2002 Oldsmobile Alero Q&A
2002 Oldsmobile Alero Question: Security light on dash and anti theft came on the radio.
Lets start with the no lights inside or out. Did you try to jump start the car? It sounds like the battery is discharged or dead. The question is going to be why is it dead. The radio could have gone into theft lock because the system lost power, that was common around 2002. (That can be turned off by the way). Before working with anything else you must have good system voltage or all bets are off. - cardocIII
Clean ALL battery cables and retighten. Pay close attention to the positive cables, clean those well. Common problem on this car!!! - pushrod
