Mine did this it has to do with the doors not locking correctly.. Spray wd40 in all lock mechanisms including liftgate. Open and shut a few times and you should be good

Try resetting the alarm, using the instructions given at the link below. I'll also copy the text here.

  1. Insert the ignition/door key in the door lock on the driver's- side door of your Mountaineer.
  2. Turn the key to the lock position.
  3. Turn your key to the unlock position.
  4. Turn your key to the lock position.
  5. Turn your key to the unlock position. Your alarm is now disabled. If your key fob works, you can also press the unlock or alarm-disable button on the fob.
  6. Start the Mountaineer's engine and allow the vehicle to run for at least 10 minutes. This will allow the alarm to relearn the default settings. You must make sure that you have disabled the alarm first, however, before you attempt to start the vehicle, so that the alarm will reset itself.

If these instructions don't work, you can try resetting the car's computer by unplugging the battery for half an hour. However, that will reset the keyless entry code, as you can see in the fixya article I link to at the bottom

My car alarm goes off intermittently
Assuming that you have the dealer installed PRESTIGE alarm unit,I would recommend decreasing the sensitivity of the motion sensor, or replacing the alarm control unit. This black plastic piece, located somewhere in the left kicker panel not only handles the sound/motion alarm, but the flashing alarm, the keyless power locks and the theft code for the radio. It is rare that these boxes fail, more than likely a rusty sensor at the doors, trunk or hood will be the culprit. Mine goes off when cats go under the car, and cant figure why. I am making a decision on fixing the alarm, or fixing the cats.

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.

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.
