  We compute the logarithmic corrections to black hole (BH) entropy product of
${\cal H}^{\pm}$ \footnote{ ${\cal H}^{+}$ and ${\cal H}^{-}$ denote outer
(event) horizon and inner (Cauchy) horizons} by using \emph{Cardy
prescription}. We particularly apply this formula for \emph{BTZ BH}. We
speculate that the logarithmic corrections to entropy product of ${\cal
H}^{\pm}$ when computed \emph{via Cardy formula} the product should be neither
\emph{mass-independent (universal)} nor be \emph{quantized}.
