  We present a general model with universal extra dimensions in the presence of
the bulk fermion masses and boundary localized kinetic terms, which are
generically allowed by symmetries of five dimensional gauge theory. We provide
a comprehensive analysis for a general UED model, including Kaluza-Klein mass
spectra, their interactions with the SM particles, and constraints from LHC,
electroweak tests, and dark matter experiments. Finally we show current bounds
on the size of allowed universal bulk mass and universal brane-localized terms.
