Your Blu-ray disc player has a security lock feature to help prevent children and others from opening the device. When you're ready to use it, being able to unlock it quickly adds more time to your musical entertainment. Not only that, but after a while, you may not need to lock the player at all. For example, such as when children are no longer near it or if you ever decide to sell it and replace it with a newer one. In any situation, unlocking your Blu-ray player is an important process to know.
Turn on the player.
Hold down the "Play" button for 15 seconds.
Release the "Play" button when "Unlock" appears on the display.
