Hi i have a used key i got from Japan to program as normal with a Japanese Toyota Aqua (Prius C).
However when i try to program it never is successfully added to registered keys.
I switched batteries between the original and new fobs and tried Toyota TIS, X100 PROS, and IMMO function on Launch X431 and none are able to register the new key. I was even able to delete one of the original keys and the key count went down so i'm sure the software itself is working just not the registration process.

I'm thinking maybe there is special prep procedure for Aqua or something, but really not sure how to proceed.
Has anyone done this with the Aqua? Where am i going wrong is there any other tested and working way to do it?
