he's saying u need all the i-keys to be programmed together, bc the car ereases all the codes for all i-keys.
Also, with only the key of the intelligent key (without the fob )my car won't turn, so i think the transponder is on the remote...correct me if I'm wrong.

hey guys, I'm new here (just got an 05 sedan), I'm from the max.org.
I thought that you could program the i-key by yourself, just like the non-intelligent key for nissans and infinitis....i hate paying the dealer.
The independent dealer programmed one of the keys I had and they did not have a machine for this.
