Duplicating key fob

There is no such concept in the Gen 2.

As we've tried to tell you in the many multiple posts on this subject you have posted, you need a new (as in never added to any car) silver-backed logo key fob and an existing fully functioning fob. If you have these prerequisites, you can perform the "Chicken Dance" routine to add a second key.

If you don't have a fully functioning fob, you need a person with "credentials (like a Toyota dealer or accredited auto locksmith) to add a new key using the "all keys lost" routine. This involves getting a reseed code so the new key can be added.

 

It is highly likely you're getting something wrong. Most likely going too slow or too fast.

The timing of the various steps can be critical. Pre-read the procedure and highlight any steps where it gives the timing then make sure you do the steps within the required timing.

You don't need to worry about the "reseeding" procedure as you have a working key. The reseeding procedure is for when you have lost all keys and you need to delete all existing keys and add a new one.

 

Turn off the SKS system (under dash button is clicked IN) then see if your good fob works in the dash slot.

I have never tried the chicken dance so I don't know if missing a step will mess up programming the immobilizer (dash slot).

Might need a Prius capable scantool to see what's going on (maybe too many keys in the immobilizer ecu?)
