Keane's second-half doubled enabled Aston Villa to triumph 3-2 as the on-loan Los Angeles Galaxy striker marked his full debut with two superb strikes in a thrilling Premier League encounter.
But even the boos directed towards him by some Wolves fans did not tempt Keane to show any disrespect towards the club where he started his career.
Keane said: "I had wonderful times at Wolves and they are a club that looked after me as a kid.
"I'll never forget, they did so much for me. I've got a lot of friends at the club still and it's always great to come back.
"I'll never celebrate if I score against them. I never celebrate when I score against any of my former clubs out of respect.
"But you have to be professional, do the job for the team that you are with, and that's Aston Villa.
"You have to put everything to one side and concentrate on your own job."
Keane looked sharp in his first start since the conclusion of the Major League Soccer campaign.
He said: "I feel good, I feel sharp, this was my first game since December 7.
"I've felt good the last few weeks in training. I'm feeling sharper and sharper and you saw that against Wolves.
"As a striker, I'm judged on goals. But the most important thing is the three points for the team and helping the team push up the league.
"I'm only here for a short time so if I can help in any way possible, then great."
Villa manager Alex McLeish said: "Somehow I had to get Robbie into the team. I said that to him last week.
"I said 'train well this week and I'm seriously thinking about you'. After what happened at Wolves, he picks himself.
"Robbie is a proud man and whoever he plays for, he'll do his best for that team.
"He has got a lot of affection for Wolves but right now he is a Villa player and he showed how passionate he is about the game and how much it meant to him with two cracking goals."
Wolves have now slipped into the bottom three for the first time this season and manager Mick McCarthy felt midfielder Karl Henry's straight red card was the turning point.
Former skipper Henry will now miss the games with Liverpool, QPR and West Brom through suspension after kicking out at Villa winger Marc Albrighton when the score was 2-2.
McCarthy said: "The sending-off has cost us the game. I have no complaints about the sending-off.
"Karl was fouled beforehand but that doesn't excuse him kicking out.
"It's downright daft and it cost us the game, certainly. It was stupid."
McCarthy is also waiting for a fitness update regarding on-loan Arsenal midfielder Emmanuel Frimpong, who went to hospital after suffering an eye injury.
He was accidentally kicked in the face by Villa skipper Stiliyan Petrov when attacking a corner from Michael Kightly at the start of the second half.
A Wolves spokesman said: "Emmanuel Frimpong will undergo a further assessment on the eye injury which saw him stretchered off against Aston Villa.
"He went straight to hospital for an initial assessment and an initial examination revealed no head or spinal problems.
"He has severe swelling around his eye and will need a further examination to discover the extent of the problem."
Darren Bent's early penalty put Villa ahead but Wolves dominated the remainder of the first half, with Michael Kightly and Dave Edwards on target, before Keane turned the tables after the break.
