Stuck in Dickinson, nd

True story, bought an old car off my cousin for my youngest kid to learn to drive on.
He gave me one key to it, first thing I did was get another key made.
The next time I seen him he dropped about a dozen keys in the glove-box of my truck, is said WTF?
He said they were keys to the car I bought, his wife had a bad habit of loosing keys, and then finding them.
