Instructions
Place your Xbox on a level surface. Placing the Xbox at even a slight angle or on its side can cause the disc tray to malfunction and not open.
Connect your Xbox to a power source. The disc tray is electronically powered and can become stuck if you attempt to open it without providing electricity.
Press the "Eject" button on your Xbox. This is the large, round button located to the right of the disc tray. This will open the disc tray and allow you either to insert or remove a disc from the system.
