  We present preliminary results for the measurement of the branching fraction
of the decay B+- -> chi_c0 K+- from a sample of 75 million BB pairs collected
by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. The
chi_c0 meson is reconstructed through its two-body decays to pi+ pi- and K+ K-.
We measure BR(B+- -> chi_c0 K+-) * BR(chi_c0 -> pi+ pi-) = (1.08 +- 0.35 (stat)
+- 0.10 (syst))*10^-6 and BR(B+- -> chi_c0 K+-) * BR(chi_c0 -> K+ K-) = (1.48
+- 0.44 (stat) +- 0.17 (syst)) * 10^-6. Using the known values for the chi_c0
decays branching fractions, we combined these results to obtain BR(B+- ->
chi_c0 K+-) = (2.4 +- 0.7) * 10^-4.
