How do I get an immobilizer passcode? (1 Viewer)

[Mauser]

I have 3 lexus vehicles that I bought with only a valet key. For the two older ones I was able to virginize the ecu and make my valet keys into masters and add keys with Techstream.

On my wife's 2005 GX470 there is a option on Techstream to reset the ecu, but it requires a passcode. This passcode is calculated from a seed number from the ecu of the vehicle. Does any body have a way to get a passcode?

I have found a site that will calculate the passcode, but they want you to pay for 5 codes and I only need one. I'll use this if I cant get it from somewhere else.

Thanks in advance for the help.

I ended up using the passcode calculator I found online. It worked great.

Now I just need to find 4 more vehicles to use the rest of the tokens on.
