To remove the key lock from your Grundig TV model GU26DVD without a remote control, you can try the following steps:
Turn on the TV using the power button on the TV itself.
Press and hold the MENU button on the TV for several seconds until the menu appears.
Use the volume up/down buttons to navigate to the "Lock" or "Child Lock" option and press the MENU button to select it.
Enter the four-digit password using the number buttons on the TV. If you don't know the password, you may be able to find it in the TV manual or by contacting the manufacturer.
Navigate to the "Off" option and press the MENU button to select it.
Press the MENU button to exit the menu.
If the above steps don't work or you don't have the manual to find the password, you may need to contact the manufacturer or a professional technician for assistance.
may have to purchase service manual, but if you do attempt this Understand that if you're not sure what you are attempting you can cause the unit to not work at all.
You can make this player REGION FREE so all discs operate on it.
Power up, no disk in. Status says READ then INSERT DISC.
Press MENU (status reads invalid key icon)

Press 9 Menu is displayed.
Press ENTER on the region, digit turns to "-"
Press 0
Press ENTER again
Press EJECT to clear the special menu.
If you reset (unplug) the player for any reason - this will need to be re-entered.
Did you make the disk if you made the disk your computer has to give it a digital signature so the DVD player can read it if you're using a regular DVD then I would very carefully using rubbing alcohol and Q tip clean the actual laser I would be very careful doing this if too much rubbing alcohol is on the Q tip it will ruin the laser you can also try resetting the DVD player by taking out the battery and unplugging it from any power source and leave it that way for at least 20 seconds to a minute if that doesn't work you might have something else wrong
