Ollie Banks scored his fourth goal in three games and Armand Gnanduillet headed a second on the stroke of half time to boost Chesterfield's promotion challenge.
Tommy Lee marked his 200th League appearance for Chesterfield with a vital save to deny Billy Knott and celebrated a fourth consecutive clean sheet as Lynch reflected on a solid team display.
"We've worked on a few things in terms of getting Ollie (Banks) on the end of crosses into the box and it's so pleasing when they come off," he admitted.
"It was one of those games where we needed a goal to liven things up and the second was another we have been working on at the training ground.
"It was a great goal to score on half time and they changed the way they played in the second half and did well without troubling us too much and I think it was a professional job from the lads in the way we saw the game out which is what you need to do at this level.
"Tommy (Lee) is a true professional in the work rate he puts in on the training ground and how he conducts himself on the pitch and the way he marshals the defence.
"I'm so pleased for him, he's been honoured by being made captain on his 200th League game so to keep a clean sheet as well will be something he will treasure for a long time."
