Are Old (2005-2007) Dodge/Chrysler Minivan Keys Worth Anything?

I had two Dodge Grand Caravans wrecked. Between the two of them, I have 5 keys just sitting around at home, two of which I paid for. My question is - can you replace just the blade portion of the key (which is matched to the ignition switch). If you can't replace the blade portion, can you hack off the blade portion, use a cheap ignition only key and reprogram the electronic part of the full-function key?
