well, these new transponder keys are a different ani-mule. on our Town and Country, you can program a new key to the system by going thru a set of steps with the on board car computer, turning the key on and off etc, and that will match a new key to your car. Toy prolly has a similar deal. The dealer has a machine they can do it with as well. I got my info from a key purveyor on EBay.
