I'd also be interested in knowing how..
Just for S&G's I tried a little experiment to see just how many smarts Toyota put into this system.
I got into the car with the FOB in my pocket. Started the engine (by turning on the heat). Got out of the car and walked away from it - The car gave it's little electronic beep 3 times to warn me that it was turned on and I was leaving it behind. I pulled the Fob from my pocket and laid it down on my back steps. Went back to my running car, got in and drove off. All the while I was driving the display was warning me that the Fob was not detected! But it gave me full control anyway.
I guess I was hoping that the salesman was right that the car would not let me drive away without the Fob.
It would make sense for the car to not allow itself to be driven off without the fob wouldn't it?
We KNOW Toyota has the technology and a lot of sound reasoning behind how and why they did things. I just wonder about this one. Maybe a dealer configurable option??
