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 $B_s^0 \to D_s^-K^+ \bar{K}^0$ areanalyzed within the perturbative QCD factorization approach. The decayamplitudes for all concerned decays in this work are dominated by thefactorizable Feynman diagrams with the emission of the kaon pair, and thecharged $\rho$ mesons should be of great importance in the $KK$ channel of therelated three-body $B$ decays. Moreover, these quasi-two-body decays areCKM-favored, and the relevant branching ratios are predicted to be in the orderof $10^{-5}$, which have the potential to be measured by experiments. It isalso shown that the contributions of the subprocesses $\rho(1450, 1700)^+ \toKK$ for the three-body $B$ meson decays are considerable according to the totalthree-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 $B_s^0 \toD_s^-K^+ \bar{K}^0$ can be employed to study the properties of $\rho(1450)$ and$\rho(1700)$ in the LHCb and Belle-II experiments.
