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

The programming process makes the car learn the ID of the key, so there is not a permanent connection to the car. Each remote is unique, so the person who owned the car that it came from can not come and steal your car with his other remotes.
