Are you saying the starter will not crank the engine?

He can try inserting the fob in the slot in the glove compartment.

My 05 would not start a couple of times. One time it was a relay (relays are on the passenger side front wheel well under the hood). I think I got it started by swapping the AC relay in for the start relay. It has been years since I did this, so my memory may not be exactly correct.

The next time the BCM (body control module) was bad and had to be replaced.

Hope this helps.

Changing car battery does not erase fob programming. Is the new battery fully charged?
