"Key to My Life" is the third single from Irish boy band Boyzone, taken from their debut album, Said and Done (1995).

It was released in April 1995 by Polydor Records, and after two covers, it became their first single to be an original song, co-written by members of the group.

The accompanying music video features the band performing in a classroom at a school.
