Im guessing the remote could be dirty. Therefore it might be sticking.

The most common cause of that problem is the shock sensor. You can try turning down the sensitivity but most people find that they have to disconnect it to get the problem to go away. Then you can either leave it disconnected or replace it - P/N 10444928, about $43 at the dealer.

No, it is probably just a defective sensor. They tend to get moisture in them and over time they will get bad enough to cause the alarm to stop working properly.

I found that if I left any loose change in my ashtray, that would set off the motion sensor. I had to turn down my motion sensor almost all the way down.

I'm having a problem

Today I noticed a low rear tire so I ran up the street to add more air. Didn't fool with anything at all other than that I came right back home. I started fooling around the house with chores and managed to hear my alarm. Ran outside and sure enough the horn was blasting. Neighbors were out ao I knew no one had fooled with it. It had just began to rain (small shower). I disarmed and re-armed the car. Within 15 seconds or so it began again. Repeated the same procedure and damned if it didn't go off again. So I just locked the car from inside and it started going off after that. So as of now I just left in unlocked.

Info on the car: Bought the car about 3 months ago max. Done nothing to it as of yet. It has rained the laste few weeks, and right after buying the car. Never have I had this problem before. Can anyone chime in and help me?

Hey, new to the site just wanted to ask a related question bout this. When i turn my car off and lock the doors the alarm will set itself right after all the doors are shut but the horn blasts twice as loud as all h*** every time twice just wondering if this is normal or not. I know something is wrong cause it'll sometime blast the horn twice a couple hours later like its arming itself again sometimes. Anyone every have a prob like this?
