Things You'll Need
Instructions
Turn on the PlayStation 2 and remove any disk that may already be in the device. Then insert a DVD, preferably one that will prompt you for the parental control code. Insert the code and allow the DVD to begin playing.
Press the "Select" button once the movie has started. This will bring up a menu. Find the "Settings" icon, and press "X" to enter the "Settings Menu." Scroll down and select the "Parental Controls Menu" and press "X."
Reset the "DVD Parental Control Level" to "Off," which will allow any DVD to play without prompting the user for the passcode. You may also choose to set it to level 8, which is the least stringent level.
Do not exit the menu after inputting the new settings. Instead, eject the DVD and remove it. This should cause the PlayStation to reset with the new settings enabled. If it does not automatically reset, then manually reset it by either flipping the switch in the back, or by holding the reset button in the front down. Leave the device off for a few seconds.
Turn the PlayStation back on and input a DVD that previously required the passcode. The PlayStation should now play the DVD without prompting you for the passcode. If it does, then you're finished. If it still prompts you for the passcode, then start again at step one and try it again.
