The excitation function for the $pp\to ppK^+K^-$ reaction revealed asignificant enhancement close to threshold which may plausibly be assigned tothe influence of the $pK^-$ and $K^+K^-$ final state interactions. In animproved reanalysis of COSY-11 data for the $pp\to ppK^+K^-$ reaction at excessenergies of Q = 10 MeV and 28 MeV including the proton-K- interaction theenhancement is confirmed. Invariant mass distributions for the two- andthree-particle subsystems allow to test at low excess energies the ansatz andparameters for the description of the interaction in the ppK+K- system asderived from the COSY-ANKE data. Finally, based for the first time on the lowenergy K+K- invariant mass distributions and the generalized Dalitz plotanalysis, we estimate the scattering length for the K+K- interaction to be|Re(a_K^+K^-)| = 0.5 + 4.0 -0.5 fm and Im(a_K^+K^-) = 3.0 +- 3.0 fm.
