2002 Mustang GT factory alarm keeps going off

Ok so basically my issue is that my alarm isn't working right. Normally it takes two clicks to set the alarm, but lately one click and the car beeps twice and sets the alarm. Every once in a while the alarm will randomly go off. I have tried replacing the battery in the key fob. I've also tried using my buddies car battery but the problem still persisted. Any possible solutions would be greatly appreciated!

Mine was doing the same thing one day. Turned out one of the map lights on the rearview mirror had been left on.

The above suggestion is probably in the right direction. Make sure the door switches are working properly, no interior lights or trunk light are on.
