It sounds like your battery is dead...
Get it charged, start the car, then check the alternator output to ensure it's upwards of 13volts (but less than 16), if it isn't you're just draining the battery when you drive.
I need a code to unlock the radio in my 98 bonneville.
relay is stuck...
Begin by removing the decorative cover from your 2001 Pontiac Bonneville radio. Remove the radio retaining screws. Slide the radio out and remove the wiring harness and the antenna cable.

You can replace the radio in a 2000 Bonneville with an aftermarket radio; however, the cost for the kits to make it work plus the labor could be cost prohibitive. The Bonneville's radio is connected to the computer. In fact if you replace the radio with an OEM, you still need to take the car to a dealership to have the new radio programmed. On top of that other electronic systems run through the radio wiring. Unless there is a very compelling reason, you would be better off to keep the factory equipment.
radio lol
Believe it or Not You have to Change your Spark Plug and Distributor Wires, to Noise suppressor type wires and probably put in a noise suppressor filter in the Hot wire that runs the Stereo. I know it sound different but this works.
Assuming it is functioning, turn the radio on.

turn the radio off
The most common cause of noise in your AM radio is a loose or corroded ground wire. Clean and tighten the ground wire and the AM noise should disappear.
