Has anyone been able to get an aftermarket smart key installed? I will have 4 children 3 and under soon. Going to get the 2011 or 2012 Honda Odyssey Touring because of the number of LATCHes as all my children are still in car seats and none in boosters. The only downfall is no smart key... this would be really handy for a mom with TWIN infant car seats in both hands or a toddler's hand in both hands... oye vay! Anyway, it seems convenient for someone in my position and would love to get this installed. Has anyone been able to get an aftermarket smart key installed? How much was it? Where did you get it done? I found a kit online for $500, but when I call the Honda service department here to ask about it, they seem really confused (they are thinking remote start or just a different key with the buttons). I'm talking about the smart key that Nissan and Toyota have, where you don't have to dig the keys out of the diaper bag or purse to unlock the doors.
