A system and method for sterilizing a surface on an input device is disclosed. A chamber is configured to enclose an input device such as a keyboard and is configured to be switched between an open and a closed state. A drive unit may be provided to switch the chamber between states. In an embodiment, the drive unit may include a motor. A sensor provides a signal to a controller when the chamber is the closed state and the controller actuates a UV light.
