In this work, we examine the Kerr/CFT correspondence for magnetized black holes arising from Kaluza–Klein theory, demonstrating that Kerr/CFT holography persists beyond the traditional Einstein–Maxwell framework. Notably, unlike in the Einstein–Maxwell case, the massless neutral scalar field equation here is fully separable into radial and angular parts. This separability reveals a hidden conformal symmetry in the near-horizon, low-frequency regime, providing further support for the robustness of Kerr/CFT dualities in extended gravitational theories.
