Which is not an easy task to unlock. There are different levels of Encryption access.

This is due because they may want certain features available to one group of people such as locksmiths who may need to add a new key to the vehicle while still keeping the other levels secure.

So a typically Security Access transaction will have sub-functions that will essentially be the level that you wish to access.

Really tricky stuff. There could be over 4 billion different combinations. And if this process is Dynamic even worst.

But with a team we can reverse which sub security seed and key algorithm to grant us access to the reprogramming section.

I have a Plan for this, But I will not discuss it openly until I've confirmed my speculations this weekend.

Anybody care to shed some light?

Thanks
