  The contributions for the kaon pair from the intermediate states
$\rho(1450)^+$ and $\rho(1700)^+$ in the decays $B^+ \to \bar{D}^0 K^+
\bar{K}^0$, $B^0 \to D^- K^+ \bar{K}^0$, and $B_s^0 \to D_s^-K^+ \bar{K}^0$ are
analyzed within the perturbative QCD factorization approach. The decay
amplitudes for all concerned decays in this work are dominated by the
factorizable Feynman diagrams with the emission of the kaon pair, and the
charged $\rho$ mesons should be of great importance in the $KK$ channel of the
related three-body $B$ decays. Moreover, these quasi-two-body decays are
CKM-favored, and the relevant branching ratios are predicted to be in the order
of $10^{-5}$, which have the potential to be measured by experiments. It is
also shown that the contributions of the subprocesses $\rho(1450, 1700)^+ \to
KK$ for the three-body $B$ meson decays are considerable according to the total
three-body branching fractions presented by Belle. Therefore, the decays $B^+
\to \bar{D}^0 K^+ \bar{K}^0$, $B^0 \to D^- K^+ \bar{K}^0$, and $B_s^0 \to
D_s^-K^+ \bar{K}^0$ can be employed to study the properties of $\rho(1450)$ and
$\rho(1700)$ in the LHCb and Belle-II experiments.
