Car Alarm Randomly Triggers

[RESOLVED]

Good Morning Everyone.

The initial conversation happened here:

But it didn't really relate to the OP's question so I thought I'd duplicate it here in this separate thread. Here are a few posts detailing the issue (resolution at the bottom of the post):

After ten minutes, the alarm actually activates as if someone were breaking into the car. It's happened six times in five days, the first occuring right after I got the car home from the initial purchase at around midnight. I felt like a total ass. The neighbors were probably like, "Damn dumbass...showing off and his new car..."

At any rate, I'll be contacting the dealer today or tomorrow.

This is how the service dept guy told me to diagnose it:
1. Start the car and then turn it off approximately 30 seconds later.
2. Exit the car and lock the doors with the key FOB.
3. Wait for the alarm to arm itself. He said to wait 1-2 minutes, but I had to go do something so I ended up waiting about fifteen minutes.
4. Tug firmly on the driver's side and passenger's side door handles. Also pull up on the trunk.
5. If the alarm sounds, then make a note of which opening caused it, and bring the info to your dealer to have that sensor adjusted/replaced.

I yanked on the passenger side and trunk and nothing happened. I barely touched the driver's door and the alarm sounded.

I'll update again after the visit this afternoon to let everyone know if the issue was resolved.

Just got the car back from the dealer and my issue has been resolved. Apparently the door/trunk sensor's have an adjustable sensitivity. The service lady stated that the driver's side door was set at it's highest sensitivity, which is 8. They turned it down to 2.

I tested the car several times yesterday and I don't have any more issues with the alarm randomly activating any more.

FIXED! YAY!

Is there a way to temporary disable the alarm? I was digging through my paperwork and manual but couldn't find anything on this. Taking this to the dealer next week but in the mean time it's driving me crazy.

I have a small red button right next to the trunk release. It could be alarm-related but I'm not really sure. I hate having buttons and not knowing what they do.
