It will need to be ordered.
Programming the remote is easy.
The blade must be ordered to fit.
Also the key has an rfid in it that need to match the ignition. The dealer needs to order it by Vin #.
If the rfid does not match the cars ignition it will start run for two seconds and shut off.
And no, an rfid cant be reprogrammed.
Hope this helps...
I got one off ebay and learned the hard way.
Also it is just about impossible to disassemble the key fob without destroying it.
