OK, I did some looking about and found a couple relevant sites for info and product. Here's an article on how to homebuild a system. http://www.extremetech.com/article2/0,1697,1939007,00.asp Here's a site that sells all sorts of systems, from single entry to multi-user/multi-entry industrial stuff. http://www.nokey.com/ Here's another specialty retailer http://keylessentrylocks.com/ So, the stuff is out there. It's just a matter of how much money and time you're willing to invest. None of what I saw, though, really compares to the SKS on the Prius. Has anyone looked into the cost of SKS sensors and FOBs from Toyota? Seems you could build a system around them. Cost prohibitive?
