  In this work, we adopt the one-boson-exchange model to study the $Y_cK^{(*)}
(Y_c=\Lambda_c, \Sigma_c)$ interactions. After considering both of the $S-D$
wave mixing effects and the coupled channel effects, we can predict several
possible open-charm molecular pentaquarks, i.e., the single $\Sigma_cK^*$
molecular states with $I(J^P)=1/2(1/2^-)$, $1/2(3/2^-)$ and $3/2(1/2^-)$, the
coupled $\Lambda_cK^*/\Sigma_cK^*$ molecular states with $1/2(1/2^-)$ and
$1/2(3/2^-)$, and the coupled $\Sigma_cK/\Lambda_cK^*/\Sigma_cK^*$ molecular
state with $1/2(1/2^-)$. Meanwhile, we extend our study to the
$Y_c\bar{K}^{(*)}$ interactions, our results suggest the $\Sigma_c\bar{K}$
system with $I(J^P)=1/2(1/2^-)$, the $\Sigma_c\bar{K}^*$ systems with
$1/2(1/2^-)$, $1/2(3/2^-)$, and $3/2(3/2^-)$, the coupled
$\Lambda_c\bar{K}^*/\Sigma_c\bar K^*$ system with $1/2(1/2^-)$, and the
$\Sigma_c\bar{K}/\Lambda_c\bar{K}^*/\Sigma_c\bar K^*$ system with $1/2(1/2^-)$
can be the prime molecular candidates.
