I work at a dealership, just went and pulled both key blanks. Aside from the fact that they are both PK3 style keys, I don't think the resistors in the head of the key would be compatible, but the blanks themselves are vastly different and wouldn't work either ignition.

The cylinders are different as well as the tumblers inside so you would have to change out the entire lock cylinder just to get the style key you want and even then the security system probably wouldn't work.

Sorry but you're stuck with that key.
