The active anti-theft is a wonderful system but is very tempermental. Mine kept going off because the tilt sensors sensed that my car was moving from side to side when i was on a ferry and the alarm kept going off!!! So i discovered by poping the trunk it de-activates the tilt sensors.
And if you don't want the system to go off, then there is one fool proof way to have it not go off. Click the Unlock on the fob and open the driver's exterior door handle like you normally would. The system re-activates itself after 30 seconds so be careful not to take too long.
