I have never heard the 4C and 4D terms, but looking at some of the sites that sell blanks, the Yaris is listed as using 4D.

CTScott,

I think the 4D is a ref to the non fob key as I have seen them lised as model "4D67"

Last thing I still am not sure about is can I buy a used keyfob and program it even with the tool or at the dealership? Or are they "imprinted" permanelty to the car it came from?

I plan on taking out the guts of it and putting it in a flipkey body so the cut key on the old keyfob is not an issue as I will have to cut the flipkey anyways. Just concerend that a USED keyfob will somehow be already "locked" to the previous car
