I'd love to see those instructions. They sound like instructions for the Classic.

The US repair manual hint at the possibility that you could do a re-program without the THHT, but even with the THHT, the instructions are confusing. There are three security functions that have to be placed in sync: SKS, remote lock, and the immobilizer. I think 2 of them program together.
Even dealers get into trouble, where they can program the immobilizer but can't get the SKS to program. However, now that other Toyota/Lexus vehicles are coming equipped with SKS, more dealer techs will be familiar with the process.
