What owners wrote

At approximately 11:30 pm, I heard a vehicle horn honking outside in the driveway. Got out of bed to investigate. Observed my 2102 ram 3500 diesel truck with lights on and flashing and horn was honking. Keys for truck were in the house. Went outside with keys and tried key-less entry fob to open the cab door with no success. Smelled smoke. Opened drivers side door with regular key to see lights on dashboard all lit up.
