  According to the owners manual:
  
  If a locked door is opened without the key or the remote
  keyless entry transmitter, the alarm will go off. The
  headlamps and parking lamps will flash for two minutes,
  and the horn will sound for 30 seconds, then will turn
  off to save the battery power
  
  So the horn doesn't sound for two minutes. Might be what you're running into.
