My drive'rs side door on my Isuzu Rodeo 2002 won't open from the outside. Is this an expensive fix?

On most cars there are small plastic clips that keep the bars inside the door attached. These clips can jump off if someone uses a slim jim or coat hangar on the door, or possibly just fatigue over time. Not a costly fix, the clips are anywhere between a few cents to maybe four or five bucks, its the labor that will be expensive. Shouldn't take someone who knows what they are doing more than an hour. A semi-experienced person close to two hours.
