out what i need to do to get my radio working. Please help me

Answer 1

The rds radio in your malibu can only be unlocked by you local GM dealership.Call you local dealership and see if they are any charge.The radio has to be unlocked with a tec-2 hand scanner.It will clear the bcm code and the radio will work ok.The dealer might need to relearn the new radio to the bcm for normal oreration.
