How Do You Unlock The Code For A Sony DVD Player?

All models of Sony DVD players are fitted with a code called a regional lockout code. A regional lockout code is a practice, code, chip or physical barrier. It is used to prevent the media originating from one country, which can be played only on a device from its country of origin, from being played on the corresponding version of the same device which is sold in another country. A regional lockout code is a form of vendor lock-in.

Sony has a regional lockout code for Universal Media Disc (UMD) movies. It is because of this that movie buffs in Japan and elsewhere have to pay almost thrice the price to watch a UMD version of a movie than their counterparts in the United States. It is legal in Japan to import movies. Restriction of imports is prohibited by law in Japan. However, the regional lockout code makes it difficult to play a disc that is originally from another region without using the appropriate additional technological measures.
