What I'm most interested in is the max distance the FOB can be to start the car. For example, if one were to have a standard key copy made w/o FOB, it wouldn't start the car. But will it start if the FOB is in the glove compartment, or other nearby location?
Check this programming guide, there is some extra info which might help:
