what would the price be to get a chrysler dodge van key with a chip made? and fob?

[His LadyBug]

I've lost my stupid keys... UGH!! My husband has the key to the van, but I'm wondering how much it would cost to get a key made with the chip in it that it takes to make the car start. Also wondering what kind of range the key fob would be... Thanks! Oh and also, can I just go to any dodge dealer to order it? and how long does it usually take to get it.
