The exclusive B -> K(2)l(+)l(-) decay is studied using the most general, model independent four-fermion interaction. The sensitivity of the ratio of the decay widths when K-2 meson is longitudinally and transversally polarized, the forward-backward asymmetry and longitudinal polarization of the final lepton on the new Wilson coefficients is studied. It is found that these quantities are very useful for establishing new physics beyond the standard model.
