His first four films were pulled voluntarily from circulation by Cobra Video through their distributor, Pacific Sun Entertainment. In September 2005, Lockhart publicly stated he was 17 when he made his first films, thus was under the legal age of consent in 11 states, including California. He has also made films with Active Duty and Jet Set Men. He played roles in gay porn films, notably with Cobra Video and Pink Bird Media. Lockhart started his career in pornography in 2004, aged 17, using the stage names Brent Corrigan and Fox Ryder in Every Poolboy's Dream. Lockhart was under 18 when their relationship began, and it ended before his 18th birthday. A sexual relationship developed between Lockhart and Kocis.
Lockhart agreed to perform in filmed sex scenes with Kocis in six "action video scenes" and one "non-action" video scene in consideration for a used Volkswagen Jetta. The boyfriend controlled the camera while the owner of Cobra Video, Bryan Kocis, observed. This boyfriend introduced Lockhart, then 17, to the gay pornographic industry and arranged for Lockhart to audition for a pornographic film from Lockhart's own bedroom via webcam. His first boyfriend introduced him to a "fast, furious, out-of-control side to the gay scene", with which he was not comfortable. His mother and stepfather divorced when he was aged 8 to 9 years, after which the household broke down. He and his siblings were raised in the suburb of Mill Creek, near Seattle, Washington, with their stepfather. He is one of four siblings he has an older brother and a younger brother and sister.
