Does anyone know if this warning message is set at mileage intervals, like the scheduled service intervals, or does the vechicle actually sense a lower signal from the key FOB? I assume the latter, but wanted to check.

I know on my wife's 2011 RX, if the key FOB battery is totally dead, you remove the valet key and hold the FOB close to the start button, and the vehicle will start. I assume the GS' also have the ability?

You're welcome. Glad you found the battery replacement easy...and inexpensive.

If you happen to be caught with a dead key fob battery, you can just hold the [intact] key fob next to the Start button and it will start...but I would not wait for that to happen. It's too easy and inexpensive to not replace the batteries every couple of years.
