How much would it cost to replace a 2009 Toyota Siena car fob?

I lost the key and fob to my 2009 toyota siena. How much would it cost for a new set? Also, i have a replacement set for the car, but i need a second set. Would having a second set make the price less?|||About a hundred bucks.|||A new programmed fob will set you back as much as $100.00. That all depends on what the dealer charges. 'They ain't cheap'.
