First a brief history for the 2001. A few months age the ignition switch was replaced and last month it got t boned on the drivers side and back. When the ignition switch went some of the wires were melted in the steering column. The accident just pushed in the door panel enough to stop the window from working. Most of the damage was behind the door and rear fender. My daughter park the car and came out the next day and her radio was still on and said her remote wouldn't work when the radio was on but if she turned it off it would lock. She parked it for 3 days and the battery was dead. I think she left the radio on with the cassette tape in which has a cord to her phone for her music. That probably drain the battery. I got the battery charged and back in the car. with the window down and car locked I went back out 2 hours later and was able to turn the radio on and off. I did noticed that with the window down something is loose in the door so its going back to the body shop. When i first got it home I did shut the door with the window up a few times and the remote stopped working,turning the radio on and off did not change to allow the remote to start working so I turn the key on and off on it locked the doors. I hope that what ever is loose in the door is messing with the remote. Should the radio work with out the key in forever. the most I can find is 20 minutes to an hour is normal.
