I had the same problem with my car. It was something to do with the serial power network in my car. The Instrument cluster along with my stereo on my 2005 cobalt died.

I ended up replacing the instrument cluster and radio. The instrument cluster didn't have to have the VIN programmed into it, but the stereo did.

If it says "LOC", call you're local GM service center and have them unlock it. It cost me $54 dollars to get it done.

There is a code in the owners manual packet that came with the car, it has instructions and the code, if you don't have this material call the dealer withe the VIN of your car and he may be able to provide the code.

You will have to go to dealer to have unlocked. The vehicle has built in theft lock system in radio. Most of them have code stored in radio that needs to be pulled before removing battery.

My car radio and CD is not working at all when i change battery.


some cars have security in the radio and if it was turned on when you unhooked the battery the radio probably lost the code. unfortunately you will probably need to take it to a dealer to get the radio unlocked.

I unhooked the battery and upon replacement of the battery the radio is not working


If the stereo has CODE written across the screen you need to enter the security code which is usually on a plastic credit card style card which is found in the owner service and manual pack. Or it may just be written somewhere in the pack.

My 2004 hyundai has a check engine light on with a code p1520. I clear the code and it comes back on and my car goes into fail safe mode.


P1520 Generator Front Terminal Malfunction is what that code means. you need to fix that issue as clearing the code and not fixing it will just cause the check engine light to keep coming on.

i would suggest unhooking the battery. cleaning the terminals and hooking the battery up again... if you have an antitheft radio make sure you know the code and how to enter it before you unhook the battery.

Radio won't reset. i have the code but nothing ha...


If the wrong code is entered a few times it won't take one at all. Unhook your battery for about an hour and try again.
