We consider a simple extension of the Standard Model (SM) with a vector-like lepton and a local symmetry, motivated by the recent experimental anomalies in the muon
and the W boson mass. The
symmetry is spontaneously broken by the VEVs of the dark Higgs scalar and the second Higgs doublet, giving rise to the mixing between the muon and the vector-like lepton. As a result, we obtain the desirable corrections to the muon
and the W boson mass simultaneously, dominantly due to the
gauge interactions for the vector-like lepton and the second Higgs doublet, respectively. We also discuss the consistency of the model with the Z boson decay width, the Higgs couplings and the dilepton bounds.
