So yesterday I went to turn my truck on and as I turned the key, nothing happened. At all. Actually, for about half a second the cluster lights came on, but they quickly turn off. Later on, as I was coming home in a different car, i noticed my hazards were on. This seems to be the alarm system going off (which is disconnected I'm assuming since I didn't hear anything). Could this be it, and how do I get my truck to run again? Some other vehicles can fix this by locking the door with the key, but I only have the ignition key which doesn't lock the doors (new buy). Thoughts?
