Pin code for DVD player

My son has put a pin code on his PS2, Doh! he forgot what he put
in. Is there anyway to reset the code.
Thankx in advance.

the universal code is in the manual, and how to replace the original code

im sorry, but we do not permit the posting of the parental code here, as a child might see it.

if you lost yer manual (dont we all?) go to google and do a search for it (the code, not the manual)
