    Ok so yesterday I had to leave my truck behind because it wouldn't stay on let me explain. I had an aftermarket alarm and remote start put on my 09 sierra 5.3 and worked fine for 6 months now when I went to turn the truck on it started then after about 3 seconds cut off. I also noticed the security light stays on solid when the key is in the ignition. Not to mention after a couple of tres to start the truck with my key, it quit working(the key) but the remote start would start the truck for a couple of seconds. Any ideas? Remove the alarm?

    First suggestion would be to remove the aftermarket alarm, hopefully that solves the issue.
    If your wanting remote start your probably better off adding the factory system, it's not as expensive as you might think if you source the parts on line and have the dealer do only the programing.

    That's exactly what I'm going to do this morning I'm just frustrated with the aftermarket alarm I'm going back with the factory.
