  We discuss prospects of the $Z'$ search at the LHC in non-minimal Universal
Extra Dimensions with tree-level brane-local terms in five dimensions. In this
scenario, we find two major differences from the usual $Z'$ physics: (i) two
$Z'$ candidates close-by in mass exist; (ii) the effective couplings to the SM
fermions could be very large due to drastic overlapping of their profiles along
the extra dimension. To evaluate the actual situation precisely, we reconsider
the important issues of resonant processes, i.e., treatment of resonant
propagators and including interference effects.
