Instructions should be in the player's owner's manual
4357 is the master key to unlock parental control.
This is going to depend on what your parents set it with. Talk to them, and see if they will let you unlock it.
you either have to have the code.. or you can unplug it and plug it back in
Contact the equipment manufacturer or your parents for more information.
If you mean 'unlock' as in play discs from different regions, there is no region unlock for this model. If by 'unlock', you mean reset the parental control password, all Sony DVD's can be reset by entering 199703 when there is no disc in the player.
You put in the code you entered when you locked it in the first place. We're assuming that you're the parent and that you put in the code and therefore know it. If that's not the case, then you don't unlock it, kid.
First finish story with ginga and u can unlock 2 more players and play with 2 unlocked players then u can unlock all players by above process
Unlock, as in play DVD's from other regions, or unlock as in remove the parental lock for adult movies?
same question above
i reallly need to now the freakin answer
To unlock secret players on Nbk 2k9 simply enter in the code "2ksports". To unlock the China team type in: "2kchina".
When asked for your parental control password (with the disc out of the player), enter 199703. You will then be asked to enter a new password. Don't forget this one!
