Driver door lock cylinder replacement in 2002 Subaru Impreza Outback Sport

I had the door lock cylinders re keyed by a locksmith. I have reinstalled the driver door lock cylinder, tested the key in the cylinder before reinstalling the cylinder however seems after installing cylinder in door the key does not turn full 180 degrees. I can lock the door with key however cannot unlock. What did I not reconnect properly? I got everything to work on passenger door.
