Do you have an owners manual, there is a very good section on all this. I haven't read it in about a month but I was surprised with the cool features. Pushing the remote lock twice is different then pushing it once. If I remember this correctly and I actually sat in my car and tried it, if you push it once you get two blinks...move in the car an bang the alarm goes off, if you push it twice is will only go off if you open the door, this is so you can leave someone in the car when you go in a store and they can move around, but if someone tries to open the door it will set off the alarm. I don't remember if the alarm siren is suppose to sound in that case. Also if I remember correctly this all behaves differently if the top is down...of course having motion sensing with the top down would make no sense. It is surprising how many little things the car does, guess when someone was paying 53k back in 2000 for one of these they expect this stuff, not that they ever probably used it.
Give the manual a read, take it to the car with you and go through each option.
