HiCustomer Thank you for asking your question on JustAnswer.
I am assuming this blue-ray player was purchased in North America? If so even if you could unlock it, it would not play a movie from Italy since this player only plays NTSC video formats and a movie from Italy would be in PAL format. So unlocking the region code would not help you.
Thank you again for trusting us with your problem. Please reply as soon as possible so that we can finish answering your question.
You could try this. It's not really for this model though.
1. Plug LG DVD player (no disc in tray) in and turn on with REMOTE. 2. Wait for "NO DISC" message. 3. Press the open button on the remote. 4. Press the following sequence(using the REMOTE only) PAUSE, 3, 1,4, 1,5, 9 5. Wait for "CODE__" to appear. Enter 0 (all regions) then press PAUSE then press POWER. The unit should turn off leaving it region free, but be warned that it have trouble with Region 0 discs. If so just redo the above steps and at "CODE __" enter your region.
