I never owned a cavalier but have had the same problem with a Honda. I had to call the dealership that the car was origonally purchased at and prove that I was the owner then they gave me a code to enter into the stereo. If you don't know where it was origonally purchased you might try googleing the vin # and find out where the car came from. Often the code is in the owners manual for the car.
It means the radio is locked. You will have to insert the code to unlock the radio. You must have disconnected the battery or the battery ran down.
Check the manuals that came with the vehicle. There should be a card that has the code on it, or go to the dealership.
answer
Anytime a battery cable is disconnected you have to reprogram the set radio stations
It is the error you get when you have entered the wrong radio code three times. You need a code to unlock your radio if it has been disconnected from the battery i.e. if it was being stolen from your vehicle. Acura considers this an anti-theft device.

the is no code
When you disconnect a battery cable all the preset radio stations ( and the clock ) have to be reset
The battery has been disconnected. You will have to reenter the radio security code to reenable it.
with the motor running and radio off press buttons 1 and 4 on the radio this should unlock the radio
I have a 92 Honda accord with anti theft radio that needs a code when battery is disconnected. My code is 34444 if you have tried several codes that did not work you might need to disconnect your battery and reconnect battery again then try the code.
I meant to ask was the radio unlock code, after battery change
the radio was either pulled out or the battery in the car was disconnected at some point you have to go to an Oldsmobile dealer if you do not have the unlock code they will be able to look up off the vin number and walk you through the steps to unlock it
