Purchase a new smart key fob, need help!

Hello, I purchase a smartkey key fob with silver logo on back. The place I purchase it from said it was new & never program. When I received it I try to program it but can't get the door locks to function & the smart key options don't work, it only works when I insert it on the dash only. I read that when it is a used smart key it wouldn't be able to get the smart key options since its been program to another vehical so thats why I purchase a new one.
Could it be that he sold me one thats been program before or is it something that the dealer has to do? but I think that I read somewhere that other have purchase new smartkey & have been able to get it fully functional. Anyone has any idea whats wrong?

 

I read the instructions they have on the forum http://priuschat.com/forums/knowled...lly-how-program-non-sks-key-fob-detailed.html on programing the key fob, the one that you have to put the key in & out, close & open the doors a couple time while patting your head & rubbing your stomach at the same time lol.

Is the unlock & lock functions part of the smart functions Because I can't get that function to work if I try to program it but I seen that others have got it to work on a new non smark key but can't get it to work on a used one. If my key that I try to program for the locks is not programing does it means that they sold me a used one because wouldnt it have program the lock & unlock if its not part of the smart key functions?

 

OK, today I took the key fob to get program at the dealer, they program the key & it works fine now. The program cost me a total of $115 + I had a coupon they mailed me & I got a $30 visa giftcard. The new key fob cost me $139 with shipping incl. Thanks to all who responded, I thought the instructions that were posted was going to work but I guess I was wrong, I was getting ready to ship the key back to the guy thinking that he sold me a used key fob instead of a new one because I couldn't get it to program.
