2004/2005 option packages AG, AM, BI, BG, and BC come with the Smart Entry & Smart Start/Smart Key System. [edit - added in the AM package. I missed it on my list, it was hiding...]hlclark78 said:I think the 2004 should get the buttons as the 2005 is pretty smart with the sensors under the handles.... or does that 2004 have that too?
The rolling code is in the fob, not the car. You program the car to accept the rolling code. I do know though, that programming in the fob is tricky. Many dealers have had trouble.calinkus said:Conclusion: One Key for two cars? Yes, for starting and running.
No, for locking and unlocking doors.
If you purchase a used FOB, forget even the dealer to program the door locks. The key code is only programmed once.
The above info came by trial and error on my part.
