is it a factory alarm with the separate key in the drivers quarter panel? most alarms will rearm if their set off and allowed to cycle through without being turned off. try locking and unlocking the door with your key. if your alarm is oem it should have gone off when you opened the hood. aftermarket alarms will go off when they first get power to them. like if you disconnected the battery then reconnected it, that would set off the alarm. is your battery dead?
