Yes - some threads address this FOB-ish reprogramming issue - but not many threads address Fob reprogramming specifically for the 2008 Prius. I successfully reprogrammed a used 2007 Fob I purchased on Ebay for a 2008 Model Prius - I have a Non-SKS (smart Key system) 2008 Base Trim Prius - These non-SKS Priuses use a Fob with a black emblem on the back to start the engine. However - I purchased an SKS FOB with a silver emblem on the back on EBAY for $79 which is meant only for a Prius with a SKS system (or so I thought) - I followed the instructions listed below - it took about 20 attempts and ta-dah - it worked!!!! My advice - you have to move fast and just keep at it - If I had done so to begin with, I probably could have reprogrammed the ebay FOB on the first or second try (doooo!!!!) so...I can now use the SKS FOB (silver emblem) to start my Prius, BUT I could not re-program the lock/ unlock feature on the FOB - no success there and that's what others seem to running up against. If any one has had success reprogramming the lock/ unlock feature as well on a Silver emblem FOB for a non-SKS Prius, please tell me what you did! Here is the original FOB reprogram link: http://priuschat.com/forums/knowled...lly-how-program-non-sks-key-fob-detailed.html and here is specifically what I did: The Fob (for operating the car) This isn't hard, as long as your new fob is not broken and you are able to follow simple directions. The whole process will take less than two minutes. 1. STRART WITH THE DOORS UNLOCKED/ and CLOSED. Then insert old fob into slot and remove it 4 times in a row, then insert it a fifth time and leave it in. 2. Open and close driver door 6 times. 3. Remove old fob from slot. Car is in fob programming mode at this point and I think the Red anti-theft auto icon will stay permanently illuminated in this step. 4. Insert new fob and leave in the slot for a full minute. Watch the blinking red anti-theft light on the dashboard. When it stops flashing and goes dark, your new fob is all set. For me, this took no longer than 10 seconds. 5. Remove the new fob and you're done. You should test both fobs to be sure they work properly. As for a key that will lock/ unlock the doors, I will just have to get a few spare metal keys cut at the dealership and hide them. I just cannot seem to reprogram the lock/ unlock feature on the fob at all - Please - if you have a new 2008 Prius and have attempted this in any format - share your knowledge.
