How do you unlock Oldsmobile Aurora stereo?

To unlock the stereo in an Oldsmobile Aurora, you typically need the radio unlock code, which can be found in the owner’s manual or obtained from a dealership using the vehicle's VIN. If the stereo is displaying a "LOCKED" message, turn on the ignition and leave the radio on for a set period (often around an hour) to reset it. After that, enter the unlock code using the preset buttons on the stereo. If you don't have the code, contacting a dealership or a professional car audio technician is the best course of action.
