Help! What happened?

:hmm: After parking my 2000 DeVille DHS it would not re-start. Nothing happened when I turned the key but the battery was fine and the lights worked. The interior lights would not shut off until the ten minute limit ended and the lights on the driver door panel would not go off at all. The auto door opener wouldn't even work. NADA! It started only after disconnecting the battery to let the computers recycle. What happened? How can I prevent this from happening again? HELP!!!

Was there any corrosion at the battery terminals? Corrosion at the battery can cause some bewildering electrical problems. Keep the terminals clean and tight.
On my 94, I did something one day that let me receive a message that the security system was disabling my car and I would not be able to start it. However, the time period that the security sytem had control was only 2-3 minutes. You waited at least 10 minutes and it still didn't start?

Can't think of anything else.
