So you have the remote for it and everything? Try leaving a door open as you put the groceries in. If it's like my alarm that'll do the trick. Also if it's like my alarm, you'll have a "valet" button hidden somewhere (mine isn't hidden, since really without having already disarmed the alarm or having the key for the car, it wouldn't do a thief any good). You can use this button to completely turn off the alarm (disarm alarm, then hold the button, you should get a confirmation of some sort). You can also use it to turn the alarm off if your remote doesn't work, put key into ignition then hit the button. That's only if it's like mine though, your's could be completely different. Also the valet button may never have been installed. If you wanna change the settings (another function of the button)/get the button added, you probably would want to go to an alarm shop.
