My gv450 video player displays 'locked' on power-up. I have no remote control for this. How can I unlock it? please

Prior Fixya answer by Korede Atunrase:
Turn on your DVD player and television. Select the appropriate input source for your DVD player on your television.

Press the "Setup" button on your DVD player's remote control to display the main menu.

Navigate to the "Rating" menu option using the "Down" button on your remote control. Choose the "Parental Control" item by pressing the "Right" arrow button, followed by "Enter."

Enter the parental control access password using the numerical pad on your remote control, followed by the "Enter" button. If you did not previously setup a unique password, enter "8888" when prompted for the password.

Press the "Enter" button to display the parental control rating menu. Select the "8: Adult" menu selection by pressing the "Up" or "Down" directional buttons on your remote control, followed by "Enter." Press the "Open/Close" button on the front of the DVD player to complete the process.

I bought mine tonight. The above procedure works perfectly. It is now set to 0, and I confirmed via firmware version page.
Cheers!

Power ON with NO disc inside:
Press PAUSE on the remote-control
Press 3,1,4,1,5,9 in sequence using the remote-control
Press 0 on the remote to select Region Free
Press PAUSE again to save
Power OFF then Power ON.
Done.

Basically, the child lock feature is a security feature to keep the children away from unauthorized video content.
Your best bet is to get an original replacement remote.

You may try this general step to unlock without the Remote. However, it may not work for all the models.
Please hold down the Power button on the Player until "CHILD LOCK" or the "Key symbol" disappears from the front panel display. The Player will be unlocked.

If you had set a code number - the override code should be able to resolve the issue. Please follow the below steps to enter the override code.
1. Press SYSTEM MENU to display the Setup menu.
2. Use the Number buttons to enter the 6-digit number
"210499". The previous password will be cleared.

Hope this helps you in resolving the issue.

Thank You,
