The Theatre is a collaboration between theatre actor Avi Zlicha, who previously played in Haifa Theatre and throughout the years specialized in physical theatre by Jacques Lecoq`s method, and Dikla Katz, a playwright and puppeteer, who wrote for Arutz HaYeladim (the Israeli "Children Channel").

Combining film and theater has led to the creation of a company that employs different theatrical languages for each show.

Throughout the years, the Key Theatre has collaborated on projects with the Israeli Chamber Orchestra, the Renaissance Festival, Haifa Festival, the National Maritime Museum, the Tel-Aviv Museum of Art and many more.

In 2015 Dikla Katz was nominated as the official representative of UNIMA in Israel.

It has performed with "Baron Munchausen" in Vietnam and Kazakhstan (2012), and with "When all was Green" in Macedonia,[2] Senegal, South Korea,[3] Bulgaria (2014), Armenia,[4] Italy (EXPO),[5] Taiwan, Slovenia, Japan, Kosovo,[6][7] Norway,[8] Poland (2015), Belarus,[9] Slovakia, Thailand, Myanmar, India,[10] Montenegro, Croatia and Romania (2016).
