A Dalitz plot analysis of approximately 12 500 D{sup 0} events reconstructed in the hadronic decay D{sup 0}{yields}K{sup 0}K{sup +}K{sup -} is presented. This analysis is based on a data sample of 91.5 fb{sup -1} collected with the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} storage rings at SLAC running at center-of-mass energies on and 40 MeV below the {upsilon}(4S) resonance. The events are selected from e{sup +}e{sup -}{yields}cc annihilations using the decay D*{sup +}{yields}D{sup 0}{pi}{sup +}. The following ratio of branching fractions has been obtained: BR=({gamma}(D{sup 0}{yields}K{sup 0}K{sup +}K{sup -})/{gamma}(D{sup 0}{yields}K{sup 0}{pi}{sup +}{pi}{sup -}))=(15.8{+-}0.1(st= at.){+-}0.5(syst.))x10{sup -2}. Estimates of fractions and phases for resonant and nonresonant contributions to the Dalitz plot are also presented. The a{sub 0}(980){yields}KK projection has been extracted with little background. A search for CP asymmetries on the Dalitz plot has been performed.
