BARNSLEY took one step closer to the play-off places after they thrashed Luton Town 5-0 at Oakwell on Saturday afternoon.
Reyes Cleary gave the Reds the lead before Patrick Kelly made it 2-0 on 35 minutes.
Luca Connell then scored a sublime free-kick on the stroke of half-time.
Tennai Watson bundled home from close range in the second half to make it four before Keillor-Dunn made it 5-0.
Conor Hourihane made two changes to the side that beat Doncaster Rovers earlier this month.
Josh Earl returned to the starting 11 following injury and replaced Jake Rooney at left-back, while Davis Keillor-Dunn recovered from illness to take the place of David McGoldrick who dropped to the bench.
Ex-Red Mads Andersen started the game for the hatters while Jacob Brown was on the bench.
Vimal Yoganathan came close for the Reds in the opening the minutes but his effort from the edge of the area rattled the crossbar before going out of play.
He had combined well with DKD in the middle of the pitch before dribbling into the box but he couldn't quite give the Reds the opener.
But Barnsley did take the lead just five minutes later as Reyes Cleary beat the offside trap and cheekily chipped the ball over the Luton 'keeper.
It was DKD again who was the playmaker, and the Reds took a deserved lead.
Josh Earl almost gifted the away side an equaliser ten minutes later as his header is too weak and Nakhi Wells looked certain to score.
He took it round Murphy Cooper but Marc Roberts did fantastically well to clear the ball off the line.
DKD should've doubled Barnsley's advantage on the half-hour mark after he and Cleary switched roles and it was the winger who played through the striker.
But his first-time strike was just wide of the post.
Yoganathan rattled the woodwork for the second time in the first half on 31 minutes.
This time Keeley completely missed the ball and the young midfielder shot from a tight angle but could only hit the post.
But the Reds did double their lead just three minutes later as Patrick Kelly tapped home from close range after Reyes Cleary did well to play the ball across the goal-line.
Luca Connell made it 3-0 on the stroke of half-time, as he scored a sublime free-kick to send the Barnsley fans wild.
Luton started the second half well but it was Barnsley who came the closest in the opening minutes after Roberts' header from a Connell corner went narrowly over the bar.
Cleary then came close after combining with Yoganathan but his curling effort was inches wide of the post.
Tennai Watson made it 4-0 in the 63rd minute.
Connell found Cleary from a free-kick, he beat his man and then played it to Yoganathan whose effort was well-saved before Watson fired home for his first Barnsley goal.
Keillor-Dunn scored the fifth in the 75th minute, wrong-footing Keeley to start an exodus in the away end.
The result meant Barnsley leap-frogged Luton in the table.
