how to change the default table locking type ?

Hi guys,
Is there anyway to change the default recode locking type (Table
Locking) to row locking !! ?
Thanks in help

As far as I know SQL Server begins with a low type (row locking) and
increase if it needs.

AllowRowLocks, AllowPageLocks, DisAllowRowLocks, DisAllowPageLocks for each
index.
By default, SQL Server considers the locking granularity automatically, and
the default choices it makes are usually best.

determine that the
