Please help me by going over the following information to see if there is anything that I have not taken in to consideration before I proceed to manually edit the data in my 2002 (Canada-California) Toyota Sienna's immobilizer (Fairchilds 93C56 eeprom) in a Denso (89661-08070) ECU.

The YouTube video in this link: is of a guy changing the data manually and I captured a before and after screenshot of the eeprom data and I also have gotten data from someone in the following forum post:

YouTube Hack & My Data HALF.jpgYouTube & Toyotoa Nation Virginizing Done.jpg

According to those pix if I zero all data except the valet lockouts my immobilizer will be virginized, Is this correct or do anyone see a problem with this idea? Please help
