I bought the truck a few months ago. He only gave me one key. The key works in the ignition cylinder and the drivers door lock cylinder. Can I buy a pair of door lock cylinders with new keys and re-pin the ignition cylinder to work with the new keys?

You can, but if you mess up it's a job!
They sell the matched sets with door cylinders too

Is it easier to re-pin the bad door lock cylinder to work with my current key?
