If you have the standard key cap that I posted above then most likely there's a transponder pill inside of it. It might not have been programmed.
If I recall correctly there are two versions. I'm not sure if the other one looks different. Perhaps you can answer that question if it's different by posting a picture.
The difference is one is with and the other is without the transponder. I also remember reading that you do not need the bar code to program it like the remote
. I never tried this though.
I guess for the sake of it we can call both versions valet keys.
