Lost my vin tag

My son put the keys to our dart down when we brought it home years ago. Looked for them for a month. Tore the car apart, sent him into the trunk though the back seat, tore the garage apart, house, etc. Finally found them, sitting on the back of the "little uns" batter powered car, 6 feet from the Dart.... oof... it didn't just walk away, it will turn up.
