I changed my battery and now my radio doesn't work. I bought the car used from a dealer 5 years ago. How do I get my stereo to work again.

Hello,

GM used an anti-theft device on these vehicles so when the power gets disconnected the radio locks.
Sometimes you will have to call the dealer with your VIN to get a unlock code. Other times it can be done with out dealer assistance.

I have attached step by step procedure for unlocking the radio.
If the display showing LOC then you should be able to use this process.

Please let me know of any questions.

Thank you.
