unlock microcontroller

i would like to read the code from the locked microcontroller(89c51,89c52..) so pls help me, how do i achieve this....
basically how do i unlock them...

Well i think its Illegal...! as far as i know. you need a written concern from the manufacturer or something like that..
Just a hint.. you need to open the IC and and burn the locks.. [ i saw this on a site ]
