Just want to share my find with everyone. Hopefully this info is worthy of a new thread... The programming procedure below enables SKS functionality for NEW SKS key fobs! This is contrary to everyone's post about SKS functionality being non-user programmable. It worked for me and I'm sure it will work for others as long as the Key fob is new. http://priuschat.com/forums/attachments/gen-ii-prius-care-maintenance-troubleshooting/23259d1273397060-important-experience-key-fob-programming-issues-d__applications_prius_key-programming_smartkey-pro.pdf Thanks to AbuS3ood for providing the document.
