It could be the shock sensor; usually located around the steering column under the dash. It is a small black box with two small lights ( one red, one green) and a philips screw used to adjust the sensitivity. Counter clockwise reduces the sensitivity.
It could be an open trigger: door, trunk, or hood pin. If you have a pin in the trunk or under the hood that was added by the installer, they sometimes can be inadvertently bent downward by loading the trunk or, some guy changing your oil. If that is the case, just bend them back upwards until they make contact with the hood/trunk lid when closed and you receive one chirp when arming the system.
Here is a quick way to determine what exactly is causing the alarm to trigger: After the alarm triggers, disarm the alarm and pay close attention to the LED light. One flash is the shock sensor. Two flashes is the hood/trunk pin. Three flashes is the door trigger.
