To unlock the stereo in a 1998 Buick Riviera, you typically need the radio code, which is often found in the owner's manual or the original purchase paperwork. If you don't have the code, you can try contacting a Buick dealership with your vehicle's VIN, as they may be able to provide it. Alternatively, some aftermarket stereo systems might have a reset button or require a specific sequence of button presses to unlock. If you're still having trouble, consider consulting a professional technician.
