  We have a new observation that near horizon symmetry generators,
corresponding to diffeomorphisms which leave the horizon structure invariant,
satisfy noncommutative Heisenberg algebra. The results are valid for any null
surfaces (which has Rindler structure in the near null surface limit) and in
any spacetime dimensions. Using Sugawara construction technique the central
charge is identified. It is shown that the horizon entropy is consistent with
the standard form of Cardy formula. Therefore we feel that the noncommutative
algebra might leads to quantum mechanics of horizon and also can probe into the
microscopic description of entropy.
