In 1983, Zabka graduated from El Camino Real Charter High School in Los Angeles before briefly attending California State University, Northridge and majoring in film.
Zabka's breakout acting role came in his first movie, The Karate Kid (1984). He played Johnny Lawrence, the main antagonist to the title character and protagonist played by Ralph Macchio. He had no training in karate at the time but was an accomplished wrestler. His participation in the film inspired him to learn the martial art of Tang Soo Do and he later earned a second degree green belt.
During the 1980s, Zabka appeared in the comedy movies Just One of the Guys (1985) and Back to School (1986). Zabka also co-starred on the CBS television series The Equalizer as the son of the title character (1986–89). He also played Jack, Audrey's jock boyfriend, in National Lampoon's European Vacation (1985). He later tried to step away from playing the class bully character. He mentioned in an interview how he was sometimes hassled in public by random people because of the villainous characters he was best known for.
During the 1990s and 2000s, he acted mostly in independent films while studying to be a filmmaker. In 2003, he wrote and produced the short film Most, shot on location in the Czech Republic and Poland.

In 2004, he was nominated for an Academy Award for Most in the Live Action Short Film category.
In 2007, Zabka directed and starred in a music video for the band No More Kings entitled "Sweep the Leg". The video stars Zabka as a caricature of himself, living in a trailer in the desert and obsessed with his role in The Karate Kid. The video includes cameos by several of the original Karate Kid cast members, including Martin Kove and Ralph Macchio. In 2010, Zabka directed Rascal Flatts in their music video for the song "Why Wait" and also directed the video for their 2017 hit "Yours If You Want It".

He also co-executive produces the series with Ralph Macchio. The series is set 34 years after the events of the first film, and revolves around a down and out Johnny who, seeking to rebuild his life, reopens the Cobra Kai dojo. It reignites his rivalry with a now-successful Daniel LaRusso (Macchio), who has been struggling to maintain balance in his life without the guidance of his now-deceased mentor, Mr. Miyagi.
