I cant unlock my ps2 console to watch a region 1 dvd and ive tried some unlocks but they wont work

The best solution to the region code issue would be to create a region free copy of your DVD discs. You can play a region free DVD on any DVD player you like. Try Leawo Blu-ray Copy. It's one of the best Blu-ray/DVD copying program. You can use this program to create region free copies of your Blu-ray/DVD discs to play on your PS2. The post that follows will show you how to use it to create region free copies of a Blu-ray/DVD disc: How to Make 1 1 Disc to Disc Blu ray Backup with 1 Click Blu ray Copy...

Make sure your console has the ability to read region 1 discs in the first place.
REGION 1 -- USA, Canada
REGION 2 -- Japan, Europe, South Africa, Middle East, Greenland
REGION 3 -- S.Korea, Taiwan, Hong Kong, Parts of South East Asia
REGION 4 -- Australia, New Zealand, Latin America (including Mexico)
REGION 5 -- Eastern Europe, Russia, India, Africa
REGION 6 -- China
REGION 7 -- Reserved for Unspecified Special Use
REGION 8 -- Reserved for Cruise Ships, Airlines, etc...
REGION 0 or REGION ALL -- Discs are uncoded and can be played Worldwide, however, PAL discs must be played in a PAL-compatible unit and NTSC discs must be played in an NTSC-compatible unit.
The end result is that DVDs encoded for regions other than Region 1 cannot be played on a region 1 DVD player, also, players marketed for other regions cannot play region 1-stamped DVDs.

If you forgot the parental control code and you need to unlock that, though, then try this:
1.Bring up a screen where the unit asks you to enter in the parental code. You can either insert a restricted disc, or enter the DVD setup menu and go to "parental control" under
custom setup.

2.When the screen asks for the code, press the SELECT button, then enter in the code "7444".

3.The level adjustment under Parental Control dictates the strictness of the player. The lower the value, the more strict it will be. Either increase the value to lower the restriction, or disable the lock entirely by setting it to "off".

4.Once you have made your adjustments, be sure that the DVD tray is empty, and press the RESET button on the front of the Playstation 2. It is imperative the tray is clear of any DVD or game for the unit to save your settings.
