Service codes, also known as region codes, lock your DVD player to a specific part of the world. For example, a DVD player from Europe may not play DVDs from the United States. It will not recognize the disc you put in. You need to unlock the service code to allow your DVD player to recognize DVDs. Unlocking the code makes your player universal, allowing it to play DVDs from all over the world.

4. Follow the instructions to unlock your DVD player. Usually, it requires inputting the code with your player's remote control.
