How do you unlock your Sony dav-dz 230 DVD player without remote control?

To do it with a OFA Kameleon 4:-

The DVD needs to be put in service mode. Start DVD and wait for disk to load. Press Stop followed by Eject, then turn the volume nob until the Service menu appears. Then, follow the same procedure as for most modern Sony DVD players:

1. Hold the magic button until it flashes twice.

2. Press DVD

3. Press 0533 (flashes twice)

4. Hold the magic button until it flashes twice.

5. Press 994

6. Press Magic Key (don't hold)

7. Press 00189

8. Press 1 ( this sets it to key 1 - it flashes twice )

Now program function codes into buttons 2-5 like this:

* Repeat steps 4-6, then 00255 2

* Repeat steps 4-6, then 00095 3

* Repeat steps 4-6, then 00221 4

* Repeat steps 4-6, then 00079 5

To actually convert the DAV-DZ111 DVD to region-free:

13. Press 12345 - Recorder goes back to standby

14. Press 12345 - Recorder starts up

Notes:

1 - Unlike the instructions for other Sony DVDs found here and elsewhere, the device should be powered up -- the hack procedure will not work with the DVD in stand-by

2 - Player does not display "SUCCESS" or "TIMER OK", it simply powers down then powers up
