Default I cannot program my new ebay key

I bought a new key from ebay, followed the online instruction.
Today I tried quite a few times, it won't add my new key to the ECU. Can someone point it out what did I do wrong?

1. Insert original Key 1 --> turn key to ON. --> remove key in 5 seconds
2. Insert original Key 2 --> turn key to On. --> remove key in 5 seconds
3. Insert ebay Key --> turn key to ON. --> ?? it doesn't register

You may need to take it to a dealer to have them program the key.
