Each installation generates a unique HWID based on your CPU serial, motherboard MAC, and hard drive volume ID. A keygen would need to reverse-engineer Bosch’s HWID-to-License algorithm—a 256-bit elliptic curve cryptography (ECC) scheme. No public crack has succeeded.

There are legal, open-source diagnostic tools that work on Toyotas:
