can used key fob be reprogrammed by the car?

I've never tried that tool, but many of the cheap Chinese tools don't work with Prius. You're better off getting mini-VCI/Techstream and programming the fob that way, even if you have to buy a seedcode from someone like PinOnline Software

 

Kaptainkid1, do you still have at least one working fob for the car? If not I think you will have to pay lots of money at the dealer as I think you can only program a new fob yourself by using a working fob to program it. Others with more info will chime in with better information on steps you will need to take.

I have a back up sks key fob which works. I bought a used SKS key fob but I didn't think It would need a machine to program a used SKS key fob. Should have read this thread before buying a used key fob.

I see mini VCI and tech stream tools on ebay for around $70. I'm not sure if these tools have the software for my Prius to reprogram my used SKS key fob. They say they have TIS which means?
Can I buy any ebay tools to reprogram used SKS key fobs?

Look at this on eBay

I think if your NEW key is a virgin key (meaning it has not ever been programmed) you can do the SKS full chicken dance and program it. At least that is the way I understand it.

I bought a new china knock off Virgin SKS Key from ebay. It cost $109 total shipped. Did the chicken dance and all the smart Key functions worked no problem.
The plastic case is a little cheap but you can swap out to an OEM key fob. Totally worth for $109 vs $300 OEM toyota dealership key.

Nice! That is good info and glad it worked out for you and saved $200!
I got a hold of a used smart fob (but it doesn't matter smart of not) and did the first part of the programming so the fob starts the car in the slot and just had a hardware store cut a key. No smart functions but a really cheap solution.

silver backed fobs from dealer should be UNDER 130 bucks, lots of dealers sell for that price, i am getting one today. If your dealer is sticking it to you on a fob, they are making you their girlfriend on every thing you do with them.

 

I'm not sure where you got that idea as the MSRP for the SKS fob is currently $253.94 and a lot of online dealers will discount to around $185.

If you are seeing pricing at around $130 that would be the discounted price for a non-SKS fob.

If sellers are selling for a lot less than that, they are either cheap aftermarket knockoffs or are counterfeits.
