Hi all, I recently picked up a 2006 IS350, however the seller only had one remote to the car. 
So I ordered two additional new Smart Card key to register to the car through the use of the "aftermarket" M-VCI cable. 

Please keep in mind, there is no way to program used keys/cards without additional expensive hardware/software. 
So these steps only work for brand new never been programmed cards/keys.

:: DISCLAIMER :: 
These instructions are provided as a reference for you to refer to adding additional remotes to the car. 
These procedures worked on my vehicle, however your miles may vary, therefore, I am, in no way, responsible for any damages caused in the process.
Please do not continue reading if you do not agree!


Stuffs you will need:
(1) - NEW, never programmed , Smart Card Key (parts # 89904-50641)
(1) - 32-bit Windows XP/7 laptop with Toyota Techstream installed
(1) - M-VCI USB to ODBII Cable with 32-bit drivers installed
(1) - Original programmed remote for the procedures

This is how a brand new, never programmed, found on eBay.


This is all the stuffs you need in order to program the key:


Location of the OBDII plug, it is right above the brake pedal with a black cover


Run Techstream, and click on "Connect to vehicle"


After initialising, this will show up, pick OTHER if you do not have radar cruise, then press next


Then double click on Smart Access


Then click on "Utility" on the left hand side


Then click on "Smart Code Registration"


Then check all the boxes and press next,


Then Techstream will inform you how many slots are available and taken,


Then Techstream will inform you to place both new and programmed remotes outside of the vehicle. Press next


When you are ready, press Pre-Start CHK to enable the Start box, and quickly tap the registered remote to the ignition botton in the vehicle with the L logo facing it.


Then quickly place the original remote outside of the vehicle and tap the smart card to the ignition button


Lastly, congratulations, you have successfully programmed the smart card to the system
