We generalize the entropy function formalism to five-dimensional andfour-dimensional non-extremal black holes in string theory. In the near horizonlimit, these black holes have BTZ metric as part of the spacetime geometry. Itis shown that the entropy function formalism also works very well for thesenon-extremal black holes and it can reproduce the Bekenstein-Hawking entropy ofthese black holes in ten dimensions and lower dimensions.Comment: 19 pages, no figure, JHEP3 style, to appear in JHE
