Lakin got her start acting in commercials, before landing her first major role as Young Rose in the American Civil War drama The Rose and the Jackal. That movie aired in 1990, one year before she was cast as Al Lambert, the tomboyish daughter, on Step by Step. After Step by Step was cancelled in 1998, she continued to appear in television movies, such as Showtime's Reefer Madness and 2005's Who's Your Daddy?. In 2006 she was a regular cast member in MTV's Wild 'n Out, an improv comedy show similar in structure to Whose Line Is It Anyway? She also appeared in a commercial called "But He Has Bud Light" that aired during Super Bowl XLI, in which her male companion wants to pick up a hitchhiker who has Bud Light beer in one hand and an axe in the other.
