Motivated by recent experimental results, we use a factorization approach to study the three-body B\ensuremath→D(*)K^\ensuremath-K0 decay modes. Two mechanisms are proposed for kaon pair production: current produced (from a vacuum) and transition (from the B meson). The B0\ensuremath→D(*)+K^\ensuremath-K0 decay is governed solely by the current-produced mechanism. As the kaon pair can be produced only by the vector current, the matrix element can be extracted from e+e^\ensuremath-\ensuremath→KK processes via isospin relations. The decay rates obtained this way are in good agreement with experiment. Both current-produced and transition processes contribute to B^\ensuremath-\ensuremath→D(*)0K^\ensuremath-K0 decays. By using QCD counting rules and the measured B^\ensuremath-\ensuremath→D(*)0K^\ensuremath-K0 decay rates, the measured decay spectra can be understood.
