Fits the ILCO Look Alike Key Shells TOY40B, TOY43, and TOY43R and the Electronic Modular Head GTHT128C.  Works with some keys for the Toyota vehicles that require the T128C transponder.

The Ilco Toyota® “H” Solution adds the capability to clone Toyota vehicles that use the Texas® AES128 Bit Encrypted transponder keys while also pre-coding Subaru keys for programming with a diagnostic device. No Snoop Required.
The Ilco Toyota® “H” Solution requires the use of the RW4 Plus or Ilco EZ®-Clone Plus and is a simple read/write process that requires a free software update (version 04.08.093 or higher) and the new T128C transponder. The Ilco Toyota® “H” Solution does not require the presence of the vehicle, use of a Snoop, the M-Box, or an internet connection.
The new T128C transponder will be used in conjunction with Ilco replacement vehicle keys for cloning all Toyota® “H” applications and for presetting keys for Subaru “H” applications. Once pre-set for Subaru “H” applications, the transponder must be programmed into the vehicle with a programming device like the Advance Diagnostics Smart Pro. The new GTHT128C modular head contains the T128C transponder and can be used in conjunction with the Ilco modular EB3 blade system. The T128C transponder does not replace the GTI, T48, or T80 Plus transponders. These transponders are still needed for their respective vehicle applications.
