05 Solar Prius

I've been able to enter the add mode successfully which was confirmed by the car's lock-unlock sequence once or twice depending on the procedure followed but, I didn't have any joy programming the new fob.


So finally the queries:

Has anyone programmed a 2 button and a 3 button black logo Fob on the same car simultaneously?

Can anyone confirm that the fob no. B21TA and B21TG are interchangeable?

Any other suggestions?

Has anyone other tha Jaquimo programmed a used black logo key from ebay which has probably been used more than the 128 times?

Any one from Australia who has successfully programmed a used key from USA? could you help me please? Thanks in anticipation.
