Answer 1

Try disconnecting the positive battery cable and re-connecting it. Or leave it hooked up, insert your key in the drivers side front door, turn it slowly to the lock position, hold it there for a second or two, release it to the neutral position, turn to the unlock position slowly, then release it to the neutral position. That should disarm or reset the alarm.

Answer 2

if that doesn't work take the negative cable off and try erasing it completely,this should reset it,i have had to take the negative cable off several times to get those to start back,that night work also,good luck.
