I have a dead GMC Envoy?
Hauled GMC Envoy on trailer. ran the day before. Went to move it off the trailer and the battery was dead. couldn't get it fired up so we put it in neutral while the key was in accessory position and moved it down hill. put the car in park, put it on the battery charger. Came back later to turn it on and the car has no power and the keys are now stuck in the ignition as if the car is still in gear. Any suggestions?
