The physical proximity required for keyless entry (via handles) seems to be quite small -- smaller than the width of the car. Thus, you need to be on the same side of the car as the key in order to unlock it by grabbing a handle.
The car doesn't need to be terribly "smart" for this feature... just have transponders on both sides of the car (probably inside the doors) with suitably small ranges.
I agree. If I have the key, my wife cannot open the door from the passenger side. Also, I'm a runner, and I don't like carrying my key with me when I run. If I put the key on the top of the wheel (doesn't matter which one), the proximity sensor still works (i.e., the door will open if you touch the handle). But, if I put the key under the front fascia in the center, neither door will open.
Taking a bit of an offramp here, has anybody tried the keypad that Ford sells on their website with our cars? When I look at the application list, it doesn't have our car listed; in fact, it infers that it won't work if the car has keyless start. My brother used to have a Ford Explorer with keyless start, and the truck also had the keypad (not as an add-on, was built-in to the design).
