It can be any of the car door not got properly locked or the door is locked but the switch is not sensing the door locked.Open and close each door again properly.
Or else its problem with any of switch wiring getting in contact with alarm wiring causing it to happen.And last thing alarm connections needs to be inspected.Its getting short somewhere in between.

Horn just goes off for no reason

If you have a vehicle alarm installed the alarm module is faulty or set too sensitive. If you don't have any alarm installed there are a number of reasons for this to happen but in the end they all lead back to the ECM unit.

Alarm goes off for no reason. Message center shows hood is "ajar

Hi There isn`t much that can be done here, I would suggest you take the car to the dealership if the alarm is original, if it is after market then take it to any alarm shop, it needs to be reconfigured.
Good luck.

Car alarm goes off for no reason

There is probably a reason...I would look for bad grounds. A good place to look is at the battery terminal. Clean them and if the problem still exist, I would have an experienced tech look at the unit itself.

97 bmw 528i factory alarm goes off for no reason

disable the hood microswitch. just unplug it. That and the cabin sensor are the most probably reasons the alarm will go off.
Alarms are useless. Totally effin useless. So it goes off.....then whaddya going to do. Shoot someone? Call the police? or listen to it drain the battery over and over again.
But....you can't disable the alarm totally. The bmw engineers have tied it into the main computer. you can however disable the sensors one by one so it doesn't set off the alarm. Hood sensor....Hood sensor....that's the culprit.

Alarm goes off for no reason. 97 Jeep grand Cherokee.

There is a security system built-in to the Jeep Grand Cherokee during these years. The reason the alarm goes off is because of a change in the electrical system (like shutting a door) that triggers the alarm. To stop the alarm, either disarm with the remote or unlock the door from the outside with the key. This will shutoff the alarm.
