Karanvir stated his acting at a very young age, playing the young Sanjay Dutt in his father's film 'Teja'. He also did several commercials and acted in TV serials like 'Just Mohabbat', 'Shararat' and the immensely popular 'Kasauti Zindagi Kay' (playing Prem). He also produced the play 'Plain Crazy About Love' starring Helen and wife Teejay Sidhu. He showed off his dancing skills on the reality dance show 'Kabhi Kabhi Pyaar, Kabhi Kabhi Yaar' with wife Teejay. They were runner-ups on the show. Then came 'Nach Baliye 4' where Karanvir immediately became Farah Khan's favorite. But the couple had to quit the show when Karanvir injured his knee.
