Security System Issue

[rkc613]

Hello,

 

My name is Rich and I just bought a 2009 Sierra Denali on Monday. The problem I am having is when I lock the door with the RKE my alarm will go off about 5 min later. It did it Wednesday night and tonight (Thursday). I dont hear it do it at work or when I go out. I cant figure out why it is going off out back. We have a foot of snow in Cheyenne and there are no footprints in the snow

 

 

 

Thanks,

 

Rich

It has done it two more times. I called the dealership and they said they would look at it. Only problem is I can not get off work until Nov 11th. I will let you guys know what I find out.
