Toyota will NOT program SKS for two 2010 Prius vehicles

Actually a few year ago there was a class action regarding the such keys both from both Toyota and VW. Not only does Toyota have to allow buyers to have new keys made at a reasonable cost but I'm not even sure legally they can keep the programming for the Prius to allow new keys out of other places either. I think what has stopped that from happening is the tech needed to talk to the Prius cost to much for most keymakers to want to spend.

Now, I'm not sure from your posting if Toyota isn't able to get a new key smart key working or they are say that from some reason they don't want too. One is is likely not legal and the other would be a surprise as each Prius can match up with at least five keys.

Now I get it...you wanted to program your own keys. I don't think it can be done without a laptop and some software that can only be purchased from Toyota. The odd door opening technique that works for the non smart keys, simply won't work with a smart key. I'm surprised that Toyota simply didn't explain this to you. A few weeks ago, I went with with a friend who had lost their keys and only had a non smart key fob that they had bought on ebay. I watched out they programmed the Prius for the new keys. It takes about 10 minutes working on a laptop to clear the old keys and add new keys. It would take almost the same time to add smart keys too.

You wanted one smart key for two Prius's? That won't work, simply because of way the programing works when it comes to adding smart keys. Each smart key has an encryption code that the Prius has to read to match up with the key. Once the laptop adds the key, the code is locked away and the software can't use it any more. It's more a programming issue than a tech issue. I don't think Toyota will do what you want them to do as I understand it. Now if you could read the encryption code the key has, you could perhaps could do what you want as there is a manual add in the software as I remember it and one smart key could be added so it would work to each car. Though you wouldn't be able to park the cars near each other as whatever you did in one, it would do in both. The key wouldn't know what car it needed to connect too. Even the laptop doesn't know what the actual binary code as it's encrypted as that solution would likely be blocked.

Good luck in any case.

This is probably the same issue as trying to add a used keyfob. The SKS system only likes brand new keyfobs, and maybe slightly used ones. The Gen2 non-SKS remote may have a limit of 128 keypresses before it is disabled from being paired to a car. I say "may" because the security chip used in it has an optional setup that can do that, but nobody seems to know if that option is actually used. Some people have apparently paired a used non-SKS keyfob to their car, but I don't know of any cases where it worked for a SKS keyfob.

The transponder in the keyfob is another matter. Any Gen2 keyfob (2004-2009, SKS, non-SKS) can be paired with any number of cars. So on the Gen2, any old keyfob can be made to work with when inserted into the keyslot in the dash. 2010 is an unknown, but it's worth trying the first procedure in http://priuschat.com/forums/knowled...lly-how-program-non-sks-key-fob-detailed.html

If the Gen2 procedure works with the 2010, then you'll have a keyfob that can unlock the Power button when it's held next to it. I guess the Gen2 instruction to "insert keyfob" translates to "hold keyfob next to Power button". The range is quite short (an inch?).

If the transponder function is used to unlock the Power button, then you'll also need a mechanical key to lock/unlock the door. The 2010 mechanical key is generally referred to as a "laser cut" key, and requires specialized equipment to duplicate. Even a dealer may have to send out key duplication to a locksmith with the proper equipment. If I had a 2010 (drool...), I'd probably replace that laser cut key system with the older key mechanism used in Gen2. Probably about $50 for a replacement key cylinder, and $2 each for all the mechanical keys you can lose. That laser cut key is certainly more secure than the old style one, but it's also a high budget item.
